How can binary data be effectively handled when using gzcompress/gzuncompress in PHP?

When handling binary data with gzcompress/gzuncompress in PHP, it's important to use the 'gzencode' function instead of 'gzcompress' to ensure that the binary data is properly compressed and decompressed without any loss of information. This is because 'gzcompress' may not handle binary data correctly due to its internal implementation. 

// Correct way to handle binary data with gzcompress/gzuncompress in PHP
$binaryData = file_get_contents('binary_file.bin');

// Compress binary data
$compressedData = gzencode($binaryData);

// Decompress binary data
$decompressedData = gzdecode($compressedData);

// Verify data integrity
if ($binaryData === $decompressedData) {
    echo "Binary data compression and decompression successful!";
} else {
    echo "Error: Binary data compression and decompression failed!";
}
