我现在正在使用

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));

}

基本上，它对所有内容进行了rawurlencode，然后将一些内容解码回去(如Zanlok在他的评论中建议的那样).这应该符合Mozilla的encodeURI规范.

It basically rawurlencodes everything, and then decodes a few things back (as Zanlok suggested in his comment). This should conform to the Mozilla specs of encodeURI.
