PHP Local 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 Local Variables.

A variable declared in a function is regarded local; that is, it can only be made referenced to in that function. Any assignment outside of that function will be considered an entirely different from the one contained in that function.

Example

The following below is a simple example -

<?php
   $x = 10;
   
   function assignx () { 
      $x = 0;
      print "\$x inside function is $x. <br />";
   }
   
   assignx();
   print "\$x outside of function is $x. <br />";
?>

Output

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

$x inside function is 0. 
$x outside of function is 10.
