php regex : get src value

Question

How do I retrieve all src value using regex in php?

Answer 1

/src=(["'])(.*?)\1/

example:

';
$count = preg_match('/src=(["\'])(.*?)\1/', $input_string, $match);
if ($count === FALSE) 
    echo('not found\n');
else 
    echo($match[2] . "\n");

$input_string = "";
$count = preg_match('/src=(["\'])(.*?)\1/', $input_string, $match);
if ($count === FALSE) 
    echo('not found\n');
else 
    echo($match[2] . "\n");

gives:
