Are there specific PHP functions or methods that can streamline the process of adding leading zeros to numerical values for database entry?

When adding numerical values to a database, we may need to ensure that they have a consistent format, such as having leading zeros. One way to achieve this is by using PHP functions like `str_pad()` or `sprintf()` to add the necessary zeros to the numerical value before inserting it into the database. 

// Example code to add leading zeros to a numerical value before inserting into a database
$num = 123;
$length = 5; // Desired length of the final value
$padded_num = str_pad($num, $length, '0', STR_PAD_LEFT);

// Now $padded_num contains '00123', which can be safely inserted into the database
// Insert $padded_num into the database using your preferred method
