Do PHP developers need to manually decompress and compress data before using the bzread and bzwrite functions for bzip2 files?

When using the bzread and bzwrite functions in PHP for bzip2 files, developers do not need to manually decompress or compress the data. These functions handle the compression and decompression internally, allowing developers to read and write data to bzip2 files directly.

// Open a bzip2 file for reading
$handle = bzopen('example.bz2', 'r');

// Read data from the bzip2 file
$data = bzread($handle, 4096);

// Close the bzip2 file
bzclose($handle);
