如何在 PHP 中保存文件时遍历文件名？

Question

我是 PHP 新手，仍在学习它。这次我想打印一些文本并保存在一个文件中。但我希望自动更改文件名。

例如 file1.txt、file2.txt、file3.txt 等。 到目前为止，这是我的代码：

$read = file("example.txt",FILE_IGNORE_NEW_LINES);
$newFile = "file_1.txt";
$of = fopen($newFile,'w');
foreach($read as $k => $file){
    $line = explode(" ",$file);
    $line2 = array_slice($line,0,3);
    foreach($line2 as $value){
        echo $value." ";
        fwrite($of,$value." ");
    }
    echo "<br>";
    fwrite($of,"\n");

}
fclose($of);

$read = file("example.txt",FILE_IGNORE_NEW_LINES);

$filesToWrite = ["file_1.txt", "file_2.txt","file_3.txt"];
foreach($filesToWrite as $fileToWrite){
    $of = fopen($fileToRead,'w');
    foreach($read as $k => $file){
        $line = explode(" ",$file);
        $line2 = array_slice($line,0,3);
        foreach($line2 as $value){
            echo $value." ";
            fwrite($of,$value." ");
        }
        echo "<br>";
        fwrite($of,"\n");

    }
}
fclose($of);
