How to read php.ini values at runtime?

Question

I am writing a PHP library and to increase its portability and robustness I would like to be able to read the php.ini file to access the installation settings.

Is there a simple way to do this or do I need to do this the hard way and write code to parse this myself?

Thanks

Answer 1

I doubt that you need all of the php.ini file. For specific values, why not use ini_get()? For example, to get the maximum post size, you can simply use:

$maxPostSize = ini_get('post_max_size');

Answer 2

PHP has a nice support for INI files. Along with the php_ini_loaded_file() you can get the details of current ini file.

<?php 

    // get path to the ini file
    $inipath = php_ini_loaded_file();

    // Parse with sections
    $ini_array = parse_ini_file($inipath , true);
    print_r($ini_array);

?>
