How to get a html title ?

Anon

I had written a code for get html title
but its work at sometime only...
Please told me what's problem

	$OpenFile = fopen($bkmarkurl, "r"); 
	if ($OpenFile != ""){
		$RetrieveFile = fread($OpenFile, 200000);  //- Reduce This To Save Memory
		$GrabData = eregi("<title>(.*)</title>", strtolower($RetrieveFile), $TagContent);
	}
	fclose($OpenFile);

What does it do when it goes wrong? Could you give some examples?

I'd note that since you're using eregi, you don't need to use strlower.

I'd also recommend the preg_match function instead - partly because I don't know how the ereg "." handles newlines, but I do know how to work with the preg syntax:

preg_match('|<title>(.*)</title>|is', $RetrieveFile, $TagContent);

Of course, any whitespace within the title tags will cause trouble if we don't account for it:

preg_match('|<\s?title\s?>(.)</\s?title\s*?>|is', $RetrieveFile, $TagContent);

I can't think offhand of any attributes or stuff that might also appear in a <title> tag.

If this isn't a help, then more detail will help towards a more appropriate response.

when it doesn't work, the broswer will nothing appear (just white background).

but it's not work anytime, so ask someone what going on at that php code.

I had test that code, its ready work.
Thnaks you a lot..

I want to ask something, what is the meaning of "is" at "|<title>(.)</title>|is'" and "\s?"
at '|<\s?title\s?>(.)</\s?title\s*?>|is'
Please told me and Thanks !!!

The "is" pattern modifiers have the following effects:

i: case-insensitive matching - you'll notice PHP has no "pregi" functions.

s: adjusts the meaning of "." in a regular expression, so that it counts newlines as characters as well. The default is that it doesn't, so "<title>\nTitle\n</title>" would fail to match if the "s" modifer wasn't added.
