encodeURI()在PHP？

Question

在PHP中是否有一些不编码的encodeURI()函数:~!@#$&*()=:/,;?+'？

Answer 1

我现在正在使用它

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rawurlen编码,然后将一些内容解码回来(正如Zanlok在他的评论中所建议的那样).这应该符合encodeURI的Mozilla规范.

这是基于MDN规范的备用版本:

function encodeURI($uri)
{
    return preg_replace_callback("{[^0-9a-z_.!~*'();,/?:@&=+$#-]}i", function ($m) {
        return sprintf('%%%02X', ord($m[0]));
    }, $uri);
}
