Easy way to find if a number is prime or not.
<?php
$ammt = 15;
for ( $counter = 1; $counter <= $ammt; $counter += 1) {
$number = $ammt/$counter;
if ($counter != 1 && $counter != $ammt){
if (is_int($number)){
$composite = 1;
}
}
}
if ($composite){
print "$ammt is a composite number.";
}else{
print "$ammt is a prime number.";
}
?>
