Are there any specific PHP functions or libraries that can simplify the process of converting decimal numbers to binary numbers?

Converting decimal numbers to binary numbers in PHP can be simplified by using the built-in function `decbin()`. This function takes a decimal number as input and returns its binary representation. By using `decbin()`, you can easily convert decimal numbers to binary numbers without having to implement the conversion logic yourself.

// Convert decimal number to binary using decbin()
$decimalNumber = 10;
$binaryNumber = decbin($decimalNumber);

echo "Binary representation of $decimalNumber is: $binaryNumber";
