RE: [PHP] Re: split on whitespace, preserving whitespace...

Several of these solutions are good ideas, but they don't preserve the whitespace as he desired. Preg_split with the capturing of the (\s+) delimiter does the trick.

Uuhmm, I'm sorry. I haven't read it throught to the end. The solution ist a bit different: use preg_replace to replace multiple spaces with single spaces: $sometext2split = preg_replace("|", " ",$sometext2split); #make shure that the separator isn't in the text anywhere around $sometext2split = preg_replace("/\s+/", "| |",$sometext2split); and then explode the string (i don't know wether explode or preg_split is faster, I tend to explode for simple split operations): $myarray = explode("|",$sometext2split); this should work. But probably it was a better solution to insert the spaces with a loop between the words than to run the risk, that the separator is somewhere in the text... best regards Stefan Rusterholz, scripting@interaktion.ch ----- Original Message ----- From: "Stefan Rusterholz" <scripting@interaktion.ch> To: <garth@utmail.to>; <php-general@lists.php.net> Sent: Friday, July 20, 2001 3:34 PM Subject: Re: [PHP] Re: split on whitespace, preserving whitespace... > If you'r using PHP >4 use preg_split.
