java regular expression PHP extracts the image address in the string [regular expression]

Copy code The code is as follows:

$str='

';
$pattern="/<[img|IMG].*?src=['|"](.*?(?:[.gif|.jpg])) ['|"].*?[/]?>/";
preg_match_all($pattern,$str,$match);
print_r($match);
?>

The result shows:
Array
(
[0] => Array
(
[0] =>
)
[ 1] => Array
(
[0] => upfiles/2009/07/1246430143_1.jpg
)
)

The above introduces the java regular expression PHP to extract the image address in the string [regular expression], including the content of java regular expression. I hope it will be helpful to friends who are interested in PHP tutorials.
