Modifying Array Elements
An item in an array can be changed by specifying its position and providing a new value, like this:
<?php
$myArray = array("red", "blue", "yellow");
echo $myArray[1];
// outputs "blue"
$myArray[1] = "green";
echo $myArray[1];
// outputs "green"
?>
- First we create a new array
$myArraywith a list of colors. - Then we output the item at position 1. Since items are numbered starting from 0,
"blue"is at position 1 - Next we change the item at position 1 to
"green". - Now when we output the item at position 1, we get
"green".
