Found a nice little tutorial to help understand how exactly preg_match() works.
Very useful when doing your validation for the forms thumbs up

PHPro Tut about preg_match

There is a much easier way of validation in PHP, without having to use regular expressions.

Look at filter_var()

Thanks bigron11! I was using the "FILTER_VALIDATE_EMAIL" already to check the emails which I find very handy.

Is it possible to use the filter_var() to just check for specific characters inside a variable? I had a look at the php.net and w3schools but can't see an example of that.
How would you use it to check, for example, if a variable contains only letters a-z and ' (single apostrophe) and spaces?

You can use filter_var() to do that. It has a FILTER_VALIDATE_REGEX option.

Look here -


There is also an interesting discussion here -

The filter_var() works great. A function that I make use of a lot to clean user input is this one:

Language: PHP
function txtValidate($Validated){ filter_var($Validated,FILTER_SANITIZE_SPECIAL_CHARS); filter_var($Validated,FILTER_SANITIZE_MAGIC_QUOTES); filter_var($Validated,FILTER_VALIDATE_EMAIL); filter_var($Validated,FILTER_SANITIZE_EMAIL); $Validated = mysql_real_escape_string($Validated); $Validated = ucwords($Validated); return $Validated; }

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning...
