PHP and Browser User Agent

For use in curl or what?

For curl it is:

curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9');

Select allOpen in new window

I've added this to me php page

<?php

curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; MSIE 9.0; WIndows NT 9.0; en-US))');

?>

Select allOpen in new window

It's still telling me I'm using Firefox when the code above should set it to IE 9

Any ideas on why it;s not working please?

Anyone please?

Hi,

Use firefox then download addon called: User Agent
you can change user agent of your browser to anything you
want to pretend, example:

iphone,
IE8,
IE9,
Safari,
googlebot
msnbot

hope that help.

I've got that addon but this I need to do it via the web page as it's for a simulator.

Hi error77,

It would depending on whether you are trying to access the web page itself pretending to be a different web browser (user agent) or whether your PHP code retrieves content from a remote resource and you want this process to appear as a different browser (user agent).

I believe if you want to open a page in your web browser (Firefox) but have the web site believe you are using a different user agent then boon86's answer above would be correct.  The alternative would be in your code where you check what user agent the request came from simply override this with the desired user agent for testing.  Another alternative would be to use the browser with the desired user agent.

If, however you would like your PHP code to request content from a remote resource impersonating a specific user agent then the answer from RIk-Legger is correct presuming your are using CURL to retrieve the data.  The alternative if you are using fopen() etc would be to use:

ini_set('user_agent', 'Mozilla/5.0 (Windows; U; MSIE 9.0; WIndows NT 9.0; en-US)');

Please note I haven't tested the above suggestions however they have what I've come up with from Google results.

I hope these suggestions help, my apologies if they do not.

Cheers

Sorry but none of the examples work...

At the top of my page I have:

ini_set('user_agent', 'Mozilla/5.0 (Windows; U; MSIE 9.0; WIndows NT 9.0; en-US)');

Select allOpen in new window

Then unde that I have:

 echo $_SERVER['HTTP_USER_AGENT'];

Select allOpen in new window

and It's returning:

Mozilla/5.0 (Windows NT 6.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2

and not Internet Explorer ... why is it not working please?

<?php
    $url  = 'http://www.example.com/a-large-file.zip';
    $path = '/path/to/a-large-file.zip';
 
    $fp = fopen($path, 'w');
   
    $ch = curl_init($url);
    $ch = curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
    curl_setopt($ch, CURLOPT_FILE, $fp);
 
    $data = curl_exec($ch);
 
    curl_close($ch);
    fclose($fp);
?>

correction:

<?php
    $url  = 'http://www.example.com/a-large-file.zip';
    $path = '/path/to/a-large-file.zip';
 
    $fp = fopen($path, 'w');
    
    $ch = curl_init($url);
     curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
    curl_setopt($ch, CURLOPT_FILE, $fp);
 
    $data = curl_exec($ch);
 
    curl_close($ch);
    fclose($fp);
?>
