How can the issue of accessing array offsets and null values be resolved in PHP code, as discussed in the thread?
Issue: The problem of accessing array offsets and null values can be resolved in PHP by using the null coalescing operator (??) to provide a default value if the offset or value is null. Solution:
// Example array with potential null values
$array = ['a' => 'apple', 'b' => null, 'c' => 'cherry'];
// Accessing array offsets with null coalescing operator
$valueA = $array['a'] ?? 'default value';
$valueB = $array['b'] ?? 'default value';
$valueC = $array['c'] ?? 'default value';
echo $valueA . "\n"; // Output: apple
echo $valueB . "\n"; // Output: default value
echo $valueC . "\n"; // Output: cherry
