PHP: Regex (Preg_match_all) To get all links

I have the following:

preg_match_all("'HREF=\"([^>]*?)\"(.*?)'is",
             $messageBody,
               $linkHrefs, PREG_PATTERN_ORDER);

This works great if the link is correct (and has "" I believe). What the issue is if someone does this

<a href = "http://test.com"> <-- notice the spaces between href =

Another one could be

<a href='http://test.com'> <-- using ' instead of "

Is there any way to modify my regex so that it handles this alot more and gets MOST, if not all links, regardless of 100% perfection?

Thank you!

I would suggest using a delimiter other than single quote, but it is of course not mandatory  = )
preg_match_all("'HREF\s*=\s*\"([^>]*?)\"(.*?)'is", 
             $messageBody, 
               $linkHrefs, PREG_PATTERN_ORDER);

Correction:
preg_match_all("'HREF\s*=\s*[\"\']([^>]*?)[\"\'](.*?)'is", 
             $messageBody, 
               $linkHrefs, PREG_PATTERN_ORDER);
