Use the env command. The env command returns a list of all global variables that have been defined. If a global variable exists in a script that hasn't been run yet, it will not show up in the output from env .
A global variables list (GVL) is used to declare global variables. If a GVL is placed in the Global node of the Software catalog > Variables > Global Variables or the Applications tree, the variables will be available for the entire project.
There are about nine superglobal variables in PHP which are sometimes referred to as automatic globals .
$GLOBALS is a PHP super global variable which is used to access global variables from anywhere in the PHP script (also from within functions or methods). PHP stores all global variables in an array called $GLOBALS[index].
Yes, PHP $GLOBALS array will show you.
<?php echo "<pre>"; print_r($GLOBALS); echo "</pre>"; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
