2 digit numerals starting in 0?

fluShaggy

Basically what the title of the topic is.

I need to create a numeral that is 2 digits [starting with 0] that I can add to.

Since I don't know the actual code... this is what I have tried and it failed...

$i=00;
$i++;

So... I need $i to then progress to "01"... is this possible?

The only way you can have a number start with 0 is that it be a string. What this means is that in your program you'll use the number as an ordinary integer. But when you output it, you output the string with the leading 0. Check out sprintf and number_format . They both take a number (and some other arguments) and return a formatted string.

well... finally I rigged up a counter to combine 2 numerals together.... however... we have a problem completely different.

Is there anyway to make an associative array into a listed array? We have created an array via readdir()

while ($file = readdir($dir))
{ 
  if ($file != "." && $file != "..") 
  { 
    $arra=array($file);

the problem is, this array is associative... but we need to use integers to progress thru it for other reasons... any ideas?

Use array_values() to generate an indexed array from an assoc one.

Just add the filenames to an array

while ($file = readdir($dir))
{ 
  if ($file != "." && $file != "..") 
  { 
    $filearray[] = $file;
