I have a PHP script on a server that generates the XML data on the fly, say with Content-Disposition:attachment or with simple echo, doesn't matter. I'll name this file www.something.com/myOwnScript.php
On another server, in another PHP script I want to be able to get this file (to avoid "saving file to disk") as a string (using the path www.something.com/myOwnScript.php) and then manipulate XML data that the script generates.
Is this possible without using web services?
security implications?
Thanks
Simple answer, yes:
$output = file_get_contents('http://www.something.com/myOwnScript.php');
echo '<pre>';
print_r($output);
echo '</pre>';
If you want more control over how you request the data (spoof headers, send post fields etc.) you should look into cURL.

If you're on a shared host, you might find that you cannot use file_get_contents. This mainly because it is part of the same permission sets that allow you to include remote files. Anyway...
If you're stuck in that circumstance, you might be able to use CURL:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "example.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
?>
It is more code, but it's still simple. You have the added benefit of being able to post data, set headers, cookies... anything you could do with a highly configurable browser. This makes it useful when people attempt to block bots.

I want to be able to go to mydoma.in/tunnel.php?file=http://otherdoma.in/music.mp3, and then get the data of http://otherdoma.in/music.mp3 streamed to the client.
I tried doing this via Header();, but it redirects instead of "tunelling" the data.
How can i do this?
Use cURL for streaming:
<?php
$url = $_GET["file"];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 256);
curl_exec($ch);
curl_close($ch);
?>
If they are small, you might be able to use file_get_contents(). Otherwise, you should probably use cURL. You would want to cURL the URL from the get variable "file". Then save it to a local temporary location with PHP. Then, use header() to direct yourself to the local file. Deleting the temporary file is the only issue, as there isn't really a way to determine when you have finished downloading it or not. So you might be able to sleep or delay the file removal, but you might find it's a better option to use a cron job to clean up all of the temporary files later.
Have your PHP script pull the remote content:
$data = file_get_contents($remote_url);
And then just spit it out:
echo $data;
Or simply:
echo file_get_contents($remote_url);
You might have to add some headers to indicate the content type.
Alternatively, you could configure a proxy with something like nginx -- this will allow you to rewrite particular URLs to a remote site and then serve them as local, no coding required.
I am searching 3 days for an answer and I cannot find one because I always find some obstacles.
I need to load a web page (the reason for this is to accept a cookie) and then at the same time read the source code of the new page without hitting it again. The reason for this is that the page is dynamic so the content will change.
I have tried to do this using iFrame(document.body.innerHTML) but the fact that these pages run on different servers I hit cross-site scripting issues.
I have also tried writing a php script using get_contents but this doesn't allow the cookie to be stored in my local.
This is driving me crazy.... Any suggestion will be helful! Need to use PHP or Javascript for this and any other suggestion will be useful as well.
When you are on the page document.body.innerHTML will give you the page source.
Edit: I didn't realize you were loading it like that. See this SO question.
It can be done using cURL in PHP.
A rough implementation:
$ch = curl_init('http://www.google.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$data = curl_exec($ch);
preg_match('/^Set-Cookie: (.*?);/m', $data, $cookies);
var_dump($cookies);
var_dump($data);
$data will contain the entire response, so we need to parse out the cookie headers ourselves.
If available on your system, HttpRequest would make this easier.
I would like to be able to send variables to another website without actually going to the website using php.
I am building an ecommerce website where the shipping warehouse is being outsourced. After the person checks out with their products, I would like to send some variables over to the shipper's website using $_GET['vars']. This is a completely different URL. The problem is, I don't want the person actually going to the shipper's webpage. I just want to ping that info over there.
Is is possible to send Variables via URL to another site without leaving yours?
Yes, you can. the simplest way:
$contents = file_get_contents("http://example.com/some/page.php?var=abcd");
For more advanced features see Curl.
You should be storing all the relevant order info within your database then using cron to trigger a script that will process the unprocessed, this way systematic checks can be made on orders before any request to your outsource site. Dont rely on your users browser to hit a curtain point in the order process to trigger the API call or trust them not to triple click or inject values before submitting.
And I advise to use curl todo your actual request as its faster. Something as simple as:
<?php
function curl_do_api($url){
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
?>
actually there is a more simpler way of solving this...using ajax
include the jquery header first
refer here
http://api.jquery.com/jQuery.ajax/
Both are right and you should make your choice based on security you're looking for.
cURL will be more secure and you should use it if you do not want to pass some argument in query string. At the same time when you pass data using file_get_cotents("URL?data=value"); you will have limit of about 2k for data being passed.
On the other side cURL will be secure if you use it with https it's much more secure. With cURL you will also be able to post files and emulate form post.
I need to make a POST in JSON format to an HTTPS web page in a remote server and receive an answer in JSON format.
The data to be send it to the remote server is take it from the URL (bar)<---Done in PHP
My problem is to send this data and receive an answer.
I tried making it in PHP, and HTML using cURL(php) and submit(html).
The results: In PHP I can't send anything.
In HTML I can submit the data, get an answer but I can't catch in my code.
I see the answer using Wireshark, and as I see the POST is make it after a negotiation protocol, and as I said I receive an answer(encoded due to HTTPS, I think).
Now I need receive that answer in my code to generate an URL link so I'm considering to use Java Script.
I never do something similar before.
Any suggestion will be appreciated, thanks.
I'm using the following code with not result but a 20 seconds of delay until a blank page.
<?php
$url = 'https://www.google.com/loc/json';
$body = '{"version":"1.1.0","cell_towers":[{"cell_id":"48","location_area_code":1158,"mobile_country_code":752,"mobile_network_code.":7,"age":0,"signal_strength":-71,"timing_advance":2255}]}';
$c = curl_init();
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS, $body);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($c, CURLOPT_HTTPHEADERS,'Content-Type: application/json');
$page = curl_exec($c);
echo($page);
//print_r($page);
curl_close($c);
?>
New info
I Just get new very important info
"The Gears Terms of Service prohibits direct use of the Google location server (http://www.google.com/loc/json) via HTTP requests. This service may only be accessed through the Geolocation API."
So, I was going trough the wrong way, and from now I will start to learn about Gears in order to apply the Gears API.
Cheers!
There's no real reason PHP couldn't do the PHP for you, if you set things up properly.
For instance, it may require a cookie that it had set on the client browser at some point, which your PHP/curl request doesn't have.
To do proper debugging, use HTTPFox or Firebug in Firefox, which monitor the requests from within the browser itself, and can show the actual data, not the encrypted garbage that wireshark would capture.
Of course, you could use the client browser as a sort of proxy for your server. Browser posts to the HTTPS server, gets a response, then sends that response to your server. But if that data is "important" and shouldn't be exposed, then the client-side solution is a bad one.
I wish to include JSPs include files which contain java code in a PHP template. The two includes in question are a header file, and a footer file. Anyone any experience of doing this? We are considering just doing a HTTP request to grab the resulting HTML from the JSP files independantly, but aren't sure if there will be slight performance issues with doing so.
Is there any better solution using some of the tools within Apache to perform this?
echo file_get_contents('http://full/link/to/jsp/page');
If you JSP page echos a header, body structure, you'll need to strip it out. You can do that from the JSP side or PHP.
That's disabled on some systems so you might need to use cURL (it also allows you to post back which you might need to do if you're playing with forms).
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_URL, 'http://full/link/to/jsp/page');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
echo curl_exec($ch);
You can't include a JSP page into a PHP page.
You can do what you are thinking of though: doing a HTTP request to get HTML content from JSP and embed that into the PHP result. Not pretty, but will work.
There is the Java / PHP Integration extension, but it doesn't allow to compile Java code. I don't think there is a way to compile Java from PHP, if not executing command line commands.
Depending on your requirements, if you don't want to impact page loading, you could also perform an AJAX request to grab the content once the HTML page is loaded, and inject it in the page : this would move the problem to the client.
Does this JSP page change frequently, or depend on PHP page's parameters (some kind of advertisement) ?
You could also cache the output of your JSP (even by parameters) for a pair of hours or a whole day, to avoid calling the page on every request.
