我想从网页中提取歌词，所以我使用了strpos()和substr()，但是我只想在两个标签之间获取文本。
这是我的代码：
<?php
$homepage=file_get_contents("https://www.radiojavan.com/mp3s/mp3/Sahar-Ki-Asheghet-Karde");
$inja= htmlentities($homepage);
//echo strpos(htmlentities($homepage),"lyricsFars");
echo $tt= substr($inja,strpos($inja,"lyricsFars"),strpos($inja,"correct_lyrics_container"));
?>
我希望文本首先标记<div id="lyric_correction_container">，其结果是代码：
