Editor to share with you what the memory call mechanism of the PHP function is, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Code:

Function getVal ($num1,$num2) {$res = $num1 + $num2; return $res;} $res = getVal (10Magol 20); echo $res

Description:

1 the caller of the function passes the actual data to the function parameter, which can only be used within the function.

two。 When the function runs the code, it creates a new memory space to run the code of the function.

3. After running the code, if there is a return value that returns the result to the caller of the function, the new space for running the function is destroyed.
