For statement

Traversing Arrays Using foreach in PHP

$users = array("Mani", "Nani", "Item", "Raja");
print "The users are:\n";
foreach ($users as $key => $value) {
print "#$key = $value\n";
}

Output:
The players are:
#0 = Mani
#1 = Nani
#2 = Item
#3 = Raja

Using the for Loop in PHP

<?php
echo("Prime Numbers between 1 and 30<p>");
//For loop from 1 to 30
for($var=1;$var<30;$var++)
{
   $ctr=0;
   for($k=2;$k<=$var/2;$k++)
   {
      $d=$var%$k;
      if ($d == 0)
      {
         $ctr=1;
         break;
      }
   }
   if($ctr==0)
   {
      echo($var);
      echo("<br>");
   }
}
?>
