How to know the Proxy is working in curl/php - php

How to know that the proxy is working or not in curlphp
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_TIMEOUT, 0);
curl_setopt($ch, CURLOPT_PROXYPORT,8080);
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXY,'218.213.90.92');
$head = curl_exec($ch);
curl_close($ch);


You can set your $url to "https://soulogic.com/ip/"
If return ::ffff:218.213.90.92, it means proxy is working.
Or on your server side, make a PHP file wroten:
<?php
echo $_SERVER["REMOTE_ADDR"];

Stripe API - PHP Curl request behind a proxy

I'm trying to make a request behind a proxy to stripe api using php and curl. The following works if I'm not behind a proxy:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.stripe.com/v1/balance");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$a_pass");
$out = curl_exec($ch); # returns my balance
curl_close($ch);
A request to any other domain using the proxy works:
$username = 'user';
$password = 'pass';
$proxy = 'proxy:port';
$ch = curl_init('https://api64.ipify.org?format=json');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "$username:$password");
$result = curl_exec($ch); # returns the proxy ip
curl_close($ch);
But if I mix both, It doesn't work and a 403 error is returned by stripe api:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.stripe.com/v1/balance");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$a_pass");
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "$username:$password");
$out = curl_exec($ch);
if (curl_errno($ch)) {
print_r($curl_error($ch)); # 403
}
curl_close($ch);
It seems the CURLOPT_USERPWD is lost if the request is made using a proxy.
Any idea how to use a CURLOPT_PROXYUSERPWD, CURLOPT_PROXY and CURLOPT_USERPWD sucessfully on the same request?
Notes:
I cannot install any additional software on this machine.

How to browse website with Proxy in PHP

i want to fake my location in google analytics by surfing through proxy. i have created the script but the google analytics still show my real location.
The Script i am using is
<?php
$filename = "https://www.example.com";
$proxy = "103.250.147.22:8080";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $filename);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
?>
I think the proxy is not working or the code is not working? Can anyone tell me what i am doing wrong?

You can refer to this answer And about Google Analytics its hard to use a fake location
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;

PHP whois via proxy

$url = 'http://domain.com/helloworld/dimond/add';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);

How to use CURL via a proxy?

I am looking to set curl to use a proxy server. The url is provided by an html form, which has not been a problem. Without the proxy it works fine. I have found code on this and other sites, but they do not work. Any help in finding the correct solution would be much appreciated. I feel that the bellow are close, but that I am missing something. Thank You.
The bellow code I adapted from here http://www.webmasterworld.com/forum88/10572.htm but it returns an error message about a missing T_VARIABLE on line 12.
<?
$url = '$_POST[1]';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1)
curl_exec ($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
echo '<br />';
print_r($curl_info);
?>
The bellow is from curl through proxy returns no content
<?
$proxy = "66.96.200.39:80";
$proxy = explode(':', $proxy);
$url = "$_POST[1]";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);
$exec = curl_exec($ch);
echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
?>
is currently live on pelican-cement.com but also does not work.
UPDATE:
Thank you for all your help, I made the above changes. Now it only returns a blank screen.
<?
$url = $_POST['1'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_exec ($ch);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
?>

Here is a working version with your bugs removed.
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
I have added CURLOPT_PROXYUSERPWD in case any of your proxies require a user name and password.
I set CURLOPT_RETURNTRANSFER to 1, so that the data will be returned to $curl_scraped_page variable.
I removed a second extra curl_exec($ch); which would stop the variable being returned.
I consolidated your proxy IP and port into one setting.
I also removed CURLOPT_HTTPPROXYTUNNEL and CURLOPT_CUSTOMREQUEST as it was the default.
If you don't want the headers returned, comment out CURLOPT_HEADER.
To disable the proxy simply set it to null.
curl_setopt($ch, CURLOPT_PROXY, null);
Any questions feel free to ask, I work with cURL every day.

I have explained use of various CURL options required for CURL PROXY.
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url); // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy); // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth); // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1); // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;

Post declaring the proxy settings in the php script file issue has been fixed.

Here is a well tested function which i used for my projects with detailed self explanatory comments
There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server
function get_page($url){
global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce

curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding
$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
