如何使用preg_match获取“id或更多的html标题”？

Question

I am using

preg_match("/\<title\>(.*)\<\/title\>/i",$str,$title);

to get

<title>Exapmle</title>

How can I get this using preg_match?

<title id="ANY_ID">Exapmle</title>

I am using this to get page title. Maybe, a title can have more than 'id'
While answering, please keep that in mind.

Okey. Here is a complete code to get page title. Hope that it helps others.

 function get_title($url){ $str = file_get_contents($url); $str = trim(preg_replace('/\\s+/', ' ', $str)); // supports line breaks inside <title> $match = preg_match("/\\<title(.*)\\>(.*)\\<\\/title\\>/i",$str,$title); // tries to catch if the title has an id or more // if first prag_match gets an error // (that means the title tag has no id or more) // it tries to get title without id or more if ($match === false) { preg_match("/\\<title\\>(.*)\\<\\/title\\>/i",$str,$title); } return $title[1]; }

You can add (.*) which match any characters. Note that last element of $title is your title

preg_match("/\<title(.*)\>(.*)\<\/title\>/i",$str,$title);
