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_PROXYUSERPWD, "[username]:[password]");

For Drupal you can set proxy configuration in your settings.php file.

<code>$conf['proxy_server']</code> and so on.

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

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

the proxy will work for <code>file_get_contents</code> but not <code>curl_exec</code>

blocks|key|1122823|text|对于某些脚本，您所要做的就是设置环境变量HTTP_PROXY。这就是composer.phar和媒体维基的维护/update.php脚本的情况。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1122824|例如：|1122825|setenv+HTTP_PROXY+http://1.2.3.4:3934|code-block|syntax|javascript|1122826|如果您的代理在端口3934上侦听1.2.3.4。对我很管用。|1122827|entityMap^0|K|A|Y|D|1K|A|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|Y|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|Z|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

For some scripts, all you have to do is set the environment variable <code>HTTP_PROXY</code>. That was the case for both <code>composer.phar</code> and media-wiki's maintenance/<code>update.php</code> scripts.

E.g.:

<pre><code>setenv HTTP_PROXY http://1.2.3.4:3934
</code></pre>

If your proxy is at 1.2.3.4 listening on port 3934. Worked for me.

Yes it's possible!

You can configure <code>stream_context_set_default</code> in a file, and include this file in all your Php program, by using <code>auto_prepend_file</code> php.ini property.

I wrote a small gist about:

<a href="https://gist.github.com/ebuildy/381f116e9cd18216a69188ce0230708d" rel="nofollow noreferrer">https://gist.github.com/ebuildy/381f116e9cd18216a69188ce0230708d</a>

And an article in french:

<a href="https://medium.com/@thomasdecaux/param%C3%A9trer-par-d%C3%A9faut-un-proxy-pour-php-file-get-content-3e9a32416979#.6zbg605cx" rel="nofollow noreferrer">https://medium.com/@thomasdecaux/param%C3%A9trer-par-d%C3%A9faut-un-proxy-pour-php-file-get-content-3e9a32416979#.6zbg605cx</a>

This technique is "cool" because, this allows your sys-admin to configure the host, so developer don't have to change anything in the 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.

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

服务器

Drupal

我在一个不允许直接连接到互联网的代理服务器后面。我所有的PHP应用程序都无法连接到互联网进行更新检查等。我如何告诉PHP我的代理设置？我不想在代码中输入代理设置，我希望PHP自己通过全局配置设置或类似的设置来使用它。
