Details

INTRODUCTION

Wamp has a really fine user interface, but it's not always straightforward to understand how various Apache, MySql and PHP versions are or can be installed.

The WampManager class allows you to drive Wamp from within a script ; it provides the following features :

  • Since Wamp does not write anything in the Windows registry, the WampManager class is able to detect if a Wamp installation resides in the root of any of your partitions (you can also define a WAMPDIR environment variable that points to the installation directory).
  • It can retrieve all the Apache, MySql and PHP versions currently configured with your Wamp installation.
  • It gives the currently active Apache, MySql and PHP versions, and allows you to switch between existing versions.
  • It allows you to start/stop/restart any or all of the running services
  • It can restart Wamp if you changed settings in the configuration
  • You can configure additional MySql services, using different my.ini files

Instantiating a WampManager object is fairly simple :

include ( 'WampManager.phpclass' ) ;

$wamp 	=  new WampManager ( ) ;

If the class finds a valid WAMP installation directoy on your system, it will return a valid instance ; otherwise, an exception will be thrown.

You will have access to properties such as PhpPackages, MySqlPackages and ApachePackages which are array objects giving you access to the settings of each package.

The Php, MySql and Apache properties will return you the currently active version of each product.

You will also have access to the WAMP installation and logs directories through the InstallationDirectory and LogsDirectory properties. The WampExecutable property will give you the complete path of WAMPMANAGER.EXE.

The WampManager::$WampManagerConfiguration static property wraps the contents of the WampManager.conf .INI file located at the root of the installation directory and allows you to retrieve or change settings.

REFERENCE

WampManager class

The WampManager class is the top-level class to access the inner settings of your WAMP configuration, start and stop services, etc.

Methods

Constructor

 $wamp 	=  new WampManager ( ) ;

Creates a WampManager class instance and reads all the settings defined in your current installation. Note that creating a WampManager instance does not mean launch WampManager. At this stage, only an object is created, and it does not affect your running instance of Wamp.

The class searches the root of each of all your non-removable partitions to locate a directory that looks like "\Wamp\". Of course, if such a directory has been found, it effectively checks that it contains the traditional tree hierarchy of Wamp ; this means :

  • A WAMPSERVER.EXE executable
  • Various configuration files
  • At least one version of the MySql, Apache and PHP packages with their corresponding executables and configuration files
  • To be considered as configured for Wamp, each MySql/Apache/PHP directory must contain a WampServer.conf file.

You can override this behavior by defining the WAMPDIR environment variable to point to your Wamp installation directory.

ConfigurationChanged

$wamp -> ConfigurationChanged ( ) ;

Call this method whenever you have made any changes to the WampManager.conf file through the WampManager::$WampManagerConfiguration object. It will save any changes performed so far and restart Wamp.

Restart

$wamp -> Restart ( $verbose = false ) ;

Restarts all the running services (Apache and MySql) along with Wamp itself.

Debug messages will be displayed if the $verbose parameter is set to true.

Note that PHP itself is not to be considered as a service : it is a DLL used by Apache.

SaveConfiguration

$wamp -> SaveConfiguration ( ) ;

Saves the currently loaded Wamp configuration.

This method is a shortcut for :

WampManager::$WampManagerConfiguration -> Save ( ) ;

Start

$wamp -> Start ( $verbose = false ) ;

Starts all the Wamp services (Apache and MySql).

Debug messages will be displayed if the $verbose parameter is set to true.

Note that PHP itself is not to be considered as a service : it is a DLL used by Apache.

Stop

$wamp -> Stop ( $verbose = false ) ;

Stops all the Wamp services (Apache and MySql).

Debug messages will be displayed if the $verbose parameter is set to true.

Note that PHP itself is not to be considered as a service : it is a DLL used by Apache.


Properties

Apache

Returns the currently active Apache version (of type ApachePackage).

ApachePackages

An array of type ApachePackages containing ApachePackage objects that give information about your currently installed Apache versions.

InstallationDirectory

Returns the directory of your current Wamp installation.

LogDirectory

Returns the logs directory of your current Wamp installation (normally, unless modified, this should be a directory named logs directly under the installation directory).

