Hi all...


What is Variable Scope in PHP?


Thanks & Regards

Hi all...

In PHP you can't access a variable which is defined outside its scope. How is scope determined? In a PHP script, variables defined outside functions can't be accessed inside the functions.

<?php

$integer_var = 3;

function print_var(){
// this will NOT print 3 since $integer_var is not in the scope of this function
echo $integer_var;
}

print_var();

?>

Thanks...
