Question

I’m trying to figure out the best way to unset a php session variable, after all pages have loaded and the page will be rendered to the browser. I have a page that includes & requires several pages to be rendered. I want to know if there is a built in php function that will tell php to do something right before the page is completed. Or what would the best way/practice to do this?

EDIT##
Here’s what I added…

function unsetHIST_ID(){unset($_SESSION['Hist_CID']);}
register_shutdown_function('unsetHIST_ID');

Answer 1

Am not sure why you want this but if you want a function to be executed after script execution finishes or exit() is called then you should look at register_shutdown_function

Example

function shutdown() {
    echo "Am dead anyway";
}

register_shutdown_function('shutdown');

echo "<pre>";
echo "Hello am Alive",PHP_EOL;

Output

Hello am Alive
Am dead anyway <---------------This would always run last
