Your middle segment, "[^\{php}]*" is telling the system to took for any
character that's not a "{", "p", "h", or "}", and perhaps even a "\".  
So, any time it encounters one of those characters, the regex evaluates
to false.  It's best to replace it with ".*" and add the "ms" flags.

   $out = preg_split("/({php}.*{\/php})/ims", $text, -1, 
PREG_SPLIT_DELIM_CAPTURE);

I don't know if this does what you really want it to since what it does 
is kind of strange and you didn't specify what your goal is.

Good luck,

[PHP] PCRE - catching a caracter set in a negative class

[Maxim Maletsky]

Hi all, 

I was scratching my head to accomplish the following perl regular 
expression. It doesn't want to catch me [^\{php}]. From what I understood 
reading the docs this is because in a negative class the caracters are being 
taken litteraly one by one and not as a set. I tied to enclose them by () by 
that didn't work eigher. What is the work around for this? 


here's a sample code: 


$text = ' 

some text ... 

{php}
echo "some funcy code to include he{re";
{/php} 

more text 


'; 

$out = preg_split("/(\{php}[^\{php}]*\{\/php})/i", $text, -1, 
PREG_SPLIT_DELIM_CAPTURE); 

 

Thanks,
