Tutorial on zero-padding before decimal to binary, octal, and hexadecimal-less digits

Decimal to binary, octal, and hexadecimal digits are not followed by zeros .? Php Tutorial *** convert decimal to binary, octal, and hexadecimal with less than a single digit to zero *** @ paramarray $ datalist input data array (100,123,130) * @ paramint $ bin conversion in hexadecimal format

/**
