xml.php 生成要同步的源码up_xml.php这代码也是看某个博客在线安装的，挺好用的，可以自己在更新网站代码上使用，不用一个个的去上传

PHP用的配置文件，直接写到目录，安全就不知道了

<?php $str = 'hello word';$arr = array();for($i=0;$i<strlen($str);$i++){ $arr[] = ord($str{$i});}$chars = array_map("chr", $arr);$bin = join($chars);$hex = bin2hex($bin);print_r($hex);exit;调试输出 (字节集_字节集到十六进制 (到字节集 (“hello word”)))“字.

function rc4 ($pwd, $data) { $key[] =""; $box[] =""; $pwd_length = strlen($pwd); $data_length = strlen($data); for ($i = 0; $i < 256; $i++) { $key[$i] = ord($pwd[$i % $pwd_length]); $box[$i] = $i; }

这两天，我的API数据量百万，查询速度3.2秒select id,u,p from qq where code=0 ORDER BY id DESC limit 1刚开始用的这么一段代码，服务器的CPU直接就崩溃了！改了一下不加ORDER BY id DESC速度0.1几秒select id,u,p from qq where code=0 limit 1但是这样查是按的从小查起，要的不是这样后面这样改了一下，速度从3秒直接到了0.7秒，快了不少select id,u,p from qq w
