增量 BR 标签计数器不工作，缺少某些内容

Question

我有以下代码，以便在每个BR标记旁边添加一个增量计数器，作为抒情歌曲的每行计数器，但它不起作用。需要帮助！

<?php $lyrics = "<p>Every time when I look in the mirror <br />All these lines on my face getting clearer <br /> The past is gone <br /> And it went by, like dusk to dawn <br /> Isn't that the way? <br /> Everybody's got their dues in life to pay <br /> Yeah, I know nobody knows <br /> Where it comes and where it goes <br /> I know it's everybody's sin <br /> You got to lose to know how to win <br /></p>";
$arr=explode(PHP_EOL, $lyrics);
foreach($arr as $index=>$ele)
{
echo $ele . $index+1 . "<br />";
} ?>

Answer 1

您正试图在PHP_EOL常量上拆分字符串$lyrics(这是一个依赖于平台的常量，指的是操作系统使用的行结束(。相反，您应该尝试按<br />拆分字符串。

Answer 2

这样尝试：使用"CCD_ 2"；分离并使每个回波单一：

$lyrics = "<p>Every time when I look in the mirror <br />All these lines on my face getting clearer <br /> The past is gone <br /> And it went by, like dusk to dawn <br /> Isn't that the way? <br /> Everybody's got their dues in life to pay <br /> Yeah, I know nobody knows <br /> Where it comes and where it goes <br /> I know it's everybody's sin <br /> You got to lose to know how to win <br /></p>";
$arr=explode("<br />", $lyrics);
foreach($arr as $index=>$ele)
{
echo $ele;
echo $index+1;
echo "<br />";
}
