Question

可能重複：
What is best solution to get next and previous month from given date php

我開發PHP中的工作。在這裏，我想下一個和上月從某月例如：

$mth="December"

我想提前

感謝

Answer 1

$mth="December"; 
$next_mth = Date("F", strtotime($mth . " next month")); 
$pre_mth = Date("F", strtotime($mth . " last month")); 

Answer 2

這應該做月的下一個和以前顯示：

$date = new DateTime(); 
$date->modify('+ 1 month'); 
print $date->format("F"); // next 
$date->modify('- 2 month'); 
print $date->format("F"); // previously 

Answer 3

看看這個也得到這些東西的方法

$mth="December"; 

$nxt = date('F',mktime(0,0,0,date("m", strtotime($mth))+2,null,null)); 
$pre = date('F',mktime(0,0,0,date("m", strtotime($mth))-0,null,null)); 
echo $pre.'-'.$mth.'-'.$nxt;
