preg_replace with dash
Posted on 2011-03-04
Hi,
Just a quick question. I'm wondering if this code:
will replace all instances of any character that is a letter or number with the dash. It's supposed to create user friendly post slugs from title string to use within URLs.
Thanks,
Victor

Hai,
Just a slight modification there in your function
function create_slug($string){
$slug=preg_replace('/[^A-Z
return $slug;
}

The pattern you posted '/[^A-Za-z0-9-]+/' will replace all characters that are NOT 0-9, A-Z, a-z or a dash

[^ ... ]
Means any character not in this character set. Remove the chevron to make it any character in this set.

P.S.
The chevron only makes it a "not" when it is listed as the first character in the character set. Listed anywhere else, it is a literal character.

Examples:
[^abc] - Any character NOT a, b, or c
[abc] - a, b, or c
[abc^] - a, b, c, or chevron
[^abc^] - Any character NOT a, b, c, or chevron
[^^] - Any character NOT a chevron
"....Means any character not in this character set. Remove the chevron to make it any character in this set....."
Why didn't they use ! to mean NOT like many programming languages..... oh well
@vkimura2007 - I can understand your confusion look at this
/^[^a-z]+[a-z]*$/
That means "any string starting (^) with characters that are NOT a-z ([^a-z]) ..... " etc. It's unfortunate that regex syntax looks like the leftovers from the Scrabble box....
