What is the purpose of using fwrite to create files with decremented file names in PHP?

When creating multiple files in PHP with decremented file names, using fwrite allows you to easily write content to each file sequentially. This can be useful when you need to generate a series of files with names like "file1.txt", "file2.txt", "file3.txt", etc. By using fwrite in conjunction with a loop that decrements the file name, you can efficiently create these files without having to manually write to each one individually.

// Specify the base file name and the number of files to create
$baseFileName = "file";
$numFiles = 5;

// Loop through and create files with decremented file names
for ($i = $numFiles; $i > 0; $i--) {
    $fileName = $baseFileName . $i . ".txt";
    $content = "This is file number " . $i;
    
    $file = fopen($fileName, "w");
    fwrite($file, $content);
    fclose($file);
}
