</span><span><span class="hljs-keyword">echo</span></span><span> </span><span><span class="hljs-string">"<p>在 PHP 中，我们常常需要计算复活节的日期。PHP 提供了一个非常方便的函数 <code>easter_days()例如：
"; $year = 2025; $days_after_march21 = easter_days($year); echo "\$year = <span>$year</span></span></span><span>;\$days_after_march21 = easter_days(\$year);\n"; </span><span><span>echo</span></span><span> </span><span><span>"echo \$days_after_march21; // 输出 <span>$days_after_march21</span></span></span><span>"; echo "
我们可以利用 mktime 函数，将 3 月 21 日加上 easter_days 得到复活节的具体日期：
"; $easter_timestamp = mktime(0, 0, 0, 3, 21 + $days_after_march21, $year); echo "\$easter_date = date('Y-m-d', \$easter_timestamp);\n"</span></span><span>;
</span><span><span>echo</span></span><span> </span><span><span>"echo \$easter_date; // 输出 <span>$easter_date</span></span></span><span>";
echo "PHP 提供了丰富的日期格式化选项，例如：
"; $readable_date = date('l, F j, Y', $easter_timestamp); // 输出星期几, 月份名 日, 年份 echo "\$readable_date = date('l, F j, Y', \$easter_timestamp);\n"</span></span><span>;
</span><span><span>echo</span></span><span> </span><span><span>"echo \$readable_date; // 输出 <span>$readable_date</span></span></span><span>";
echo "这样，我们就能把复活节日期显示为类似 Sunday, April 20, 2025 的形式，让人一目了然。
"; echo "通过结合 easter_days() 和 date() 函数，我们可以：
