Is there a way in PHP to setup a pointer to another variable, change it which changes the initial variable?
So, for example:-
$arr[6]['cnt'] = 0;
$currentPointer = $arr[6]['cnt'];
$currentPointer++;

//Should echo out 1
echo $arr[6]['cnt'];
I know my code doesn't work, and I know its wrong, but I have no idea how pointers work in PHP, or if its even possible.
Any suggestions?

Pointer to variable as a variable

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
