PHP 跟 Javascript 都有 HTML encoding 的函式,编码过的结果虽然类似,但是还是有些微的不同,所以不能互转。 二者的差异可以可参考:http://php.weblogs.com/php_jscript_vbscript_1节录如下:PHP:urlencode( ) All punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding. Spaces converted to +.urldecode( )All punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding. Spaces converted to +.Javascript:Javascript(str) All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding那要如何用 PHP 来读取 escape() 编码过的字符串呢?可以用以下的方式来读取 (范例为 Unicode 解译为 big5)修改自:http://vivian.stripper.jp/index.php?itemid=100$str = uniDecode($str,'big-5'); function uniDecode($str,$charcode){
$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/",toUtf8,$str);
return mb_convert_encoding($text, $charcode, 'utf-8');
}
function toUtf8($ar){
foreach($ar as $val){
$val = intval(substr($val,2),16);
if($val < 0x7F){ // 0000-007F
$c .= chr($val);
}elseif($val < 0x800) { // 0080-0800
$c .= chr(0xC0 | ($val / 64));
$c .= chr(0x80 | ($val % 64));
}else{ // 0800-FFFF
$c .= chr(0xE0 | (($val / 64) / 64));
$c .= chr(0x80 | (($val / 64) % 64));
$c .= chr(0x80 | ($val % 64));
}
}
return $c;
}
