PHP levels are 0 (writes messages and errors to logs), 1 (shows proxy errors and messages in browser console), 2 (combination of levels 0 and 1), and 3 (no logging); the default is 0. Add a new entry for each service that will use the proxy. We would like to show you a description here but the site won’t allow us. Nov 27, 2019 PHP Proxy is described as 'To bypass restricted sites' and is an app in the Development category. There are eight alternatives to PHP Proxy for a variety of platforms, including the Web, Self-Hosted solutions, PHP, cURL and Windows. The best alternative is Glype, which is free.
Php Proxy Server
Setting a proxy server to be used with cURL and PHP is relatively simple, it mostly depends on the server that you are using, and authentication method (if any). The HTTP authentication method is controlled with the CURLOPT_PROXYAUTH option, the default method is CURLAUTH_BASIC – if the proxy requires authentication, a username and password can be set in the [username]:[password] format, using the CURLOPT_PROXYUSERPWD option.
For now we'll just focus on using a proxy that doesn't require any authentication. Setting a proxy server and a port number in PHP for cURL can be done using the CURLOPT_PROXY option, like shown in the below example:
As shown in the above example, you can set the a proxy with the IP:PORT syntax in PHP using cURL. But if you prefer to keep the ip seperated from the port, you can also use the CURLOPT_PROXYPORT option, which would result in the below PHP code:
I'm behind a proxy server that does not allow a direct connection to internet. All of my PHP applications fail to connect to internet for their update checks and etc. How can I tell PHP my Proxy Settings? I don't want to enter proxy settings into the code, I want PHP itself use it via a global config setting or something similar. A great technique for detecting proxies with PHP is to test for HTTP proxy headers that are commonly passed by users behind a proxy or VPN connection. The example code below provides a quick test that can be performed with PHP code to detect if the user has an HTTP header value that is commonly associated with a proxy connection.
After setting a proxy server, you will be able to perform the request using the curl_exec function. I.e.
Setting cURL Proxy Type
cURL supports two proxy types, the default is HTTP, and the other option is SOCKS5. You can set the proxy type using the CURLOPT_PROXYTYPE option. I.e.
You really only need to set the type of the proxy, if you are not using a HTTP proxy.
Php Proxy Server Scripts
Setting Authentication Method
As mentioned in the beginning of the tutorial, setting the authentication method of a proxy server can be done using the CURLOPT_HTTPAUTH option. To make this work properly, we will also need to provide a username and password for the proxy server, this is all accomplished in the below script, in which we are just using a BASIC authentication method.
Other authentication methods include the following:

Note.The vertical bar (or) operator can be used to combine methods. If this is done, cURL will poll the server to see what methods it supports and pick the best.
You can use the following API endpoints for testing purposes:
Scripts comprising a PHP proxy can be written in two ways. First, they can be written as a sequence of commands, to be executed one after the other. Second, they can be structured like classes in an object-oriented programming language. Either type of PHP script can be included inside other PHP scripts to minimize repeated code throughout the proxy.
Since a PHP proxy is run on the Internet, there are many security issues that should be taken into account when writing one. PHP proxies must not only transfer data from a web page to a server, they must also check the data given on the web page to ensure that the data will not negatively impact the server. The PHP scripting language has some built-in functions that allow for proper validation and sanitation of input, but these alone cannot always protect a server from a malicious attack. Proper error checking of input and proper structuring of the scripts within the PHP proxy are essential.
When a PHP proxy consists of multiple scripts, each script should have some form of error checking and input validation. Even if a PHP script doesn't take input directly from a web page, it may still be possible for a user, innocent or malicious, to run the script from the Internet in contexts when it shouldn't be. There exist in the PHP language both built-in methods and small algorithms the developer can implement to prevent this unauthorized execution. Foolproofing PHP scripts in this manner does not necessarily entail specific provisions in each script to prevent access from every other script as well as the Internet. Often, simple mechanisms can be used that protect scripts from most common attacks. Get shutter count canon.
PHP proxies allow web pages to have wide functionality beyond static text and images. While validation of forms is by far the most common functionality, PHP can also be used to create dynamic images or directly call programs to generate results from data. Each distinct use of PHP has its own set of security concerns, and one should take great care to balance functionality with safety in a PHP proxy.
