PEAR和PHP —升级/执行任何操作时，OS X上的“获取频道信息时出错”
[英]PEAR and PHP — “Error getting channel info” on OS X when upgrade/do anything
问题描述
I saw this question: Problem with update pear that said the issue is using an outdated version of PEAR, well, I'm using 1.9.4(the latest). 
我看到了一个问题： 更新pear的问题是该问题使用的是PEAR的过时版本，嗯，我使用的是1.9.4（最新版本）。
dinosaurhunter:~ root# pear -V
PEAR Version: 1.9.4
PHP Version: 5.3.21
Zend Engine Version: 2.3.0
Running on: Darwin dinosaurhunter.network.local 12.2.1 Darwin Kernel Version 12.2.1: Thu Oct 18 16:32:48 PDT 2012; root:xnu-2050.20.9~2/RELEASE_X86_64 x86_64
I am using PHP from homebrew. 我正在使用自制软件的PHP。
So weird: 太奇怪了：
dinosaurhunter:~ root# pear upgrade
Error getting channel info from pear.php.net: Connection to `pear.php.net:80' failed: Operation timed out
Error getting channel info from pear.php.net: Connection to `pear.php.net:80' failed: Operation timed out

Nothing to upgrade

I saw some people saying it's a proxy thing -- I don't use a proxy either. 我看到有人说这是代理人的事-我也不使用代理人。
dinosaurhunter:~ root# pear config-show | grep -i proxy
HTTP Proxy Server Address http_proxy <not set>
I'm really lost because the URLs they say are timing out work just fine, I'm not using a proxy, PEAR is up to date -- what else could it be? 我真的迷失了，因为他们说的超时URL可以正常工作，我没有使用代理，PEAR是最新的-还能是什么？
EDIT did more debugging... EDIT进行了更多调试...
This code works: 此代码有效：
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set ('allow_url_fopen', 1);
$url = 'http://www.google.com';
// Create a stream
$opts = array(
'http'=>array(
'timeout'=>60,
)
);
$context = stream_context_create($opts);
// Open the file using the HTTP headers set above
$file = file_get_contents($url, false, $context);
var_dump($file);
However, this doesn't work: 但是，这不起作用：
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set ('allow_url_fopen', 1);
$file = file_get_contents('http://www.google.com/');
var_dump($file);
It fails with: 它失败并显示：
Warning:
file_get_contents(http://www.google.com/): failed to open stream: Operation timed outfile_get_contents(http://www.google.com/)：无法打开流：操作超时

The underlying issue wound up being the default_socket_timeout configuration. 根本的问题是default_socket_timeout配置。
It was set like: 设置为：
; Default timeout for socket based streams (seconds)
; http://php.net/default-socket-timeout
default_socket_timeout = unlimited
I changed it to 我将其更改为
; Default timeout for socket based streams (seconds)
; http://php.net/default-socket-timeout
default_socket_timeout = 120
and it works. 而且有效。
It looks like file_get_contents might not respect a default_socket_timeout value of "unlimited". 看起来file_get_contents可能不尊重default_socket_timeout值“ unlimited”。 Blargh! lar！

Run wireshark and check what pear actually does network-wise. 运行wireshark，并检查梨实际上是从网络角度执行的。 You can also run pear -vvvvvv to get debug output - that might give you a hint about the problem source. 您还可以运行pear -vvvvvv以获得调试输出-可能会提示您有关问题的根源。
