What are the best practices for accessing specific elements in an array in PHP?

When accessing specific elements in an array in PHP, it is important to check if the key exists in the array before trying to access it to avoid errors. One common way to do this is by using the isset() function to check if the key exists in the array. Additionally, you can also use the array_key_exists() function to check for the existence of a key in an array. 

// Check if key exists before accessing the element
$array = ['key1' => 'value1', 'key2' => 'value2'];

if (isset($array['key1'])) {
    echo $array['key1'];
} else {
    echo 'Key does not exist in the array';
}
