php正则表达
怎么写一个正则,同时匹配两种标签
$pattern="#(\)#U";
$pattern="#(\.*\)#U";
像上面两,分别匹配了input和select。如何把它们合并成一个,只要满足其中一种都行。因为需要按照标签的顺序输出,所以不能分成两次来匹配


------解决方案--------------------
<br />
<br />
$str = '<input type="text" name="lname" />';  <br />
$str .= '<select><option value ="volvo">Volvo</option><option value ="saab">Saab</option><option value="opel">Opel</option><option value="audi">Audi</option></select>';<br />
<br />
preg_match_all("#((\<input.*\>)<br><font color='#FF8000'>------解决方案--------------------</font><br>(\<select.*\>.*\<\/select\>))#U",$str,$out);<br />
<br />
var_dump($out);<br />
<br />
Copy after login


这样可否?
