Introduction
PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following example..
<?php $originalstring = 'tech- The Complete Debugging Solution'; $stringtoinsert ='study.org'; $insertpos = 4; $newstring = substr_replace($originalstring, $stringtoinsert.' ', $insertpos, 0); echo $newstring."\n"; ?>
