How can differences in PHP versions on different servers affect the results of bitwise shifting operations?

Differences in PHP versions on different servers can affect the results of bitwise shifting operations due to changes in how PHP handles these operations between versions. To ensure consistent results, it is recommended to explicitly cast the operands to integers before performing bitwise shifting operations. 

// Explicitly cast operands to integers before performing bitwise shifting
$number = 10;
$shift = 2;

$result = (int)$number << (int)$shift;

echo $result;
