PHP Local Variables

PHP Local Variables


Hello folks! welcome back to a new edition 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 that function is going to be viewed to be an entirely different variable from the one that is 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.
