Reading HTML Title in PHP

[otchster]

I am challenged with the task of writing a PHP script that will prompt the user for a website (ex: yahoo.com). When submitted, the PHP script will somehow open the web page as a file, somehow search the source, find the <title> tag, and return the title of the web page..

 

If someone knows an easier approach to this, I would appreciate it. Opening an entire website as a variable seems like a bit of overkill..

 

 

Heres where I'm at so far, I'm kind of looking for a push in the right direction. I've been googling for awhile now trying to find out how to tackle this, but searching for things like "php, website, title, web page, HTML" hasn't proved too successful..

 

thanks in advance

 

<?php


// Assigns $site from the form text box named "site"
//
$site = $_POST['site'];


$file = fopen($site, "r");

// This needs to open the text-source of the inputted webpage.  
// From here I will search for the <title> tag in the HTML...
//
echo "$file";

echo "<br><hr>";

?>

Take a look at file_get_contents and preg_match.

 

You'll probably even find an example somewhere in the regex board.

A simple approach using only string manipulations functions should be:

 

<?php
$data = file_get_contents('http://www.yahoo.com');
$title1 = strpos($data, '<title>') + strlen('<title>');
$title2 = strpos($data, '</title>');
echo substr($data, $title1, $title2 - $title1);
?>

 

Using regex should be better though.

Regex would do this, seriously o_o

 

$data = file_get_contents("SOME URL");
$pattern = "/<title>([^<]*)<\/title>/";
preg_match($pattern, $data, $matches);
//$matches is an array; $matches[1] will get the the data in the first () or the title
$title = $matches[1];
