PHP The static Keyword
Thumbs Up 
Normally, when a function is completed/executed, all of its variables are deleted. However, sometimes we want a local variable NOT to be deleted. We need it for a further job.

To do this, use the static keyword when you first declare the variable:

function myTest() {

    static $x = 0;

    echo $x;







Then, each time the function is called, that variable will still have the information it contained from the last time the function was called.
[b]Note:[/b] The variable is still local to the function.
