在PHP中,可以使用gzcompress()gzuncompress()函數(shù)來實現(xiàn)二進制數(shù)據(jù)的壓縮和解壓縮。

壓縮數(shù)據(jù):

$data = "Hello, World!";
$compressedData = gzcompress($data);

解壓縮數(shù)據(jù):

$uncompressedData = gzuncompress($compressedData);
echo $uncompressedData; // Output: Hello, World!

另外,也可以使用base64_encode()base64_decode()函數(shù)來對二進制數(shù)據(jù)進行編碼和解碼,從而實現(xiàn)數(shù)據(jù)的壓縮和解壓縮:

$data = "Hello, World!";
$compressedData = base64_encode(gzcompress($data));
$uncompressedData = gzuncompress(base64_decode($compressedData));
echo $uncompressedData; // Output: Hello, World!
