This package can manage the PHP configuration values of php.ini.

It can read the values of a php.ini file, get option values, change option values and save the modified settings to the current or a new php.ini file.

The package attempts to validate the types of values passed to each setting using a configuration CSV file that has the type information for each value.

The original formatting and comments are preserved when writing back the modified contents. Quoted values will remain quoted, and unquoted values will remain unquoted. So if you use a diff utility you can easily note what was changed.

PHP uses a php.ini file to read values that configures many aspects of the way PHP code works.

If you change one configuration value but set it to an incorrect type, PHP may not work as you expect and you may take a long time to figure what you did wrong.

The class provides a solution that can not only read and change php.ini settings, but it also can verify if you are setting those values to the correct types that PHP is expecting.

It uses a knowledge base file that contains the types of values that PHP expects for most of the configuration settings, so it can validate all the values and tell you if you set any values incorrectly.

<?php


    /****************************************************************************************************





        This example file demonstrates the use of the PhpSettings class.





     ****************************************************************************************************/


    require_once ( 'PhpSettings.phpclass' ) ;





    if  ( php_sapi_name ( )  !=  'cli' )


        echo ( '<pre>' ) ;





    // Load settings defined in file "example.php.ini"


    $settings    =  new PhpSettings ( 'example.php.ini' ) ;





    // Change the "memory_limit" setting.


    // Note that we could have used :


    //    $settings -> Set ( 'memory_limit', '127M' ) ;


    $settings -> memory_limit    =  '127M' ;


    echo ( "Memory limit set to 127M instead of 1024M\n\n" ) ;





    // Enable extensions that are already listed in file 'example.php.ini', but are commented out


    echo ( "Enabling disabled extensions 'mbstring' and 'exif'\n\n" ) ;


    $settings -> EnableExtension ( 'mbstring' ) ;

    // Enable an extension that is not listed in file 'example.php.ini'


    echo ( "Enabling undefined extension 'unknown'\n\n" ) ;


    $settings -> EnableExtension ( 'unknown' ) ;





    // Display the list of currently defined extensions ; you should see the 'mbstring' and 'exif' extensions,


    // which were initially listed in the 'example.php.ini' file but commented out, along with the 'unknown'


    // extension, which has just been added


    echo ( "List of enabled extensions :\n" ) ;


    echo ( "--------------------------\n" ) ;


    echo ( "\t" . implode ( "\n\t", $settings -> GetEnabledExtensions ( ) ) . "\n\n" ) ;





    // Save the modified contents to file 'example.php.out' 


    $settings -> SaveTo ( 'example.php.out' ) ;


    echo ( "Modifications saved to file example.php.out\n\n" ) ;





    // Run a comparison between the original version ('example.php.ini') and the modified one ('example.php.out')


    exec ( 'diff -Z example.php.ini example.php.out', $output ) ;


    echo ( "Comparison results :\n" ) ;
