PHP 中文处理技巧_PHP
折腾了一天的时间,才弄出点眉目来。
做AJAX应用或Flash应用,提交中文内容到后台,涉及到编码解码(encode、decode)及编码格式的转换。
网上的PHP端escape unescape函数建议不要用,它把中英文混合时的英文过滤掉了,我是莫名其妙了N久啊,建议用unicode_urldecode这个。
再就是编码格式的转换,这主要涉及数据的存储和客户端返回,用iconv就搞定,这个函数似乎是从C++中借鉴来的。
复制代码 代码如下:
function unicode_urldecode($url)
{
preg_match_all('/%u([[:alnum:]]{4})/', $url, $a);
foreach ($a[1] as $uniord)
{
$dec = hexdec($uniord);
$utf = '';
if ($dec {
$utf = chr($dec);
}
else if ($dec {
$utf = chr(192 + (($dec - ($dec % 64)) / 64));
$utf .= chr(128 + ($dec % 64));
}
else
{
$utf = chr(224 + (($dec - ($dec % 4096)) / 4096));
$utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64));
$utf .= chr(128 + ($dec % 64));
}
$url = str_replace('%u'.$uniord, $utf, $url);
}
return urldecode($url);
}

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
