Conversion program between timestamp and date in PHP_PHP tutorial

There are many ways to express time and date in PHP. The most commonly used ones are timestamp and ordinary date format. Let me introduce the conversion between timestamp and date.

Time conversion function in 1.php

strtotime

The

strtotime() function parses any English text datetime description into a Unix timestamp.

Grammar
strtotime(time,now)

Example

The code is as follows	Copy code
代码如下 复制代码 strtotime(“today”) strtotime(“today”)

date

The PHP Date() function can format the timestamp into a more readable date and time.

Grammar

date(format,timestamp)

Example

代码如下	复制代码
echo date("Y/m/d"); echo " "; echo date("Y.m.d"); echo " "; echo date("Y-m-d"); ?>

The code is as follows	Copy code
echo date("Y/m/d");  代码如下 复制代码 date("Y-m-d H:i",$unixtime) 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 today’s zero time timestamp in 2.php

To get the unix timestamp at zero point, you can use $todaytime=strtotime("today"),

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

Convert the timestamp in 3.php to date, and display different contents according to time, such as just now, minutes ago, hours ago, today, yesterday, etc.

/*Time conversion function*/

$time1 = time() - $todaytime;

The code is as follows  代码如下 复制代码 function transTime($ustime) {            　　$ytime = date("Y-m-d H:i",$ustime);              　　$rtime = date("n月j日 H:i",$ustime);            　　$htime = date("H:i",$ustime);            　　$time = time() - $ustime;            　　$todaytime = strtotime("today");            　　$time1 = time() - $todaytime;                            　　if($time < 60){                    　　　　$str = '刚刚';            　　}else if($time < 60 * 60){                             　　　　$min = floor($time/60);                    　　　　$str = $min.'分钟前';            　　}else if($time < $time1){                    　　　　$str = '今天 '.$htime;            　　}else{                    　　　　$str = $rtime;            　　}              　　return $str; }

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");

if($time < 60){                                                         　　$str = 'Just now'; 　　　　　　

　}else if($time < 60 * 60){
