PHP http_build_url() and PECL Install
提问by PinoyStackOverflower
I downloaded an API that uses this php function http_build_url(). Everytime I run my application it says:
我下载了一个使用这个 php 函数 http_build_url() 的 API。每次我运行我的应用程序时，它都会说：
Fatal error: Call to undefined function http_build_url()
I made a research and found out that I should install pecl_http to run that function. Now, I installed it into my system, by the way, I used Windows XP. I install this one via CMD by goint to my xampp/php folder and running this command:
我进行了研究，发现我应该安装 pecl_http 来运行该功能。现在，我将它安装到我的系统中，顺便说一下，我使用的是Windows XP。我通过 CMD 安装到我的 xampp/php 文件夹并运行以下命令：
pecl install pecl_http
Unfortunately, I can't install this one because it says:
不幸的是，我无法安装这个，因为它说：
ERROR: The DSP pecl_http.dsp does not exist.
Is there a work around for this one? or any idea that I would make the http_build_url() run.
有没有办法解决这个问题？或者我会让 http_build_url() 运行的任何想法。

There is a work around. If you dont want or just cannot use PECL, then there is a method, mentioned on the php.net comments, which is a alternative method:
有一个解决办法。如果您不想或只是不能使用 PECL，那么在 php.net 评论中提到了一种方法，这是一种替代方法：
if (!function_exists('http_build_url'))
{
define('HTTP_URL_REPLACE', 1); // Replace every part of the first URL when there's one of the second URL
define('HTTP_URL_JOIN_PATH', 2); // Join relative paths
define('HTTP_URL_JOIN_QUERY', 4); // Join query strings
define('HTTP_URL_STRIP_USER', 8); // Strip any user authentication information
define('HTTP_URL_STRIP_PASS', 16); // Strip any password authentication information
define('HTTP_URL_STRIP_AUTH', 32); // Strip any authentication information
define('HTTP_URL_STRIP_PORT', 64); // Strip explicit port numbers
define('HTTP_URL_STRIP_PATH', 128); // Strip complete path
define('HTTP_URL_STRIP_QUERY', 256); // Strip query string
define('HTTP_URL_STRIP_FRAGMENT', 512); // Strip any fragments (#identifier)
define('HTTP_URL_STRIP_ALL', 1024); // Strip anything but scheme and host
// Build an URL
// The parts of the second URL will be merged into the first according to the flags argument.
//
// @param mixed (Part(s) of) an URL in form of a string or associative array like parse_url() returns
// @param mixed Same as the first argument
// @param int A bitmask of binary or'ed HTTP_URL constants (Optional)HTTP_URL_REPLACE is the default
// @param array If set, it will be filled with the parts of the composed url like parse_url() would return
function http_build_url($url, $parts=array(), $flags=HTTP_URL_REPLACE, &$new_url=false)
{
$keys = array('user','pass','port','path','query','fragment');
// HTTP_URL_STRIP_ALL becomes all the HTTP_URL_STRIP_Xs
if ($flags & HTTP_URL_STRIP_ALL)

$flags |= HTTP_URL_STRIP_PORT;
$flags |= HTTP_URL_STRIP_PATH;
$flags |= HTTP_URL_STRIP_QUERY;
$flags |= HTTP_URL_STRIP_FRAGMENT;

else if ($flags & HTTP_URL_STRIP_AUTH)
{
$flags |= HTTP_URL_STRIP_USER;
$flags |= HTTP_URL_STRIP_PASS;
}
// Parse the original URL
// - Suggestion by Sayed Ahad Abbas
// In case you send a parse_url array as input
$parse_url = !is_array($url) ? parse_url($url) : $url;
// Scheme and Host are always replaced
if (isset($parts['scheme']))

if ($flags & HTTP_URL_REPLACE)
{
foreach ($keys as $key)
{
if (isset($parts[$key]))
$parse_url[$key] = $parts[$key];
}
}
else
{
// Join the original URL path with the new path
if (isset($parts['path']) && ($flags & HTTP_URL_JOIN_PATH))
{
if (isset($parse_url['path']))
$parse_url['path'] = rtrim(str_replace(basename($parse_url['path']), '', $parse_url['path']), '/') . '/' . ltrim($parts['path'], '/');
else
$parse_url['path'] = $parts['path'];
}
// Join the original query string with the new query string
if (isset($parts['query']) && ($flags & HTTP_URL_JOIN_QUERY))
{
if (isset($parse_url['query']))
$parse_url['query'] .= '&' . $parts['query'];
else
$parse_url['query'] = $parts['query'];
}
}
// Strips all the applicable sections of the URL
// Note: Scheme and Host are never stripped
foreach ($keys as $key)
{
if ($flags & (int)constant('HTTP_URL_STRIP_' . strtoupper($key)))
unset($parse_url[$key]);
}
$new_url = $parse_url;
return
((isset($parse_url['scheme'])) ? $parse_url['scheme'] . '://' : '')
.((isset($parse_url['user'])) ? $parse_url['user'] . ((isset($parse_url['pass'])) ? ':' . $parse_url['pass'] : '') .'@' : '')
.((isset($parse_url['host'])) ? $parse_url['host'] : '')

.((isset($parse_url['query'])) ? '?' . $parse_url['query'] : '')
.((isset($parse_url['fragment'])) ? '#' . $parse_url['fragment'] : '')
;
}
}

Github 版本https://github.com/jakeasmith/http_build_url/blob/master/src/http_build_url.php
"This simple library provides functionality for http_build_url() to environments without pecl_http. It aims to mimic the functionality of the pecl function in every way and ships with a full suite of tests that have been run against both the original function and the one in this package."
“这个简单的库为没有 pecl_http 的环境提供了 http_build_url() 的功能。它旨在以各种方式模仿 pecl 函数的功能，并附带一整套测试，这些测试已经针对原始函数和本函数中的一个运行包裹。”
