PHP Static Variables

​​

Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial guide, we will be discussing about the PHP Static Variables.

The final type of variable scope is the static variable. In contrast to the variables declared as function parameters, which are destroyed on the function's exit, a static variable will not loose its value when the function exits and will still hold on to the value should the function be called again.

You can declare a variable to be static by placing the keyword STATIC in front of the variable name.

Example

The following below is a simple example -

<?php
   function keep_track() {
      STATIC $count = 0;
      $count++;
      print $count;
      print "<br />";
   }
   
   keep_track();
   keep_track();
   keep_track();
?>

Output

When the above code is executed, it will produce the following result -

1
2
3
