preg_replace problem (again!)

hmmm

[ahmedtheking]

Ok, how can i replace these chars " . + -" and any whitespace?

[Garfield]

You have to 'escape' all characters that are valid regex characters. To do so, just add a backslash in front of the character. For example: \+ or \. Whitespace can be done by /w

Hope it helps

Here's the regex if you need it:

[example]
$text = "some text + any-chars.";
$replacement = preg_replace("/[\+\.-\s]/", "", $text);
echo $replacement; // Returns "sometextanychars"
[/example]

So wot does "/[\+\.-\s]/" mean? Is there like a comprehensive guide?
