Introduction

This article introduces the use of Date in PHP and JS.

Detailed introduction

The difficulty encountered today is Date outputting the time in 24-hour format. Regarding this weak link, make a simple note.

PHP Date()

php date() Method to output 24-hour time: echo date("Y-m-d H:i:s");
Method to output 12-hour time: echo date("y-m-d h:i:s");
The main difference between uppercase and lowercase is completeness, for example, H and h - corresponding to the 24/12 hour clock.

The following code:

<code><span>echo</span> date(<span>"Y-m-d H:i:s"</span>).<span>"<br />"</span>;
<span>echo</span> date(<span>"y-m-d h:i:s"</span>);</code>

The output to the browser is:

<code>2014<span>-03-01</span> 14<span>:09</span><span>:15</span>
14<span>-03-01</span> 02<span>:09</span><span>:15</span></code>

JS Date()

JS object used to process time, including various methods of processing time, simple and easy to implement.
Code block of commonly used methods:

<code><span>//①：</span>
document.write(<span>Date</span>())

<span>var</span> d=<span>new</span><span>Date</span>()
<span>var</span> day=d.getDate()
<span>var</span> m + <span>1</span><span>//注：该方法返回0~11</span><span>var</span> year=d.getFullYear()
<span>//②</span>
