今天的作业是完成一篇10000字的作文,那么这段代码瞬间就能帮助你完成。
至于老师能不能看懂,那不是我们关心的。

php代码

<?php
function unicode_decode($name) {
     
    // 转换编码,将Unicode编码转换成可以浏览的utf-8编码
    $pattern = '/([\w]+)|(\\\u([\w]{4}))/i';
    preg_match_all($pattern, $name, $matches);
    if (!empty($matches)) {
        $name = '';
        for ($j = 0; $j < count($matches[0]); $j++) {
            $str = $matches[0][$j];
            if (strpos($str, '\\u') === 0) {
                $code = base_convert(substr($str, 2, 2), 16, 10);
                $code2 = base_convert(substr($str, 4), 16, 10);
                $c = chr($code) . chr($code2);
                $c = iconv('UCS-2', 'UTF-8', $c);
                $name.= $c;
            } else {
                $name.= $str;
            }
        }
    }
    return $name;
}
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
} else {
    $str = "";
    for ($i = 0; $i < 100; $i++) {
        $str.= "\\u" . dechex(rand(19968, 40895));
    }
    $content.= unicode_decode($str);
}
