Regex & PHP - isolate src attribute from img tag

Question

With PHP, how can I isolate the contents of the src attribute from $foo? The end result I\'m looking for would give me just \"http://example.com/img/image.jpg\"

You can go around this problem using this function:

function getTextBetween($start, $end, $text)
{
 $start_from = strpos($text, $start);
 $start_pos = $start_from + strlen($start);
 $end_pos = strpos($text, $end, $start_pos + 1);
 $subtext = substr($text, $start_pos, $end_pos);
 return $subtext;
}

$foo = '';

$img_src = getTextBetween('src="', '"', $foo);
