如何检查 php_ini 变量是否设置？

Question

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 next line for testing.

Answer 1

Use the function ini_get .

Answer 2

You can use ini_get('memory_limit');

Answer 3

Adding an live example

<?php

echo ini_get("memory_limit");

?>

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