The above code can be slow, because the array size is fetched on every iteration. Since the size never changes, the loop can be easily optimized by using an intermediate variable to store the size instead of repeatedly calling count():

Use a foreach loop, it loops through all the key=>value pairs:
foreach($array as 
value){
print "$key holds $value\n";
}
Or to answer your question completely:
foreach($array as $value){
print $value."\n";
}

You can achieve this in this way as well.
<?php
$products = array('Volvo', 'BMW', 'Toyota', 'Kijang');
for(
i<count($products);$i++){
echo implode(", ",$products);
echo "<br>";
array_push($products, array_shift($products));

Volvo, BMW, Toyota, Kijang
BMW, Toyota, Kijang, Volvo
Toyota, Kijang, Volvo, BMW
Kijang, Volvo, BMW, Toyota
You can run the code in here.Hope this will help you.
