Keep Zero In Front of Digit?

[chaseman]

This for loop:

 

for ($m = 01; $m <= 12; $m++)

 

Will output:

1

2

3

4

etc.

 

And NOT:

01

02

03

04

 

 

My question is: how can I make the number be 2 digits and have it output together with the ZERO?

 

And when it's reaching the number 10 it should continue outputting:

 

10

11

12

 

And not

 

010

011

etc.

Not pretty, but it works.

 

for ($m = 1; $m <= 12; $m++) {

$use = $m;

if($m < 10) $use = '0'.$m;

 

echo $use;

}

Thanks for the tip, this is how I solved it in my specific example:

 

	if ($d < 10) {
	$zero_d = '0'. $d;
	} else {
	$zero_d = $d;
	}

 

The else statement was important in my case otherwise it would output:

 

09

09

09

09

 

Instead of

 

09

10

11

12

for($i = 1; $i <= 12; ++$i)
    printf('%02d', $i);

You can also use the str_pad as a simpler version of printf.

echo str_pad($m, 2, '0', STR_PAD_LEFT);

[chaseman]

for($i = 1; $i <= 12; ++$i)
    printf('%02d', $i);

 

 

Pretty elegant solution, thanks a lot.