MySql

Returns the currently active MySql version (of type MySqlPackage).

MySqlPackages

An array of type MySqlPackages containing MySqlPackage objects that give information about your currently installed MySql versions.

Php

Returns the currently active PHP version (of type PhpPackage).

PhpPackages

An array of type PhpPackages containing PhpPackage objects that give information about your currently installed PHP versions.

WampExecutable

Returns the full path of WAMPMANAGER.EXE.

WampManagerConfiguration

This static property gives you access to your current Wamp settings, through an object of type IniFile. You can retrieve them and modify them.

You can find more information about the IniFile class here :

https://www.phpclasses.org/package/9413-PHP-Load-and-edit-configuration-INI-format-files.html

Packages collections (WampPackages classes)

The WampManager package comes with 3 classes that represent a collection of installed Wamp packages :

  • ApachePackages, which contain entries of type ApachePackage
  • MySqlPackages, which contain entries of type MySqlPackage
  • PhpPackages, which contain entries of type PhpPackage

Each collection inherits from the WampPackages file. They currently do not add any new behavior to their base class, but only have different constructor parameters.

The ApachePackage and MySqlPackage classes inherit from the WampService class ; the PhpPackage class inherits from WampModule.

Both WampService and WampModule classes inherit from WampPackage.

The following sections describe the properties and methods of the WampPackages class, which apply to all of its derived classes. Since this class is mainly used internally, most of the properties and methods are given here for informational purposes only.

Note that this class implements the ArrayAccess, Countable and Iterator interface, so that you can loop through a package list as if it were an array.

Methods

Constructor

$Packages	=  new WampPackages ( $name, $class, $parent, $rootdir, $prefix, $active_version ) ;

Creates a list of Packages whose configuration information is to be loaded.

Since this is an abstract class, it is the responsibility of derived classes (PhpPackages, MySqlPackages and ApachePackages) to provide the required parameters appropriate to their function.

The parameters are the following :

  • $name (string) : Official list name ("PHP", "MySQL", "Apache").
  • $class (string) : Name of class deriving from WampPackage which is responsible for loading package data.
  • parent (WampManager object) : Parent WampManager object.
  • rootdir (string) : Base directory under Wamp root (eg, 'bin/php').
  • prefix (string) : Prefix string used to name directories under $rootdir. For example, it will be 'php' for PHP versions (they all start with the string 'php'), 'mysql' for mysql version, 'apache' for apache versions.
  • active\_version (string) : The derived class must retrieve the currently active version from wampmanager.conf. It will be 'phpCliVersion' in the [phpCli] section, 'apacheVersion' in the [apache] section, and 'mysqlVersion' in the [mysql] version.

Note that the documentation about this constructor is for informational purposes only, since it is used internally by the WampManager class.

GetActivePackage

$package 	=  $packages -> GetActivePackage ( ) ;

Returns the object corresponding to the currently active version of the related product (PhpPackage for PHP, MySqlPackage for Mysql and ApachePackage for Apache.

A typical usage could be :

$package 	=  $wamp -> MySqlPackages -> GetActivePackage ( ) ;

which is also equivalent to :

$package 	=  $wamp -> MySql ;

GetActiveVersion

$version 	=  $packages -> GetActiveVersion ( ) ;

Returns the active version as a string for the related product. A typical usage could be :

$version 	=  $wamp -> PhpPackages -> GetActiveVersion ( ) ;

GetVersions

$list 		=  $packages -> GetVersions ( ) ;

Returns a list of versions for the related product ; the following example retrieves the currently installed PHP versions :

$versions 	=  $wamp -> PhpPackages -> GetVersions ( ) ;

SetVersion

$status 	=  $packages -> SetVersion ( $version, $reload = true ) ;

Sets the currently active version. If the $reload parameter is false, the change will be effective after restarting WAMP.

VersionExists

$status 	=  $packages -> VersionExists ( $version ) ;

Checks if the specified version exists. This is equivalent to :

$status 	=  isset ( $packages [ $version ] ) ;

Properties

Name

Returns the underlying name of the package collection : either "PHP", "MySql" or "Apache".

