I have a variable, lets say

$var = "name1 field2_name name3 name4";

i need them to be in an array separately like this

$arr = array ('name1', 'field2_name', 'name3', 'name4');

so i can echo words in separate like this

echo $arr[0]; //echoes name1

</div>

use the php explode function

$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
