How to have PHP to use Proxy Setting to connect to internet?

Question

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.

Answer 1

if almost all of you internet access need a proxy, I'd prefer do like this.

//add this as the first line of the entry file may it is the index.php or config.php stream_context_set_default(['http'=>['proxy'=>'proxy-host:proxy-port']]); 

the proxy will work for file_get_contents but not curl_exec

here is a official document.

Answer 2

This depends on how your PHP application connects to the internet.

If taking the most likely situation using PHP cUrl. In that case the following options will help you:

curl_setopt($handle, CURLOPT_PROXY, $proxy_url);  curl_setopt($handle, CURLOPT_PROXYUSERPWD, "[username]:[password]");
