Question

I have the following code

$body = preg_replace('/<img(.*?)src="(.+)"/Ui','<img src="renderImage.php?image=\\2&width=<?=$img_width?>&url=<?=$mobiURL?>"',$body);

$body contains a whole html page that contains img tags, the above code works perfectly, but I need to exclude images with the string maps.google in it so that it does not get replaced.

Is there any way to do this

Answer 1

Method#1 :
Instead of altering your regular expression and making it more complex.
You can use preg_replace_callback instead.

In your callback function, you can ignore maps.google.com images.

Method#2 :

1. Invalidate IMG tages with maps.google.com src first.
   eg. convert a <IMG SRC='http://maps.google.com.... tag to

   <TEMPORARY_TAG src='http://maps.google.com...
   using regular expression.

2. Run your original regular expression to replace all IMG tags with your required snippet, that would not replace the ones with maps.google.com src as we had altered that IMG tag to TEMPORARY_TAG in step#1

3. Do reverse of step#1 , replace TEMPORARY_TAG in your HTML with IMG using simple string replace or regex.
