[Resolved] If & else function

[newsiness]

if & else function

if(a.length == 1 ){
a = "000"+a;
}else if(a.length == 2){
a = "00"+a;
}else if(a.length == 3){
a = "0"+a;
}

How to rewrite the similiar function above for $p in php?
Can I replace "a" with "$p" ? It doesn't work at all. Any idea? Thanks

if(strlen($p)==1){
  $p = "000".$p;
} elseif(strlen($p)==2) {
  $p = "00".$p;
} elseif(strlen($p)==3) {
  $p = "0"+$p;
}

I personally would build a function to handle it:

function leading_zeros($num,$zeros){
	$len = strlen($num);
  	for($i=$len;$i<$zeros;$i++){
   		$num = "0".$num;
  	}
  	return $num;
}
 
$p = leading_zeros($p,4);

function leading_zeros($num,$zeros){
$len = strlen($num);
for($i=$len;$i<$zeros;$i++){
$num =. "0";
}
return $num;
}

Thanks, it works!!! Rep added...

Or better yet have a look at the str_pad function
