PHP的正则表达式的帮助，过滤电话号码

Question

正则表达式大师请我想过滤像2338034444232，07065716184,0816272721。用逗号分隔电话号码，我希望我的最终产品像2338034444232,2338034444232,2338034444232。

感谢

Answer 1

$userinput=" 
    I believe Mr. Putin's number is 123456789only differing slight 
    from mine 1234567890124. I tried calling him 42 times but he won't answer. 
    "; 

$regex="/[0-9]{13}/"; 

preg_match_all($regex,$userinput,$out); 


foreach($out[0] as $o){ 

    echo $o; 
    echo ", "; 
} 

现在，如果用户要呼叫普京 1234567890124时候，你就会有一个问题。

这是你寻找的东西吗？
