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.
