Unset all variables

[dotkpay]

Hello,

Am writing a script with lots of variables and its called by require() into the main file. But I probably have an interference in variable values because I get incorrect results.

I have to unset all variables first before I enter the new script but there are lots of them. Is there a way I can unset all variables with a simple line of code or function?

Thanks in advance

This is not a good programming practice, but if you want the job to be done...

<?php
$variables = array_keys(get_defined_vars());
foreach($variables as $variable) {
    unset(${"$variable"}); 
    // You can reset them to empty string - ${"$variable"} = "";
}
?>

use unset

http://php.net/manual/en/function.unset.php

unset($variable1, $variable2, $variable3);

 

OR

try this one

foreach (array_keys($GLOBALS) as $variables) unset($$variables);unset($variables);

Can you create a new file called "unset_variables.php"

 

In there unset each variable you think you are ever using.

 

Then (now and in the future) if you ever want to unset everything you can just do..

 

require_once unset_variables.php

 

That work?
