PHP simple strtotime() time operation function_PHP tutorial

strtotime is the Unix timestamp of this time. Friends in need can simply refer to it. The getdate function is also mentioned in the middle, and then the hours, minutes, seconds, etc. can be output.

The code is as follows

代码如下

复制代码

//首先假设一个时间   $dt= "2010-09-06 11:19:56";   echo "时间：".$dt." ";   //将此时间格式化为Unix时间戳   $tm= strtotime($dt);   echo "此时间的Unix时间戳：".$tm." ";  ?> 实例 //用mktime()返回时间戳   $tm= mktime(23,56,59,12,20,1999);   echo "1999年12月20日23点56分59秒的Unix时间戳为：".$tm;   //用strtotime()返回时间戳   $tm2= strtotime("1999-12-20 23:56:59");   echo " 用strtotime获得的同一时间的时间戳：".$tm2;  ?> 二   //设置一个时间（如采用当前时间可用time()）   $tm = strtotime("2006-09-09 10:30:40");   echo "初始化设置的时间为：2006-09-09 10:30:40 ";   //使用不同的格式化字符串测试输出效果   echo date("Y-M-D H:I:S A",$tm)." ";   echo date("y-m-d h:i:s a",$tm)." ";   echo date("Y年m月d日[l] H点i分s秒",$tm)." ";   echo date("F,d,Y l",$tm)." ";   echo date("Y-M-D H:I:S",$tm)." ";   echo date("Y-M-D H:I:S",$tm)." ";   echo date("所在时区：T，与格林威治时间相差：O小时",$tm)." ";   //输出详细信息  ?>   //获取该时间的详细信息   $arr = getdate($tm);   //输出详细信息   echo "秒：".$arr["seconds"]." ";   echo "分：".$arr["minutes"]." ";   echo "时：".$arr["hours"]." ";   echo "日：".$arr["mday"]." ";   echo "月：".$arr["mon"]."/".$arr["month"]." ";   echo "年：".$arr["year"]." ";   echo "星期：".$arr["wday"]."/".$arr["weekday"]." ";   echo "该日期是该年中的第".$arr["yday"]."天 ";  ?>

Copy code

//First assume a time
$dt= "2010-09-06 11:19:56";
echo "Time:".$dt."
";
//Format this time as a Unix timestamp
$tm= strtotime($dt);
echo "The Unix timestamp of this time: ".$tm."
";
?>
Example

//Use mktime() to return the timestamp
$tm= mktime(23,56,59,12,20,1999);
echo "The Unix timestamp of 23:56:59 on December 20, 1999 is: ".$tm;
//Use strtotime() to return the timestamp
$tm2= strtotime("1999-12-20 23:56:59");
echo "
The timestamp of the same time obtained using strtotime:".$tm2;
?>

Two //Set a time (if the current time is used, time() can be used)
$tm = strtotime("2006-09-09 10:30:40");
echo "The initial setting time is: 2006-09-09 10:30:40
";
//Use different format strings to test the output effect
echo date("Y-M-D H:I:S A",$tm)."
";
echo date("y-m-d h:i:s a",$tm)."
";
echo date("Y year m month d day [l] H point i minute s second",$tm)."
";
echo date("F,d,Y l",$tm)."
";
echo date("Y-M-D H:I:S",$tm)."
";
echo date("Y-M-D H:I:S",$tm)."
";
echo date("Time zone: T, difference from Greenwich Mean Time: O hours",$tm)."
";
//Output detailed information
?> //Get detailed information about the time
$arr = getdate($tm);
//Output detailed information
echo "Seconds:".$arr["seconds"]."
";
echo "Minutes:".$arr["minutes"]."
";
echo "hours:".$arr["hours"]."
";
echo "Day:".$arr["mday"]."
";
echo "Month:".$arr["mon"]."/".$arr["month"]."
";
echo "Year:".$arr["year"]."
";
echo "Weekday:".$arr["wday"]."/".$arr["weekday"]."
";
echo "The date is the ".$arr["yday"]."day
";
?>
