如何使用php获取标签之间的数据[关闭]

Question

if I have input like this <n>336197298</n> how do I get the number between the tag by using php programming. I try to use regular expression but I can't find the method for this task. Could you please help me .

Answer 1

i think regular expression is best try this method,

function get_content( $tag , $content )
{
    preg_match("/<".$tag."[^>]*>(.*?)<\/$tag>/si", $content, $matches);
    return $matches[1];
}
