1 打印前一天时间
<?php
echo date("Y-m-d H:i:s", strtotime("-1 days"));
?>

2 过滤html代码
  如果此题单纯值的html代码，则 htmlspecialchars($str),处理输入存储
  如果包含用户输入过滤，则sql语句防注入，过滤关键词，使用pdo的时候prepare sql语句 ' 转义
  还有和谐社会的关键词过滤（这个非技术而属于政治了）
  php 原生 Filler 族函数能做相当一部分工作，可在此基础上扩展一个过滤类

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/local/mysql-5.6.13/bin/mysqladmin -u root password 'new-password'
  /usr/local/mysql-5.6.13/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:

1 php json_encode
假设encode编码的源数据是 ： array(1,2,3,4,5,5),那么json_encode的结果是数组
假设encode编码的源数据是：array(1=>1,2=>3),那么json_encode的结果是对象
json_encode默认把关联数组编码为对象
这个细节在和前端js交互传递数据的时候非常重要
