Are there any best practices for handling binary files when creating a ZIP file in PHP?

When handling binary files in PHP and creating a ZIP file, it is important to use the appropriate functions to ensure that the binary data is properly encoded and stored in the ZIP file. One common approach is to use base64 encoding for binary data before adding it to the ZIP archive. This ensures that the binary data is preserved and can be correctly decoded when extracting the files from the ZIP archive.

// Create a ZIP archive with binary files using base64 encoding
$zip = new ZipArchive();
$zipFileName = 'archive.zip';
$zip->open($zipFileName, ZipArchive::CREATE);

// Read binary file contents
$binaryData = file_get_contents('binaryfile.jpg');

// Encode binary data using base64
$base64Data = base64_encode($binaryData);

// Add encoded data to ZIP archive
$zip->addFromString('binaryfile.jpg', $base64Data);

$zip->close();

echo 'ZIP file created successfully.';
