How does PHP handle numeric values with leading zeros compared to other programming languages like C?

In PHP, numeric values with leading zeros are treated as octal numbers. This means that if you have a numeric value with leading zeros, PHP will interpret it as an octal number and convert it accordingly. To prevent this behavior and treat the number as a regular decimal number, you can use the intval() function to explicitly convert the value to an integer. 

$number = '0123';
$decimalNumber = intval($number);
echo $decimalNumber; // Output: 123
