Normally, when a function is completed/executed, all of its variables are deleted.

0
To do this, use the static keyword when you first declare the variable:
Example
<!DOCTYPE html>
<html>
<body>
<?php
function myTest() {
static $x = 0;
echo $x;
$x++;
}
myTest();
echo "<br>";
myTest();
echo "<br>";
myTest();
?>
</body>
</html>

OUTPUT
0
1
2

Then, each time the function is called, that variable will still have the information it contained from the last time the function was called.
