    No matter which loop you use, you just need proper format to get key/value 
    <?php
$CHAMP = array("ESP"=>"BARCELONA", "GER"=>"BAYERN", "POR"=>"BENFICA","ENG"=>"CHELSIA");
$TEAM = array("ESP"=>"ATLETICO", "GER"=>"LEVERKUSEN", "POR"=>"PORTO","ENG"=>"ARSENAL","ESP"=>"REAL MADRID");
$keys = array_keys($TEAM);
$TEST = array("ESP"=>"BARCELONA", "GER"=>"BAYERN","ENG"=>"ARSENAL","ESP"=>"REAL MADRID");

while (list($key, $val) = each($CHAMP)) {
	print "While loop: $key is $val\n";
}
for ($i = 0; $i < count($TEAM); ++$i) {
	print "For loop: ".$keys[$i]." is ".$TEAM[$keys[$i]]."\n";
}
foreach($TEST as $key => $val) {
	print "Foreach loop: $key is $val\n";
}

?>

    Hello Basant,

    I just go through your code and i found that you are retrieving keys using array_key function and using for loop then. you need to use the foreach loop to retrieve the both keys as well as values. Kindly check the code below.

    <?php
$arr = array('name'=>'Deepak','designation'=>'Software Engineer');
foreach($arr as $key=>$val){
echo $key. "\t" . $val;
}
?>

    Thank You
