Number Formatting

I realize there's a function called number_format() but from how I interpret the documentation, it doesn't do what I want it to.

I'm looking for a way to display more digits. For example, instead of 6, display 00006 ...

number_format() seems to deal with decimal and precision (and slight currency)

PHP Code:


		
			
/************************************************

If all you need to do is pad the string to 5 total char's

************************************************/

$_input = '6';

$_x = 5 - strlen( $_input );

$_data = str_repeat( "0", $_x );

$_out = $_data . $_input;

echo( $_out );

You could also use str_pad():

PHP Code:


		
			
<?php



$num = 6;

$newNum = str_pad($num, 5, 0, STR_PAD_LEFT);



echo $newNum;



?>

The above code would return 00006 to the browser

alternative??

Alternatively, you could write:

PHP Code:


		
			
 $in = 6;

$out = sprintf( "%06d", $in );

echo $out;

This would return '000006' and also works with 2 or more digits (e.g. '212' -> '000212') without changing your code or make calculations on the number of digits.

You could also use:

PHP Code:


		
			
 $in = 6;

printf( "%06d", $in );

This produces the output '000006' straight away.
