quick php/general programming question

Right down to it,
incramenting a number is no hassel right, but i want to incrament a formatted number.

say my number is "000001" it needs to be displayed as is, because it becomes part of an sql statement.

so for each loop i want 1 to be added to this number, ie it will be "000002" "000003" and so on.

$num = intval($docid)+1;
if ($num>9)
   {
   $id = "0000" . $num ;
   #$id = printf("%5s", $num);
   }
else
$id =  "00000" . $num;

should this work?
its been anoying me now for a few hours and i need to get over this to move to the next step of the script.

thanks in advance for your help,
Flame

Well this works, but it's not very elegant or scaleable.
You should be able to translate pretty much directly
[php]
#!/usr/bin/perl -w

my $i = 0;
my $padding = "0000";

for ($i = 0; $i <= 10000; $i++)
{
if ($i > 10000)
{
$padding = "";
}
elsif ($i > 1000)
{
$padding = "0";
}
elsif ($i > 100)
{
$padding = "00";
}
elsif ($i > 10)
{
$padding = "000";
}
else
{
$padding = "0000";
}
print $padding . $i . "\n";
}

[/php]

Kev

what about

sprintf( "%06d", $i );

for more about sprintf check out the php manual
