Regular Expression replacement

Hello,

I want to replace all accurences of the substring
width:000px (where 000 is any 3 digit number)
with the string
width:800px.

For example the following string :
style="width:400px; height:326px;" id="VideoPlayback"
type="application/x-shockwave-flash"
should be changed to
style="width:800px; height:326px;" id="VideoPlayback"
type="application/x-shockwave-flash"

so I used the following command :
$pvid = str_replace("width:[1-9][0-9][0-9]px","width:800px",$pvid) ;

but it does not seem to work.

Any ideas on this?

Thnaks beforehand.

/width\s*?:\s*?\d{1,3}px/i

Re: Regular Expression replacement

Thanks for your reply Steve.

I tried what you suggested
$pvid = str_replace(" /width\s*?:\s*?\d{1,3}px/i","width:800px",$pvid) ;
but unfortunatelly did not work.

i just used:

/width\s*?:\s*?\d{1,3}px\s*?;?/i

as the pattern, this as the string to search:

width:400px; height:326px;" id="VideoPlayback"

and this as the replacement:

width:800px;

and i got this as the result:

width:800px; height:326px;" id="VideoPlayback"

seems to work for me. sorry it does not for you.

btw, look at the replacement string above. it starts with " /width"...note
the space. that may make a difference.
