Well, that big number is not converted as a string and printed this way, or
I am missing something.
Here is an example:
<?php
$var = 1000000000000;
//Here I have also tried inserting $var = (string) $var;
echo "$var";
?>
This prints:
1E+012
and... not 1000000000000 as it should.
I have first tried just echo $var, but I thought that maybe if I put it
between quotes, it will be printed right, but...
Thank you.
Teddy

Good point :)
When you're outputting it, PHP will convert it back to a string, using
the normal integer representation (which is stored aswell). So that
should be fine ;)
