使用PHP date()函数。

格式是Y，大写的Y是四位数的年份。

<?php echo date("Y"); ?>

创建一个helper函数并调用它

getCurrentYear();

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

<?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

全年使用:

 <?php 
    echo $curr_year = date('Y'); // it will display full year ex. 2017
?>

或者只得到两位年份，就像这样:

 <?php 
    echo $curr_year = date('y'); // it will display short 2 digit year ex. 17
?>

$dateYear = date('Y');
echo "Current Year: $dateYear";

本年:2022年

$dateYear = date('y');
echo $dateYear;

22

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.
