Re: [PHP] String manipulation with ereg_replace

 I am working on a site that has over 1000 pages and all the images need to
 be made lower case in the HTML.
 Here is what I have so far. Please someone tell me what I am doing wrong.


 $contents="img src=ThisOneReallyNeedsToBeAllLowercase.gif
 alt=ThisOneReallyNeedsToBeAllLowercase.gif";

 $contents =
EREG_REPLACE("([-_a-zA-Z0-9]+).gif",strtolower("\\0"),$contents);


 Output of $contents needs to equal
 img src=thisonereallyneedstobealllowercase.gif
 alt=thisonereallyneedstobealllowercase.gif





You need to use preg_replace which supports evaluating PHP code for the
replacement. To use preg functions you need to have compiled PHP with PCRE
(Perl Compatible Regular Expression) support.

http://www.php.net/manual/function.preg-replace.php3

This should do the trick (untested!):

?
$contents = "img src=ThisOneReallyNeedsToBeAllLowercase.gif
alt=ThisOneReallyNeedsToBeAllLowercase.gif";

$contents = preg_replace("/([-_a-zA-Z0-9]+)\.gif/e", "strtolower('\\1')
. '.gif'", $contents);
?


Cheers

simpler that
"/([-_a-zA-Z0-9]+)\.gif/e"
is
"/([-\w]+)\.gif/e"
