Are there any version-specific considerations when trying to access a value directly from a returned array in PHP?

When trying to access a value directly from a returned array in PHP, it's important to check the PHP version you are using. In PHP 7.1 and above, you can use the null coalescing operator (??) to safely access array values without triggering notices if the key does not exist. This operator returns the value on the left if it exists and is not null, otherwise it returns the value on the right. 

// Example of safely accessing a value from a returned array in PHP 7.1 and above
$array = ['key' => 'value'];

// Using null coalescing operator to access the value safely
$value = $array['key'] ?? 'default value';
echo $value;
