The printf utility (or awk printf function) is not able to determine where digits are in an alphanumeric string. Giving us continually different examples showing that our suggestions don't work when you change your input format is placing those of us trying to help you in a continuing game of whack-a-mole.

Give us a clear definition of the input string formats you want to process, the output strings you want to produce from those input strings, and the parameters that will be supplied to specify output field width, fill characters to be used, where the input strings are coming from (a file, another string, command-line arguments, ...), how to determine where an input string prefix ends and the number begins, etc.

array_pad - Pad array to the specified length with a value

SYNOPSIS
array array_pad (array $array, int $size, mixed $value) DESCRIPTION
array_pad(3) returns a copy of the $array padded to size specified by $size with value $value. If $size is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of $size is less than or equal to the length of the $array then no padding takes place. It is possible to add at most 1048576 elements at a time. PARAMETERS
o $array - Initial array of values to pad. o $size - New size of the array. o $value - Value to pad if $array is less than $size. RETURN VALUES
Returns a copy of the $array padded to size specified by $size with value $value. If $size is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of $size is less than or equal to the length of the $array then no padding takes place. EXAMPLES
Example #1 array_pad(3) example <?php $input = array(12, 10, 9); $result = array_pad($input, 5, 0); // result is array(12, 10, 9, 0, 0) $result = array_pad($input, -7, -1); // result is array(-1, -1, -1, -1, 12, 10, 9) $result = array_pad($input, 2, "noop"); // not padded ?> SEE ALSO
