[PHP] Removing Empty Lines from Text??
Is there an elegant way to remove excess blank lines from my form data? For example; if someone enters the following text and then press' the Submit button: This is a some text This is more text, and yet even more What I want to do is remove the excess white space and make it look like this? This is a some text This is more text, and yet even more My users may press enter too many times and I want to ensure clean text and formatting. Thanks.

Well, in short, you want to replace \n\n\n or \n\n\n\n with \n\n.
This can be done cleaverly with a regexp (not my expertise at all, but you
want to replace 3 or more occurences of \n in a row with \n\n.
Otherwise, a simple str_replace() will do it an okay job.
something like:
?
$str = something\n\nwith\n\ntoo\n\n\nmany\n\n\n\nline\nbreaks;
$str = str_replace('\n\n\n','\n\n',$str) // change three enters to two
$str = str_replace('\n\n\n\n','\n\n',$str) // change four enters to two
?
Untested of course.
Like I said, a regexp would be better here.

To add my tuppence's worth, I would search for and remove any white spaces between \n's as well. Something like replace \n\s*\n with \n. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* It's a .88 magnum -- it goes through schools. -- Danny Vermin */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