Package classes

Package classes are objects contained in a package list ; they have the following hierarchy :

					                WampPackage
			                             |
			                        WampModule
			                             |
			             +---------------+--------------+
			             |                              |
			       WampService                     PhpPackage
			             |
		 +---------------+--------------+
		 |                              |
	ApachePackage                 MySqlPackage

WampPackage is the abstract base class for all WAMP modules (Apache, MySql and Php). The WampModule class further defines the behavior of an installed module. Then comes a fork in the hierarchy :

  • PhpPackage classes directly inherit from WampModule
  • The ApachePackage and MySqlPackage classes inherit from the WampService class, which is a descendant of WampModule that provides additional methods specific to Windows services.

The following sections describe the methods and properties exposed by each class.

Package class : WampPackage

The WampPackage is the abstract base class for all WAMP modules.

Methods

Constructor

$package 	=  new WampPackage ( $name, $parent, $path, $version, $exedir, $exefile, $confdir, $conffile ) ;

Instantiates a WampPackage object ; the parameters are the following :

  • $name (string) : Name of the package (PHP, MySql or Apache)
  • $parent (WampManager object) : Parent WampManager object.
  • path (string) : Path, in the WAMP installation directory, of the specified package (eg, C:\Wamp\bin\php\php5.6.12)
  • version (string) : Version string
  • exedir (string) : Directory containing the package executable, which can be a subdirectory of $path.
  • $exefile (string) : Full executable path.
  • confdir (string) : Directory containing the configuration file.
  • conffile (string) : Full configuration file path.

Note : this constructor is used internally. It is not meant to be called from within a script.

GetConfigurationFiles

$files 	=  $package -> GetConfigurationFiles ( ) ;

This abstract function is meant to return the paths of all the configuration files handled by the underlying package.

GetLogFiles

$files 	=  $package -> GetLogFiles ( ) ;

This abstract function is meant to return the paths of all the log files handled by the underlying package.

Properties

ConfigurationDirectory

Returns the path of the configuration directory for the underlying package.

ConfigurationFile

Returns the path of the main configuration file for the underlying package.

ExecutableFile

Returns the path of the executable file for the underlying package.

Name

Returns the name of the underlying package (PHP, MySql or Apache).

Path

Returns the installation path of the underlying package.

Version

Returns the package version string.

Package class : WampModule

This class extends the WampPackage class by adding the following methods :

IsRunning

$status 	=  $package -> IsRunning ( ) ;

Checks if the specified module is currently running.

Restart

$package -> Restart ( ) ;

Restarts the specified module or service.

Start

$package -> Start ( ) ;

Starts the specified module or service.

Stop

$package -> Stop ( ) ;

Stops the specified module or service.

Package class : WampService

This class extends the WampPackage class by adding the methods described below ; note that the Install/Uninstall methods are not yet implemented to create/remove new httpd services and will throw an exception.

Install

$package -> Install ( $service_name, $configuration_file ) ;

Installs a new instance (Windows service) of the underlying package.

Uninstall

$package -> Uninstall ( $service_name ) ;

Uninstalls a existing WAMP Windows service.

Package class : ApachePackage

This class extends the WampService class by adding the following methods :

GetModules

$list 	=  $package -> GetModules ( ) ;

Returns the list of currenly declared Apache modules.

Package class : MySqlPackage

This class can install additional Windows MySql services or remove them. Note that in the supplied configuration file, the main section name defining the host port, the database directory, etc. must match the service name you supply to the Install()* method.

For example, WAMP 64-bits has a section named [wampmysqld64] in its my.ini file. If you want to install a service named "foobar", then the configuration file you specified will need to have a [foobar] section for defining MySql parameters.

A gentle reminder :

  • You cannot start a second MySql service on the same port that the currently running one
  • You cannot start a second MySql service using the same database directory as the existing one

Package class : PhpPackage

This class extends the WampService class by adding the following methods :

GetModules

$list 	=  $package -> GetModules ( ) ;

Returns the list of currenly declared PHP modules.
