PHP + Regular Expressions

Question

I'm having a hard time trying to remove duplicated images from an specific text/article.

Let's say that I have an image tag where the src="http://domain.com/image.jpg" and I want to remove(/hide) all the images that have the following pattern:

http://domain.com/image-999x999.jpg

Currently, my regex expression is (and it isn't working):

'/'.preg_quote('src="http://domain.com/image-').'([0-9]{3}\x[0-9]{3})\.(gif|png|jpg)/i'

(the regex, as an example, should ignore this: http://domain.com/image-20-999x999.jpg)

Any suggestions are more then welcome!

Cheers,

Probably the \x, as it should most likely be x instead. Either that or the src=" part... — Kenaniah

In this case the preg_quote() isn't working, because you left out the second parameter. It needs to know your used delimiter, else it can't escape it:

 preg_quote('src="http://domain.com/image-', '/')

Preferrably you could use another delimiter for the regex itself however. Like # that isn't present in your base href. And you don't actually need the quoting if it's just that fixed string.

try

preg_match_all('/src="http:\/\/domain\.com\/image\-\d{3}xd{3}\.(gif|png|jpg)/'
                inputHTML, $imgs);

I haven't tried this yet, I hope it works :)
