PHP – Check If Array Element is Null

Hi guys, in this short tutorial, we will see how can we check in PHP  If Array Element is Null or not. So let’s get started.

To check if an element in an array is null in PHP, you can use the isset() function. This function returns true if the variable is set and is not null, and false if the variable is not set or is null.

Here is an example of how you can use isset() to check if an element in an array is null:

$array = ['foo', 'bar', null, 'baz'];

if (isset($array[2])) {
// The element at index 2 is not null
} else {
// The element at index 2 is null
}

You can also use the is_null() function to check if a value is null. This function returns true if the value is null, and false if it is not.

$array = ['foo', 'bar', null, 'baz'];

if (is_null($array[2])) {
// The element at index 2 is null
} else {
// The element at index 2 is not null
}

Note that isset() will return false if the element is not set or is null, while is_null() will return true only if the element is null.
