It is possible to do this with ajax and php, ajax request to php file which will get the desired from you url and after that u can use RegExp or other method to get the title from the page content.
PHP Script to fetch the web page content will look like:
<?php
function get_url_contents($url){
$crl = curl_init();
$timeout = 5;
curl_setopt ($crl, CURLOPT_URL,$url);
curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
$ret = curl_exec($crl);
curl_close($crl);
return $ret;
}
header('Content-Type: text/html; charset=utf-8'); // needed to display the right encoding
echo get_url_contents('http://example.com');
//echo file_get_contents('http://example.com');
?>
The only thing who you will need to do is how to get the title from that page.

You can make a serversite proxy. Open the url from a local server site file.
I once made one in PHP: proxy.php
<?php
function content_type($filename) {
$mime_types = array(
'txt' => 'text/plain',
'htm' => 'text/html',
'html' => 'text/html',
'php' => 'text/html',
'css' => 'text/css',
'js' => 'application/javascript',
'json' => 'application/json',
'xml' => 'application/xml',
'swf' => 'application/x-shockwave-flash',
'flv' => 'video/x-flv',
// images
'png' => 'image/png',
'jpe' => 'image/jpeg',
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
'gif' => 'image/gif',
'bmp' => 'image/bmp',
'ico' => 'image/vnd.microsoft.icon',
'tiff' => 'image/tiff',
'tif' => 'image/tiff',
'svg' => 'image/svg+xml',
'svgz' => 'image/svg+xml',
// archives
'zip' => 'application/zip',
'rar' => 'application/x-rar-compressed',
'exe' => 'application/x-msdownload',
'msi' => 'application/x-msdownload',
'cab' => 'application/vnd.ms-cab-compressed',
// audio/video
'mp3' => 'audio/mpeg',
'qt' => 'video/quicktime',
'mov' => 'video/quicktime',
// adobe
'pdf' => 'application/pdf',
'psd' => 'image/vnd.adobe.photoshop',
'ai' => 'application/postscript',
'eps' => 'application/postscript',
'ps' => 'application/postscript',
// ms office
'doc' => 'application/msword',
'rtf' => 'application/rtf',
'xls' => 'application/vnd.ms-excel',
'ppt' => 'application/vnd.ms-powerpoint',
// open office
'odt' => 'application/vnd.oasis.opendocument.text',
'ods' => 'application/vnd.oasis.opendocument.spreadsheet',
);
$ext = strtolower(array_pop(explode('.',$filename)));
if (array_key_exists($ext, $mime_types)) {
return $mime_types[$ext];
}
elseif (function_exists('finfo_open')) {
$finfo = finfo_open(FILEINFO_MIME);
$mimetype = finfo_file($finfo, $filename);
finfo_close($finfo);
return $mimetype;
}
else {
return 'application/octet-stream';
}
}
// Website url to open
$daurl = $_SERVER["QUERY_STRING"];
header("Content-type:" . content_type($daurl));
// Get that website's content
$handle = fopen($daurl, "r");
// If there is something, read and return
if ($handle) {
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
}
?>
And then using ajax call like this:
proxy.php?http://www.google.dk/index.html
But but but....
This depends on your server, does it understand PHP and does it allow you to open cross-domain files using PHP?
Else this script is determination the content-type from extension html
, php
, css
, json
, etc.
And then you can use jQuery ajax method to receive the content:
var url = "proxy.php?http://www.google.dk/index.html";
$.ajax({
url: url,
type: 'get',
dataType: 'html',
success: function(data){
var dom = $(data);
var title = dom.find("title").text();
}
});
Hope it helps!
