<a href="" with Class

Question

I was in tourble on my simple project...

I'm trying to grab all the links from tag a href tag, but my problem is that the links also have other attributes, that is class.

This the source structure:

<a class="coolCard project-card " href="http://www.aabbcc.com/post//tank-farm-good-be" id="2568"> 

What i tried so far is:

preg_match_all('/<a\s*class=\"coolCard \s[^\>]*\"\s*href=([\'"])(.*?)\\1/is', $wordString, $links); 

For result, i want to get the link http://www.aabbcc.com/post//tank-farm-good-be

おかげで....

Answer 1

あなたが正規表現で余分なスペースを持っているからのリンクを取得preg_match_all：

preg_match_all('/<a\s*class=\"coolCard \s[^\>]*\"\s*href=([\'"])(.*?)\\1/is', $wordString, $links); 
//        here __^ 

ジュストそれを削除します。

preg_match_all('/<a\s*class=\"coolCard\s[^\>]*\"\s*href=([\'"])(.*?)\\1/is', $wordString, $links); 

を。

$wordString = '<a class="coolCard project-card " href="http://www.aabbcc.com/post//tank-farm-good-be" id="2568">'; 
preg_match_all('/<a\s*class=\"coolCard\s[^\>]*\"\s*href=([\'"])(.*?)\\1/is', $wordString, $links); 
print_r($links); 

出力：

Array 
(
    [0] => Array 
     (
      [0] => <a class="coolCard project-card " href="http://www.aabbcc.com/post//tank-farm-good-be" 
     ) 

    [1] => Array 
     (
      [0] => " 
     ) 

    [2] => Array 
     (
      [0] => http://www.aabbcc.com/post//tank-farm-good-be 
     ) 

)
