preg_replace: removing spaces at begining and end of a word

ungovernable

Hi,

Could anyone please tell me what syntax i need to use in preg_replace to take out the space at the begining and the end of a string?

thanks a lot!

Why use preg_replace? Why not [man]trim/man instead?

...your code will be assimilated, and it's technological distinctiveness stolen and reused as we see fit... lol

I personally would use trim as that would be the most... :rolleyes: efficient use of my time...

however not everyone values efficiency over all else... not everyone can be part of the collective... 😉

Let's use everything except trim(), or: my submission for this week's obfuscated code contest (if there was one):

$string = preg_replace_callback('/^(\s+.*|.*\s)$/', create_function('$m', 'return(ltrim(rtrim($m[0])));'), $string);

Kids! Don't do this at home without parental supervision!
