'; if (preg_match_all('/src="(.+?)"/', $str, $matches)) { print_r($matches); } else { echo '没有匹配'; }

Output:

( [0] => Array ( [0] => src="/public/upload/ueditor/image/20170626/1234567890.png" [1] => src="/public/upload/ueditor/image/20170626/0987654321.png" ) [1] => Array ( [0] => /public/upload/ueditor/image/20170626/1234567890.png [1] => /public/upload/ueditor/image/20170626/0987654321.png ) )

If you are interested, please watch my introductory lecture on regular expressions: Learn to use regular expressions in one hour

Regular expressions are more convenient

Use regular matching, and then use()to extract the piece as a subset

$str = ""; preg_match_all("/image\/(\d+\/\w+\.(png|jpeg|gif|jpg))/", $str, $matches);

 
'; preg_match_all('/]*src=\"(.+?)\"/', $tt, $matches); var_dump($matches); // 需要的字符串在$matches[1]中，具体信息可以打印了看
