preg_match_all has some limits?

[Mauro D.]

Hi guys,
i'm trying to replace a picture inside an RTF file.

I have found that this is the format the picture is described inside RTF:

{\*\shppict{\pict\picscalex80\picscaley80\piccropl 0\piccropr0\piccropt0\piccropb0\picw800\pich600\pi cwgoal12000\pichgoal9000\jpeglib
....some binary data...}}

RTF file is about 3,9MB and this expression "\{\\*\\shppict{\pict(.*?)}}/"

doesn't return anything that i can change.

My wish is to change attribute of the string that I have paste on the
top and obviously change binary data!

Thanks

Mauro

I'd switch to single quotes around the PHP string to avoid added confusion
with slashes - it's tricky enough already.

Consider for example (which appears in your expression):

"\\s"

The actual value of that string is:

\s

Because the first slash escapes the second in PHP, and the s is a literal
character.

So \s reaches the PCRE engine, which interprets this as "whitespace
character".

Do you want something more like (and I've not quite convinced this is right
either):

'/\{\\*\\\\shppict\\{\\\pict(.*?)}}/'
