本文实例讲述了PHP使用strtotime计算两个给定日期之间天数的方法。分享给大家供大家参考。具体分析如下:

PHP的strtotime函数用于将任何英文文本的日期时间描述解析为Unix时间戳。这个函数将使用TZ环境变量(如果有的话)来计算时间戳。如果执行成功它返回一个时间戳,否则返回FALSE。在PHP 5.1.0之前,这个函数将返回-1。

$date1 = date('Y-m-d');
$date2 = '2005-03-01′;
$days = (strtotime() – strtotime()) / (60 * 60 * 24);
echo "Number of days since '2005-03-01′: $days";
Copy after login

希望本文所述对大家的php程序设计有所帮助。
