Find the exact word position in string

Question

Let\'s say I have a string.

$string = red,green,blue,yellow,black;

Now I have a variable which is the position of the word I am searching f

Answer 1

A better way to solve this, would be by converting the string into an array using explode().

$string = ...;
$string_arr = explode(",", $string);
//Then to find the string in 2nd position

echo $string_arr[1]; //This is given by n-1 when n is the position you want.
