I'll show you how you want, but will recommend using arrays.
<?php
$A0 = '0';
$A1 = '1';
$A2 = '2';
$A3 = '3';
if (isset($A1))
{
$i = 0;
$var_name = "A$i";
while(isset($$var_name))
{
// do something
$i++;
$var_name = "A$i";
}
}
?>
heres what you should be doing.
<?php
$A[] = '0';
$A[] = '1';
$A[] = '2';
$A[] = '3';
if (isset($A))
foreach($A as $pos => $val)
// do something
?>
alot simpler, expandible and easier to read. Im sure its probably faster too...
