Browser Detection

[php.ajax.coder]

I am using the following function to fetch a web pages source code but there is a problem when a page has a browser detection script is there any way to make the server think that it is a browser and not a script

function getSource($url){
//@ this removes the warning messages
$source = @file_get_contents($url); 
if (empty($source)){
	return "No Source";	
}else{
	return $source;	
}
}

 

Thanks

You could try something like:

 

<?php
header("User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.7) Gecko/2009030516 Ubuntu/9.04 (jaunty) Firefox/3.0.7");
?>

You need to use curl instead of file_get_contents, and add the headers like

 

curl_set_opt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.7) Gecko/2009030516 Ubuntu/9.04 (jaunty) Firefox/3.0.7');

Actually, when you think about it, that makes a lot more sense - My suggestion won't work.

Could you explain how I use this in my function

Have you checked the manual? cURL and PHP

You don't need to use cURL, you can set the user agent with ini_set():

 

<?php
ini_set('user_agent', 'Mozilla/5.0 (Windows; U; Windows NT 6.0; da; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7');
function getSource($url){
   //@ this removes the warning messages
   $source = @file_get_contents($url);
   if (empty($source)){
      return "No Source";   
   }else{
      return $source;   
   }
}
?>

I think CURL will help you. I used below function to fetch source code of a webpage :

 

function read_web_page($url) {
   $ch = curl_init($url);
   $fp = fopen("d:/test.txt","w");
   curl_setopt($ch, CURLOPT_FILE, $fp);
   curl_setopt($ch, CURLOPT_HEADER, 0);
   curl_exec($ch);
   curl_close($ch);
   fclose($fp);
}

 

pass url of any webpage and it wil save source code to test.txt in D drive. Change it as per your requirement,
