Let's assume this is what I'm working with...<br /><br />$string = 'xxxxxxxxyyyy';<br />$regex = 'xxxxxxxx';<br /><br />And my goal is to have the following results...<br /><br />$value1 = 'xxxxxxxx';<br />$value2 = 'yyyy'; (Remainder after $regex)<br /><br />What commands am I using to get to that point?<br />I have used regex to remove and/or alter text, but<br />I have never used them to split apart a string.<br /><br />I can hack around to get a result, but I prefer to<br />do it as 'properly' as possible and minimizing lines<br />and execution cycles.<!--content-->
I believe preg_split() may be what you want. Check out: <a href="http://www.php.net/manual/en/function.preg-split.php" target="_blank">http://www.php.net/manual/en/function.preg-split.php</a><br /><br />On second thought, it doesn't look like there's anything separating the two parts of your string so it may not be exactly what you're looking for.<!--content-->
OK, looks like this should give you what you want.... I think <img src="http://www.totalchoicehosting.com/forums/style_emoticons/default/smile.gif" style="vertical-align:middle" emoid="
