PHP 日期加减的类，很不错

2018-12-30 PHP 前端之家

前端之家收集整理的这篇文章主要介绍了PHP 日期加减的类，很不错，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

如何使用这个类呢？请看下面的演示：
<div class="codetitle"><a style="CURSOR: pointer" data="31415" class="copybut" id="copybut31415" onclick="doCopy('code31415')"> 代码如下:

<div class="codebody" id="code31415">
$temptime = time();
echo strftime ( "%Hh%M %A %d %b",$temptime );
$date = new DateAccount();
$temptime = $date ->DateAdd( "n",50,$temptime );
echo "

" ;
echo strftime ( "%Hh%M %A %d %b",$temptime );

<div class="codetitle"><a style="CURSOR: pointer" data="23129" class="copybut" id="copybut23129" onclick="doCopy('code23129')"> 代码如下:

<div class="codebody" id="code23129">
$temptime = time();
echo strftime( "%Hh%M %A %d %b",$temptime);
$date = new DateAccount();
$temptime = $date->DateAdd("n",$temptime);
echo "

";
echo strftime( "%Hh%M %A %d %b",$temptime);

如果一切顺利，你可以看到以下结果：
15h41 Saturday 03 Jun
16h31 Saturday 03 Jun
<div class="codetitle"><a style="CURSOR: pointer" data="1103" class="copybut" id="copybut1103" onclick="doCopy('code1103')"> 代码如下:

<div class="codebody" id="code1103">
$currenttime = time();
echo "Current time: " . strftime ( "%Hh%M %A %d %b",$currenttime ). "
" ;
$date = new DateAccount();
$newtime = $date ->DateAdd ( "n",$currenttime );
echo "Time plus 50 minutes: " . strftime ( "%Hh%M %A %d %b",$newtime ). "
" ;
$temptime = $date ->DateDiff ( "n",$currenttime,$newtime );
echo "Interval between two times: " . $temptime ;

<div class="codetitle"><a style="CURSOR: pointer" data="40624" class="copybut" id="copybut40624" onclick="doCopy('code40624')"> 代码如下:

<div class="codebody" id="code40624">
$currenttime = time();
echo "Current time: ". strftime("%Hh%M %A %d %b",$currenttime)."
";
$date = new DateAccount();
$newtime = $date->DateAdd ("n",$currenttime);
echo "Time plus 50 minutes: ". strftime("%Hh%M %A %d %b",$newtime)."
";
$temptime = $date->DateDiff ("n",$newtime);
echo "Interval between two times: ".$temptime;

如果一切顺利，你可以看到以下结果：
Current time: 16h23 Saturday 03 Jun
Time plus 50 minutes: 17h13 Saturday 03 Jun
Interval between two times: 50
<div class="codetitle"><a style="CURSOR: pointer" data="22061" class="copybut" id="copybut22061" onclick="doCopy('code22061')"> 代码如下:<div class="codebody" id="code22061">
<?PHP
