adding a 0 in front

[drisate]

Hey guys i have a number

 

ex: 4

 

And i need it to be formatted into a minimum of 2 characters.

 

Ex: 04

 

1. count the numbers of character of the string

2. If 1 number found add 0 in front

 

I was wandering if there was a faster way to do it with an already made php function?

[premiso]

$string = "1";
if (strlen($string) < 2) {
    $string = "0" . $string;
}

 

As far as a faster way or function to do this, I am not sure. You could easily make the above into a function, however.

come on premiso...i thought you were better then that

 

<?php
  $num = '1';
  printf('%02d',$num);
?>

 

update: if you need to store it in a variable, just use sprint() instead

Not for the past couple weeks. Crazy ass thyroid is acting up and is messing with my brain. It is freaking ridiculous.

 

That and I never really used printf or sprint, good to know

[rhodesa]

p.s - that was supposed to be sprintf()

 

printf() and sprintf() are SO powerful. it cleaned my code up so much once I started using them

 

...and if printf() scares you, you can always use str_pad() in this case
