Displaying elements of an array by looping

• Creating and displaying Array

 $a= array("Three", "two", "Four", "five","ten");


while (list ($key, $val) = each ($a)) {
echo "$key -> $val 
<br>";
}

Using sizeof function to display all elements using for loop

$a= array("Three", "two", "Four", "five","ten"); 
$max=sizeof($a);
for($i=0; $i<$max; $i++) { 
echo "$a[$i] ,"; 
}

Displaying one element

$a= array("Three", "two", "Four", "five","ten"); 
echo $a[2]; // Output is Four

$mark=array("John"=>85,"Raju"=>75,"Alex"=>48,"Ronald"=>52); 

echo $mark[Alex]; // Output is 48

Using print_r

$a= array("Three", "two", "Four", "five","ten"); 
print_r($a);

Array ( [0] => Three [1] => two [2] => Four [3] => five [4] => ten ) 

$ar=array("FName"=>"John","Address"=>"Streen No 11 ","City"=>"Rain Town","Country"=>"USA");

print_r($ar);

Array ( [FName] => John [Address] => Streen No 11 [City] => Rain Town [Country] => USA )
