php里encode,在PHP中的encodeURI()？

我现在使用这个

function encodeURI($url) {

// http://php.net/manual/en/function.rawurlencode.php

// https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/encodeURI

$unescaped = array(

'%2D'=>'-','%5F'=>'_','%2E'=>'.','%21'=>'!', '%7E'=>'~',

'%2A'=>'*', '%27'=>"'", '%28'=>'(', '%29'=>')'

);

$reserved = array(

'%3B'=>';','%2C'=>',','%2F'=>'/','%3F'=>'?','%3A'=>':',

'%40'=>'@','%26'=>'&','%3D'=>'=','%2B'=>'+','%24'=>'$'

);

$score = array(

'%23'=>'#'

);

return strtr(rawurlencode($url), array_merge($reserved,$unescaped,$score));

}

它基本上是对所有内容进行编码，然后再解码一些东西(正如Zanlok在他的评论中所建议的)。这应该符合encodeURI的Mozilla规范。
