We're going to learn about the function, str_replace - more info can be found at PHP's manual at this link: http://www.php.net/str_replace

str_replace(what you're looking for, what you wanna replace it with, where you're looking);

So, as an example:

$msg = "Dan is alright.";
$bettermsg = str_replace("alright", "god", $msg);
echo $bettermsg;

This would print: Dan is god.



You can also use it with arrays. Say we had a string full of pointless numbers, this snippet would clean it out for us.

$msg = "1He3l64lo 4w5o865rl1d2.";
$numbers = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "0");
$cleanmsg = str_replace($numbers, "", $msg);
echo $cleanmsg;

This would print: Hello world.


Hope this is of help to people in their scripts and applications. :)
