Reading array values

Reading array values

In PHP, you can read values from an array using the array key. The syntax for accessing an array value is as follows: $array_name[‘key’]. Here, $array_name refers to the name of the array, and ‘key’ is the index of the value you want to access.

For example, consider the following array:

$colors = array(‘red’, ‘green’, ‘blue’);

To access the value at index 1 (which is ‘green’), you would use the following code:

echo $colors[1];

This would output “green” to the screen.

You can also use a loop to iterate over all the elements in an array and read their values one by one. For instance, you can use a foreach loop as follows:

foreach ($colors as $color) { echo $color . ‘<br>’; }

This would output each color in the array on a separate line.
