PHP: Read out particular PHP settings
Question by Guest | 2016-02-24 at 10:48
I know, that it is possible to use the function phpinfo() in order to show a large list of all PHP settings available.
However, I do not need the entire list, but only some values of a few specific parameters to get some information about my configuration.
Is there any possibility to only display a specific value instead of the whole list? For example, only the values for "post_max_size", "upload_max_filesize" or another key?

Yes. PHP is providing a function for this and the function is called ini_get(). You can pass your desired parameter to this function and you will get the corresponding value from your PHP configuration:
echo ini_get('post_max_size'); $umf = ini_get('upload_max_filesize'); echo $umf;The result could be 16M, for example. If you would like to have the value in bytes, you have to multiply by 1024 in case of a K or by 10366976 in case of M.
