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.


The following below is a simple example -

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


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

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

Alright guys! This is where we are rounding up for this tutorial post. In our next tutorial guide, we are going to be discussing about the PHP Function Parameters.
