[SOLVED] leading zero if less then 10?

[onedumbcoder]

I am trying to create a  number with this formate 0101

 

and incremented like this 0201 0301  0402 0502 0602.....

 

so i do i create something what will maintain that.

 

when i did this

 

$a = 01;

 

$b = 01;

 

$a++;

$b++

 

$tracker = $a . $b

 

i get 22

Make 0 a string and not a number.

 

so, $zero = "0";

$a = 1;

$b = 1;

$a++;

$b++;

$tracker = $zero . $a . $zero . $b;

 

You would need an if statement to check if $a and $b are less than 0, and display $zero if they are.

<pre>
<?php
$a = 1;
$b = 22;
printf('%02d%02d', $a, $b);
?>
</pre>

$tracker = printf('%02d%02d', $a, $b);

Use sprintf to return a string.
