PHP Array Tutorial

Arrays

2. Accessing a particular element in an array by referring to the name of the array and the index number.

4. If you specify numbers or true/false values inside the array then the variable type will be Number or Boolean, instead of String.

An array can be defined in three ways:

            $people[0] = "Oliva";
            $people[1] = "Nicole";
           $people[2] = "Natasha";
           echo $people[1];
        ?>

        <?php
              $people = array('Oliva', 'Nicole', 'Natasha');
