Answer 1

I would suggest using this more flexible non-greddy regex:

This will be ignored.
Lorem ipsum..
This will be ignored.
This will be ignored.
asdlaskjd>This will be ignored.
This will be ignored.
Something:
This will be ignored.
This will be ignored.

Something else...

 be ignored.
END;
$regex = "/\s]+))?)+?\s+href\s*=\s*(\"(http:\/\/[^\"]+\/(.*?)\.(jpg|jpeg|png|gif))\"|'(http:\/\/[^']+\/(.*?)\.(jpg|jpeg|png|gif))'|(http:\/\/[^'\">\s]+\/([^'\">\s]+)\.(jpg|jpeg|png|gif)))\s(\s*\w+(\s*=\s*(\".*?\"|'.*?'|[^'\">\s]+))?)+>[^<]*?<\/a>/i";
$replaced = preg_replace($regex, '', $test_data);

echo '
'.htmlentities($replaced);
?>
