while loop for var name

[brem13]

hey, i'm trying to make a while loop that will make a var name go up by number, ie($pic1, $pic2, $pic3, etc) if the value isnt blank, however its not doing it the way i want,

 

$i = 0;
$count = 0;
while($i<=5)
{
$i++;
if($$pic.$i=="")
$count++;
}//end while

Why do you want to do that? It seems more appropriate that you would use an array to store a list of something.

 

For what it's worth, you would use ${'pic'.$i} to access the numbered variables: see variable variables in the manual.

Try

<?php
$count = 0;
for ($i=0;$i<6;++$i) {
   if (${'pic'.$i}  != '') {
       $count++;
   }
}
echo $count;
?>
