How To Assigning A New Character In A String?

Answer»

The string element expression, $string{index}, can also be USED at the LEFT side of an assignment statement. This allows you to assign a NEW character to any position in a string. Here is a PHP script example:
<?php
$string = 'It\'s Friday?';
echo "$string\n";
$string{11} = '!';
echo "$string\n";
?>
This script will print:
It's Friday?
It's Friday!
