[SOLVED] Looping Question for all the looping masters

[dubstyleenation]

I need to echo this statement

c=a1+a2+a3;

 

when I try, I only get a1a2a3.

$count = $_POST['count'];

for($i = 1; $i <= $count; $i++) { //$count in this case is 3. $count is never bigger than 6.
echo "a$i"; // Prints a1a2a3. I need it to print a1+a2+a3.
}

 

How can I put the loop results into an array and then implode the array with a plus (+) sign resulting in a1+a2+a3?

<?php
$count = 3;
$ca = array();

for($i = 1; $i <= $count; $i++) { 
    $ca[] = "a$i"; 
}
echo join ('+', $ca);
?>
