Simple Function in PHP

  • A function declaration starts with the special word 'function'.
  • A function name starts with a letter or  underscore, followed by any number of letters, numbers, or underscores.
  • A function names are case-insensitive.
  • A function is block of code that can be executed whenever we need it.

Syntax

function functionname()
  {
  code to be executed;
  }

Example

The following example show the simple function that writes any name when it is called:

<html>

<body>

<h2 style="color: steelblue;">Simple Function Loop example</h2>

    <?php

    function writeName()

    {

    echo "C-Sharpcorner";

    }

    echo "Welcome To...";

    writeName();

    ?>

</body>

</html>
