如何编码包含Unicode的网址？我想将它传递给命令行实用程序，我需要先对其进行编码。

<form action="index.php" method="get" >
<input type="text" name="find" value="عربي" /><br />
<input type="submit" value="search" />
<form />

实施例： http://localhost/index.php?find =عربي

变为http://localhost/index.php?find=%DA%D1%C8%ED

Answer 1

$ cat testme
#!/usr/local/bin/php
<?php

$chars = array( "d8", "b9", "d8", "b1", "d8", "a8", "d9", "8a" );

foreach ($chars as $one) {
    $string .= sprintf("%c", hexdec($one));
}

print "String: " . $string . "\n";
print "Encoded: " . urlencode($string) . "\n";

?>
$ ./testme
String: عربي
Encoded: %D8%B9%D8%B1%D8%A8%D9%8A
$

Answer 2

%DA%D1%C8%ED不是Unicode序列，而是其他编码中的URL编码序列。 URL编码后的Unicode中的عربي应变为%D8%B9%D8%B1%D8%A8%D9%8A

如果要构建具有Unicode字符的有效URL，可以使用以下内容：

$url = 'http://localhost/index.php?find=عربي';

$url_parts = parse_url($url);
$query_parts = array();
parse_str($url_parts['query'], $query_parts);
$query = http_build_query(array_map('rawurlencode', $query_parts));

$url_parts['query'] = $query;
$encoded_url = http_build_url($url_parts);

注意：这只会编码网址的query部分。

使用html表单进行URL编码
