创建一个helper函数并调用它

getCurrentYear();

function getCurrentYear(){
    return now()->year;
}

$year = date("Y", strtotime($yourDateVar));

print date('Y');

有关更多信息，请查看date()函数文档:https://secure.php.net/manual/en/function.date.php

<?php date_default_timezone_set("Asia/Kolkata");?><?=date("Y");?>

你可以在页脚部分使用它来获得动态版权年份

我显示版权的方式，它会自动更新

<p class="text-muted credit">Copyright &copy;
    <?php
        $copyYear = 2017; // Set your website start date
        $curYear = date('Y'); // Keeps the second year updated
        echo $copyYear . (($copyYear != $curYear) ? '-' . $curYear : '');
    ?> 
</p>    

它将输出结果为

copyright @ 2017   //if $copyYear is 2017 
copyright @ 2017-201x    //if $copyYear is not equal to Current Year.

我是这么做的:

<?php echo date("d-m-Y") ?>

下面是对它功能的一些解释:

d = day
m = month
Y = year

Y表示四位数(如1990)，Y表示两位数(如90)
