This package * is also included mysql, pgsql, oci8 database interaction to * generate xls files. * Limitations: * - Max character size of a text(label) cell is 255 * ( due to MS Excel 5.0 Binary File Format definition ) * * Credits : This class is based on Christian Novak's small * Excel library functions. ******************************************************************/ if( !defined( "PHP_SIMPLE_XLS_GEN" ) ) { define( "PHP_SIMPLE_XLS_GEN", 1 ); class PhpSimpleXlsGen { var $xls_data = ""; // where generated xls be stored var $default_dir = ""; var $filename = "psxlsgen"; // save filename var $fname = ""; // filename with full path var $crow = 0; // current row number var $ccol = 0; // current column number var $totalcol = 0; // total number of columns var $get_type = 0; // 0=stream, 1=file var $errno = 0; // 0=no error var $error = ""; // error string var $dirsep = "/"; // directory separator var $xls_stName = "Erol Özcan"; // Default constructor function PhpSimpleXlsGen() { $os = getenv( "OS" ); $temp = getenv( "TEMP"); // check OS and set proper values for some vars. if ( stristr( $os, "Windows" ) ) { $this->default_dir = $temp; $this->dirsep = "\\"; } else { // assume that is Unix/Linux $this->default_dir = "/tmp"; $this->dirsep = "/"; } // begin of the excel file header $this->xls_data = pack( "ssssss", 0x809, 0x08, 0x00,0x10, 0x0, 0x0 ); // WRITEACCESS: Write Access User Name /* $name = str_pad( $this->xls_stName, 111, " " ); $this->xls_data .= pack( "ss", 0x5c,0x70 ); $this->xls_data .= pack( "C", 10 ); $this->xls_data .= $name; */ } // end of the excel file function End() { $this->xls_data .= pack( "ss", 0x0A, 0x00 ); return; } // write a Number (double) into row, col function WriteNumber_pos( $row, $col, $value ) { $this->xls_data .= pack( "sssss", 0x0203, 14, $row, $col, 0x00 ); $this->xls_data .= pack( "d", $value ); return; } // write a label (text) into Row, Col function WriteText_pos( $row, $col, $value ) { $len = strlen( $value ); $this->xls_data .= pack( "s*", 0x0204, 8 + $len, $row, $col, 0x00, $len ); $this->xls_data .= $value; return; } // insert a number, increment row,col automatically function InsertNumber( $value ) { if ( $this->ccol == $this->totalcol ) { $this->ccol = 0; $this->crow++; } $this->WriteNumber_pos( $this->crow, $this->ccol, &$value ); $this->ccol++; return; } // insert a number, increment row,col automatically function InsertText( $value ) { if ( $this->ccol == $this->totalcol ) { $this->ccol = 0; $this->crow++; } $this->WriteText_pos( $this->crow, $this->ccol, &$value ); $this->ccol++; return; } // Change position of row,col function ChangePos( $newrow, $newcol ) { $this->crow = $newrow; $this->ccol = $newcol; return; } // new line function NewLine() { $this->ccol = 0; $this->crow++; return; } // send generated xls as stream file function SendFile( $filename ) { $this->filename = $filename; $this->SendFile(); } // send generated xls as stream file function SendFile() { $this->End(); header ( "Expires: Mon, 1 Apr 1974 05:00:00 GMT" ); header ( "Last-Modified: " . gmdate("D,d M YH:i:s") .
