php查找问题

怎么查找一个文章里包含有abc.com域名下的JS。
如一个字段时有XXXXXXXXXXX <script></script>XXXXXXXsdfa

回复讨论(解决方案)

用正则吧，无敌的正则帮你匹配，你只要做个判断匹配到就输出，正则现在本人不会写，可以在这里求诸大神们帮忙

$s=<<<txt如一个字段时有XXXXXXXXXXX<script src='http://www.abc.com/js/aaa.js' language='javascript'></script>XXXXXXX<a href="www.abc.com">sdfa</a><script src='http://www.def.com/js/bbb.js' language='javascript'>txt;preg_match_all("/<script[^>]*src='.+abc\.com[^>]+>/sU",$s,$m);print_r($m[0]);

Array
(
    [0] => <script> <br /> ) </script>

$s=<<<txt如一个字段时有XXXXXXXXXXX<script src='http://www.abc.com/js/aaa.js' language='javascript'></script>XXXXXXX<a href="www.abc.com">sdfa</a><script src='http://www.def.com/js/bbb.js' language='javascript'>txt;preg_match_all("/<script[^>]*src='.+abc\.com[^>]+>/sU",$s,$m);print_r($m[0]);

Array
(
    [0] => <script> <br /> ) <br /> 输出时少了</script>

preg_match_all("/<script>]*src='.+abc\.com[^>]+><\/script>/sU",$s,$m); </script>

但是你主贴中并没有套红  
要懂得尊重别人！！！
