Why PHP_EOL does not work or is invalid

PHP_EOL is a text line break, not an html line break.

Add echo "

";<p> for text formatting, </p><p>The PHP_EOL at the end will work.</p><pre class="brush:php;toolbar:false"><?php
echo "<pre class="brush:php;toolbar:false">";
//字符串
//第1种表示
$date = &#39;2020-02-10&#39;;
echo $date . PHP_EOL;

$date = "2020-02-10";
echo $date . PHP_EOL;
//第3种表示---用于内容非常多的情况
$date = <<<DATE
2020-02-10
DATE;
echo $date . PHP_EOL;
//第4种表示---用于内容非常多的情况
$date = <<<&#39;DATE&#39;
