How can PHP Bit-Operators be used to extract specific values from binary data for version encoding?

When working with binary data for version encoding, PHP Bit-Operators can be used to extract specific values from the binary data. This is useful when you need to extract certain bits representing a version number from a binary string. By using bitwise operators such as bitwise AND (&) and bitwise shift (<<), you can extract the desired bits and convert them into a version number. 

// Binary data representing version encoding
$binaryData = &quot;\x05\xA2\x0F&quot;;

// Extracting version number using bitwise operators
$version = ord($binaryData[0]) &amp; 0b00000111; // Extracting 3 bits representing version number
$majorVersion = ord($binaryData[1]);
$minorVersion = ord($binaryData[2]);

echo &quot;Version: $version.$majorVersion.$minorVersion&quot;; // Output: Version: 5.162.15
