Hi,

I'm trying to find all images in an html file. Therefore, I'm looking for a way to save the content of a page with all html tags in a text file and then search for "<img" keyword to find the picture.

I have been searching google for that, but I couldn't find any function in PHP which can do that for me.

Any idea what function I have to use?

one way out of the many

<?php
$pattern = '/<img(.*?)>/';
preg_match($pattern, $htmlfile, $matches);
print_r($matches);
?>

I like ghostdog74's idea but if you want ALL the images I'd search for common file extensions used (.jpg, .jpeg, .gif, .png) because some tags will use <img src="dfdfgdfgdfg.jpg"> and other tags could be <body background="dfgdfgd.gif"> or <td background="dfgdfg.png">.

Just a thought

Peace

You're also going to miss a ton of images on modern websites which often use the CSS background-image property for its flexibility and because it's not obtrusive. It also allows for easy layering. I'd suggest searching linked CSS files for image extensions to round out this scan.

umm, the OP did say he was looking for <img ... so why not just do that?

Thank you very much. I'm not really interested in pictures which are specified in CSS.
