PHP conversion between timestamp and date _php tutorial

There are many ways to express time and date in PHP, the most common is the time stamp and the normal date format, let me introduce the time stamp and the date conversion.

1.php Time conversion function

Strtotime

The strtotime () function resolves the datetime description of any English text to a Unix timestamp.

Grammar
Strtotime (Time,now)

Cases

The code is as follows	Copy Code
Strtotime ("Today")

Date

The PHP date () function formats the timestamp as a date and time that is more readable.

Grammar
Date (Format,timestamp)

Cases

The code is as follows	Copy Code
echo Date ("y/m/d"); echo " "; echo Date ("Y.M.D"); echo " "; echo Date ("y-m-d"); ?>

Convert Timestamp to date

The code is as follows	Copy Code
Date ("Y-m-d h:i", $unixtime)

Get a timestamp of today's 0 points in 2.php

To get a 0-point Unix timestamp, you can use $todaytime=strtotime ("Today"),

Then use Date ("Y-m-d h:i", $todaytime) to convert to a date.

3.php timestamps are converted to dates and display different content by time, such as just, minutes ago, hours ago, today, yesterday, etc.

/* Time conversion function */

The code is as follows

Copy Code

function Transtime ($ustime) { $ytime = Date ("y-m-d h:i", $ustime); $rtime = Date ("N-month J-day H:i", $ustime); $htime = Date ("H:i", $ustime); $time = Time ()-$ustime; $todaytime = Strtotime ("Today"); $time 1 = time ()-$todaytime; if ($time < 60) { $str = ' just '; }else if ($time < 60 * 60) { $min = Floor ($time/60); $str = $min. ' Minutes ago '; }else if ($time < $time 1) { $str = ' Today '. $htime; }else{ $str = $rtime; } return $str; }

In this function you can add more comparisons to make the displayed date more specific, such as adding seconds before the day before, and so on more specific dates.

4.php date in 0 and do not fill 0

echo Date (' y-m-d '); Show 2012-08-08

echo Date (' y-n-j '); Show 2012-8-8
