How to check php_ini variables are set?

I am overriding php.ini variables in my code. (ini_set("memory_limit", -1);)

How can i make sure it is set. Am using windows machine.

Is there any way i can read variable by variable with some GLOBAL array or something ?

Once i set variable, i want to read it in the 开发者_StackOverflownext line for testing.

Use the function ini_get.

You can use ini_get('memory_limit');

Is this what you are after? PHP manual

Adding an live example

<?php

echo ini_get("memory_limit");

?>

Output:
128M (based on the value set in your php.ini).

Please see the link below for working example:
