How Do I Access Array Elements, Object Properties, and Nested Structures in PHP?

Accessing Array Elements:

To access an element in an array, use square brackets ([]).

echo $array[0]; // Accesses the first element of the array

Accessing Object Properties:

To access a property of an object, use the arrow operator (->).

echo $object->property; // Accesses the "property" property of the object

Accessing Elements in Nested Arrays and Objects:

To access elements in nested arrays or objects, simply chain the brackets or arrow operators together.

$nestedArray = [
    'data' => [
        ['property' => 'value1'],
        ['property' => 'value2'],
    ]
];

echo $nestedArray['data'][0]['property']; // "value1"

$nestedObject = [
    'data' => (object) [
        'property' => 'value1'
    ]
];

echo $nestedObject->data->property; // "value1"
