我正在使用下面的代码打印 MP2 文件的 id3 标签，但输出以这种形式出现

Array ( [FileName] => 4.mp3 [TAG] => ID3 [Version] => 3.0 [Title] => &Bahut Khubsurat Ghazal (mr-Jatt.Com) [Album] => 1Loverz Choice (A Khubsurat Ghazal) (www.mzc.in) [Author] => DJ Badboy (mr-Jatt.Com) [Track] => (www.mzc.in) )

但我想要这样的简单输出

文件名 4.mp3 标题 Bahut Khubsurat Ghazal (mr-Jatt.Com) 专辑 1Loverz Choice (A Khubsurat Ghazal) (www.mzc.in) 作者 DJ Badboy (mr-Jatt.Com) 曲目 (www.mzc.in)

我的代码是

print_r(tagReader("4.mp3"));

这是因为您要返回一个数组。如果要打印出数组元素的内容，则必须遍历数组并打印每个元素，而不是返回整个数组。

就像是：

foreach ($results as $key => $value)
    echo $key . " " . $value;

你可以试试

foreach ( tagReader("4.mp3") as $name => $value ) {
    printf("<p>%s:%s</p>", $name, $value);
}
