if & else function

newsiness · 08-30-2007, 05:50 AM

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

PHP Code:

  if(strlen($p)==1){

  $p = "000".$p;

} elseif(strlen($p)==2) {

????: NamePros.com http://www.namepros.com/programming/368146-resolved-if-and-else-function.html
  $p = "00".$p;

????: NamePros.com http://www.namepros.com/showthread.php?t=368146
} elseif(strlen($p)==3) {

  $p = "0"+$p;

}

I personally would build a function to handle it:

PHP Code:

  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;
}

Or better yet have a look at the str_pad function
