More than 1 year has passed since last update.

PECLのhttp_build_urlとの互換性はありません。


関数定義

function build_url(array $elements) {

$e = $elements;
return
(isset($e['host']) ? (
(isset($e['scheme']) ? "$e[scheme]://" : '//') .
(isset($e['user']) ? $e['user'] . (isset($e['pass']) ? ":$e[pass]" : '') . '@' : '') .
$e['host'] .
(isset($e['port']) ? ":$e[port]" : '')
) : '') .
(isset($e['path']) ? $e['path'] : '/') .
(isset($e['query']) ? '?' . (is_array($e['query']) ? http_build_query($e['query'], '', '&') : $e['query']) : '') .
(isset($e['fragment']) ? "#$e[fragment]" : '')
;
}


例 (コード)

<?php

$patterns = [
['host' => 'example.com'],
['scheme' => 'https', 'host' => 'example.com'],
['scheme' => 'http', 'host' => 'example.com', 'port' => 8080, 'path' => '/x/y/z'],
['scheme' => 'http', 'host' => 'example.com', 'port' => 8080, 'user' => 'anonymous', 'query' => 'a=b&c=d', 'fragment' => 'xyz'],
['scheme' => 'http', 'host' => 'example.com', 'user' => 'root', 'pass' => 'stupid', 'path' => '/x/y/z', 'query' => ['a' => 'b', 'c' => 'd']],
['path' => '/x/y/z', 'query' => 'a=b&c=d'],
];

foreach ($patterns as $pattern) {
echo json_encode($pattern, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES) . "\n/* " . build_url($pattern) . " */\n\n";
}
