What are the potential pitfalls when performing binary calculations in PHP?

One potential pitfall when performing binary calculations in PHP is not specifying the base when working with binary numbers. This can lead to unexpected results or errors in calculations. To avoid this issue, always explicitly specify the base as 2 when working with binary numbers in PHP. 

// Incorrect way without specifying base
$binaryNumber = 1010;
$decimalNumber = bindec($binaryNumber); // This will result in an error or unexpected result

// Correct way with specifying base
$binaryNumber = '1010';
$decimalNumber = bindec($binaryNumber); // This will correctly convert binary '1010' to decimal 10
