What are common pitfalls when trying to access specific elements in an array in PHP?

Common pitfalls when trying to access specific elements in an array in PHP include not checking if the key exists before accessing it, using incorrect syntax for array access, and not handling multidimensional arrays properly. To avoid these pitfalls, always use isset() or array_key_exists() to check if the key exists before accessing it, use square brackets [] for array access, and correctly navigate through multidimensional arrays.

// Example of accessing specific elements in an array in PHP

// Define an array
$array = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => array(
        'subkey1' => 'subvalue1',
        'subkey2' => 'subvalue2'
    )
);

// Check if key exists before accessing it
if (isset($array['key1'])) {
    echo $array['key1']; // Output: value1
}

// Accessing elements in a multidimensional array
echo $array['key3']['subkey1']; // Output: subvalue1
