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


回复讨论(解决方案)

$str = '<input type="text" name="lname" />';  $str .= '<select><option value ="volvo">Volvo</option><option value ="saab">Saab</option><option value="opel">Opel</option><option value="audi">Audi</option></select>';preg_match_all("#((\<input.*\>)|(\<select.*\>.*\<\/select\>))#U",$str,$out);var_dump($out);


这样可否?

正则里有或‘|’这个操作符

PHP code?123456$str = '';  $str .= '
