Proxy Php Url
How to proxy another page in PHP – Stack Overflow
I’m looking for the fastest and easiest way to proxy a page in PHP. I don’t want the user to be redirected, I just want my script to return the same content, response code and headers as another remote URL.

echo file_get_contents(‘proxypage’);
Would that work?
EDIT:
First answer was a bit short, and I don’t believe it will handle headers as you would like.
However you can also do this:
function get_proxy_site_page( $url)
{
$options = [
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => true, // return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => “”, // handle all encodings
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects];
$ch = curl_init($url);
curl_setopt_array($ch, $options);
$remoteSite = curl_exec($ch);
$header = curl_getinfo($ch);
curl_close($ch);
$header[‘content’] = $remoteSite;
return $header;}
This will return you an array containing lots of information on the remote page. $header[‘content’] will have both the content of the website and the headers, $header[header_size] will contain the length of that header so you can use substr to split those up.
Then it’s just a matter of using echoand header to proxy the page.

You can use the PHP cURL functions to achieve this functionality:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, ”);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// grab URL and pass it to the browser
$urlContent = curl_exec($ch);
From this point, you would grab the response header information using. (There are several values you can grab, all listed in the documentation).
// Check if any error occured
if(! curl_errno($ch))
$info = curl_getinfo($ch);
header(‘Content-Type: ‘. $info[‘content_type’]);
echo $urlContent;}
Make sure to close out the cURL handle.
// close cURL resource, and free up system resources

You can get the html of the next page with curl, and then echo the response.

Instantly share code, notes, and snippets.
then simply do a local
({
url: ‘/’,
onComplete: function(data) {
(data);}})();
to make it safer, you can just hardwire the url into the proxy and possibly append escaped search terms or whatever so these will become your only argument.

your php script is not retruning any data at the moment. you still need an echo/print;)
It was not intended to be fully functional but fair enough:)
Simple PHP Proxy – Jon LaBelle
With Simple PHP Proxy, your JavaScript can access content in remote webpages, without cross-domain security limitations, even if it’s not available in JSONP format. Of course, you’ll need to install this PHP script on your server, but that’s a small price to have to pay for this much awesomeness.
