In what ways can PHP developers optimize file naming conventions to ensure cross-platform compatibility for zip archives?

To ensure cross-platform compatibility for zip archives, PHP developers can optimize file naming conventions by avoiding special characters, spaces, and long file names. Instead, they should use alphanumeric characters and underscores to ensure that the files can be extracted correctly on different operating systems.

// Example of optimizing file naming conventions for cross-platform compatibility
$filename = "my_file.zip";
$zip = new ZipArchive;
if ($zip->open($filename) === TRUE) {
    $zip->extractTo("/path/to/extract/");
    $zip->close();
    echo 'File extracted successfully.';
} else {
    echo 'Failed to extract file.';
}
