XAMPP (Windows) 上的 PECL 扩展安装

Question

我需要一些帮助，我已经尝试过了，但还没有想到要赢。

我需要在 XAMPP(v7.4.5) 上获取 ID3 PECL 运行 Windows。

我昨天花了一天时间尝试浏览 PHP.net 网站上的 PECL articles ，不幸的是，这对我来说意义不大，因为我的知识还没有达到那个水平。我也曾尝试为 ID3 扩展寻找一个 dll 文件，但找不到任何文件。 ID3 PECL 页面只有源文件可供下载。

是否有足够耐心的人可以用更通俗易懂的术语解释这个过程...为我简化一下？

我们将不胜感激任何帮助。

有人可以帮忙吗？

在 Lelio 的帮助下，我现在有办法从 MP3 中提取信息，我添加了两行来访问 Genre 以及 Attached图片 块。流派块有效。然而，附加图片 块没有。

这是更新后的代码，保存为单独的 php 文件，名为 script-mp3-tag-reader.php:

<?php
    function tagReader($file)
    {
        $id3v23 = array("TIT2","TALB","TPE1","TRCK","TDRC","TLEN","USLT","TCON","APIC");
        $id3v22 = array("TT2","TAL","TP1","TRK","TYE","TLE","ULT","TCO");
        $fsize = filesize($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;
                        }
                    }
                    if(substr($tmp,0,4) == "TIT2") $result['Title'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "TALB") $result['Album'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "TPE1") $result['Artist'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "TRCK") $result['TrackNo'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "TDRC") $result['Year'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "TLEN") $result['Lenght'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "USLT") $result['Lyric'] = substr($tmp,7);
                    if(substr($tmp,0,4) == "TCON") $result['Genre'] = substr($tmp,4);
                    if(substr($tmp,0,4) == "APIC") $result['AttachedPicture'] = substr($tmp,4);
                    $tmp = "";
                }
            }
        }
        if($result['Version'] == "2.0")
        {
            for ($i=0;$i<count($id3v22);$i++)
            {
                if (strpos($tag,$id3v22[$i].chr(0))!= FALSE)
                {
                    $pos = strpos($tag, $id3v22[$i].chr(0));
                    $len = hexdec(bin2hex(substr($tag,($pos+3),3)));
                    $data = substr($tag, $pos, 6+$len);
                    for ($a=0;$a<strlen($data);$a++)
                    {
                        $char = substr($data,$a,1);
                        if($char >= " " && $char <= "~")
                        {
                            $tmp.=$char;
                        }
                    }
                    if(substr($tmp,0,3) == "TT2") $result['Title'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "TAL") $result['Album'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "TP1") $result['Artist'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "TRK") $result['TrackNo'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "TYE") $result['Year'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "TLE") $result['Lenght'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "ULT") $result['Lyric'] = substr($tmp,6);
                    if(substr($tmp,0,3) == "TCO") $result['Genre'] = substr($tmp,3);
                    if(substr($tmp,0,3) == "PIC") $result['AttachedPicture'] = base64_encode(substr($tmp,3));
                    $tmp = "";
                }
            }
        }
        return $result;
    }
?>

然后在我的 index.php 文件中加载并使用上面的 PHP 脚本，如下所示：

<?php
    require_once($_SERVER['DOCUMENT_ROOT'].'/script/php/script-mp3-tag-reader.php');
    $mp3 = $_SERVER['DOCUMENT_ROOT'].'/media/audio/mp3/test_audio.mp3';
    $myResult = tagReader($mp3);
    print_r($myResult);
?>

当查看 print_r($myresult); 时，可以看到信息确实存在并且是正确的...只是不是附件图像部分。我似乎正在提取远远超过需要的东西，并且不知道如何只访问我需要的东西。

像这样的东西应该可以解决问题。它最近没有经过测试，但应该可以从 mp3 文件中读取您要查找的数据。

function tagReader($file){
    $id3v23 = array("TIT2","TALB","TPE1","TRCK","TDRC","TLEN","USLT");
    $id3v22 = array("TT2","TAL","TP1","TRK","TYE","TLE","ULT");
    $fsize = filesize($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;
                }
                if(substr($tmp,0,4) == "TIT2") $result['Title'] = substr($tmp,4);

                if(substr($tmp,0,4) == "USLT") $result['Lyric'] = substr($tmp,7);
                $tmp = "";
            }
        }
    }
    if($result['Version'] == "2.0"){
        for ($i=0;$i<count($id3v22);$i++){
            if (strpos($tag,$id3v22[$i].chr(0))!= FALSE){
                $pos = strpos($tag, $id3v22[$i].chr(0));
                $len = hexdec(bin2hex(substr($tag,($pos+3),3)));
                $data = substr($tag, $pos, 6+$len);
                for ($a=0;$a<strlen($data);$a++){
                    $char = substr($data,$a,1);
                    if($char >= " " && $char <= "~") $tmp.=$char;
                }
                if(substr($tmp,0,3) == "TT2") $result['Title'] = substr($tmp,3);
                if(substr($tmp,0,3) == "TAL") $result['Album'] = substr($tmp,3);
                if(substr($tmp,0,3) == "TP1") $result['Author'] = substr($tmp,3);
                if(substr($tmp,0,3) == "TRK") $result['Track'] = substr($tmp,3);
