Question

我使用下面的代码打印MP2文件的id3标签，但输出是以这种形式出现的

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) )

但我想要像这样的简单输出

FileName 4.mp3 Title Bahut Khubsurat Ghazal（mr-Jatt.Com）专辑1Loverz Choice（A Khubsurat Ghazal）（www.mzc.in）作者DJ Badboy（mr-Jatt.Com）Track（www.mzc.in））

我的代码是

print_r(tagReader("4.mp3"));
// ------------------------------
function tagReader($file) {
    $id3v23 = array("TIT2","TALB","TPE1","TRCK","TDRC","TLEN","USLT");

    $fsize = filesize($file);
    $fd = fopen($file, "r");
    $tag = fread($fd, $fsize);
    $tmp = "";
    fclose($fd);
    if (substr($tag, 0, 3) == "ID3") {
        $result['FileName'] = $file;
        $result['TAG'] = substr($tag, 0, 3);
        $result['Version'] = hexdec(bin2hex(substr($tag, 3, 1))) . "." . hexdec(bin2hex(substr($tag, 4, 1)));
    }
    if ($result['Version'] == "4.0" || $result['Version'] == "3.0") {
        for($i = 0; $i < count($id3v23); $i ++) {
            if (strpos($tag, $id3v23[$i] . chr(0)) != FALSE) {
                $pos = strpos($tag, $id3v23[$i] . chr(0));
                $len = hexdec(bin2hex(substr($tag, ($pos + 5), 3)));
                $data = substr($tag, $pos, 9 + $len);
                for($a = 0; $a < strlen($data); $a ++) {
                    $char = substr($data, $a, 1);
                    if ($char >= " " && $char <= "~")
                        $tmp .= $char;

Answer 1

这是因为你要返回一个数组。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。

类似的东西：

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

Answer 2

你可以尝试

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

打印输出问题
