PHP Fundamentals

Chapter 8: Arrays

8.1 Creating Arrays

// Indexed array
$fruits = ["apple", "banana", "orange"];

// Associative array
$person = [
    "name" => "John",
    "age" => 30,
    "city" => "New York"
];

8.2 Accessing Array Elements

echo $fruits[0];        // apple
echo $person["name"];  // John

8.3 Array Functions

count($array);              // Get array length
array_push($array, $item);  // Add to end
array_pop($array);          // Remove from end
in_array($value, $array);   // Check if value exists
