[RESOLVED] preg_replace question

[ungovernable]

hi,

i'm a bit confused,
i have a variable called $thread['threadprefix'];
how could i use preg_replace to remove all the text that is following a " - " in the value returned by $thread['threadprefix'];

ex: for "abc - def" keep only "abc"

$new_str = str_replace(strstr($str, '-'), '', $str);
// or
$new_str = substr($str, 0, strpos($str, '-'));

If you want to use preg_replace():

$new_str = preg_replace('/ - .*/', '', $thread['threadprefix']);

str_replace() is normally faster than preg_replace, though there may not be much difference in this case since the str_replace() solution requires calls to other string functions, though practically speaking either method in this fairly simple case will probably be within a millisecond or two of each other.

thanks a lot! i'll look for str_replace() the next time, but it's working perfectly right now!
