php - 简单的日期函数在 php 中不起作用

Question

<?php

$year = '2017';
$week = '2';
echo date( "F jS", strtotime($year."W".$week."0"));                         
?>

我没有得到预期的结果；我想要 Sun 8th，但我得到了 May 15th。

我做错了什么？

Answer 1

试试这个，

$year = "2017"; 
$week = "02"; // Week number must be two digit
$date1 = date( "l, M jS, Y", strtotime($year."W".$week."0") ); // First day of week    
echo $date1;

输出

Sunday, Jan 8th, 2017
