[snip!]

Change this:
$pattern='p\s+style=padding-left:\s+(\d+)px;(.*?)/p';

To this:
$pattern='/p\s+style=padding-left:\s+(\d+)px;(.*?)\/p/Uis';

This adds the delimiters (/) to the beginning and end of the
string, and escapes the slash in the /p so it doesn't kick-out
early, leaving trailing characters.  After the ending delimiter, it
tells preg_replace() to be Ungreedy, CASE-iNSENSITIVE, and to feel
free to cross over newline boundaries (with the 's' modifier).

From there, you can modify your regexp as needed.

One of the absolute best resources for regexp's on the 'Net today,
in my opinion, is here:

http://www.regular-expressions.info/

It's even good for those of us who forget things years later ;-P

[PHP] Preg_Replace $pattern syntax error

[Graham Anderson]

Hi

How can I convert the regular expression:p\s+style=padding-left: 
\s+(\d+)px;(.*?)/p

into a pattern that PHP will accept?

I am getting the error:
Warning: preg_replace() [function.preg-replace]: Unknown modifier '('  
in /Library/WebServer/Documents/tamagotchi/runtime/content/js/tiny_mce/ 
examples/tinymce_regex.php on line 24


I am very new to regular expressions and any help is appreciated.  
Something to do with escaping certain strings?

$html =EOB
TinyMCE is a span style=font-style: italic;platform/span
p style=text-align: center;We recommend a href=http://www.getfirefox.com 
 target=_blankFirefox/a /p

p style=padding-left: 30px;May the Regular Expression Find Me!/p
EOB;

$pattern='p\s+style=padding-left:\s+(\d+)px;(.*?)/p';
$replace= 'textformat indent=\\1\\2/textformat';
echo preg_replace($pattern,$replace, $html );

[PHP] Preg_Replace $pattern syntax error [solved]

[Graham Anderson]

I needed to add the ~ character as a delimiter. So, the below now works
$pattern='~p\s+style=padding-left:\s+(\d+)px;(.*?)/p~';
