php discuz中使用的加密解密算法

有时我们需要使用PHP将特定的信息进行加密，也就是通过加密算法生成一个加密字符串，这个加密后的字符串可以通过解密算法进行解密，便于程序对解密后的信息进行处理。最常见的应用在用户登录以及一些API数据交换的场景。最常见的应用在用户登录以及一些API数据交换的场景。加密解密原理一般都是通过一定的加密解密算法，将密钥加入到算法中，最终得到加密解密结果。

php php在操作断点续传时文件如何分割合并

php实现断点续传，就需要把大文件分割成多个小文件，然后单个上传。传完后在合并。<br/> $ b $b│merge.php - 合并文件脚本\ <br/>│合并.zip - 合并后文件\ $ b $b│socket.zip - 需要分割的文件\ $ b $b│split.php - 分割文件脚本\ $ b $b│\ <br/>└─split - 分割后小文件目录

split.php

<?php

  fwrite($fp2, $file, $filesize);
  fclose($fp2);
