[RESOLVED] Change to preg_replace instead of ereg_replace

halojoy

I get the message that ereg_replace() is deprecated.
So, I want to change the following line
to use [man]preg_replace[/man]

$text = "<p>".ereg_replace("(\n){2,}", "</p><p>", $text)."</p>";

Thanks!

I found it out myself.
Simply add / in begining and end.

$text = "<p>".preg_replace("/(\n){2,}/", "</p><p>", $text)."</p>";

Those slashes are called delimiters. Delimiters don't have to be slashes however.. they can be any non alpha-numeric, non whitespace non backslash character. You can read up about delimiters here:

http://www.php.net/manual/en/regexp.reference.delimiters.php

Also, from what I gather, you shouldn't need to use a capturing group for \n (as $1 isn't really being used). You could simply use /\n{2,}/

Yes, right.
No need to capture.
I know we can use for example ## as delimiters.
Actually I often prefer ## before //, because they have better visibility and differ more from other slashes, backslashes in the code.

Thanks, nrg_alpha
Good to have guys like you and Weedpacket, who can help us with more difficult regex.

[ i don't understand where am i wrong...
(ereg_replace deprecated: ereg_replace(".(.).","\1",$string);
with: preg_replace("#.()(.)().#e","$2",$string);
this function doesn't work...) ]
