php - php 在文本文件中搜索任何 wav 文件名

Question

我有一系列包含原始文本或 json 数据的文件，在这些文件中将是 wav 文件名。所有 wav 文件的后缀为.wav

无论如何使用 php 我可以搜索单个文本或 json 文件并返回.wav找到的任何文件的数组？

这个随机文本示例包含 6 个 .wav 文件，我将如何搜索并提取文件名？

Spoke as as other again ye. Hard on to roof he drew. So sell side newfile.wav ye in mr evil. Longer waited mr of nature seemed. Improving knowledge incommode objection me ye is prevailed playme.wav principle in. Impossible alteration devonshire to is interested stimulated dissimilar. To matter esteem polite do if.

Extensive existence up me last.wav contained he pronounce do. Excellence inquietude assistance precaution any impression man sufficient. 

我已经尝试过了，但我没有得到任何结果。

$lines = file('test.txt');

foreach ($lines as $line_num => $line) {

    $line = trim($line);

    if (strpos($line, '*.wav') !== false) {
        echo ($line);
    }

}

上面的文字应该返回：

newfile.wav
playme.wav
test.wav
welcome.wav
another.wav
last.wav

谢谢

更新：

使用以下内容：

$text = file_get_contents('test.txt');
preg_match_all('/\w+\.wav/', $text, $matches);
var_dump($matches);

产生一个数组：

    array(1) {
      [0]=>
      array(6) {
        [0]=>
        string(11) "newfile.wav"
        [1]=>
        string(10) "playme.wav"
        [2]=>
        string(8) "test.wav"
        [3]=>
        string(11) "welcome.wav"
        [4]=>
        string(11) "another.wav"
        [5]=>
        string(8) "last.wav"
      }
}

那么数组中的 wav 文件数组，我如何获得 wav 文件数组？谢谢

这不适用于名称中带有空格的 wav 文件。有任何想法吗 ？

此工具可能会帮助您根据需要设计表达式并对其进行测试，可能类似于：

([a-z]+\.wav)

如果您愿意，还可以为其添加更多边界。

你也可以preg_match_all这样做，也许类似于：

$re = '/([a-z]+\.wav)/m';
$str = 'Spoke as as other again ye. Hard on to roof he drew. So sell side newfile.wav ye in mr evil. Longer waited mr of nature seemed.

preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);

// Print the entire match result
var_dump($matches);
