What are best practices for handling errors related to string offsets in PHP arrays?

When working with PHP arrays, it's important to handle errors related to string offsets to avoid potential issues such as notices or warnings. One common approach is to check if the offset exists in the array before accessing it to prevent errors. This can be done using functions like isset() or array_key_exists() to ensure the offset is valid before attempting to retrieve its value. 

// Example of handling errors related to string offsets in PHP arrays
$array = ['foo' => 'bar', 'baz' => 'qux'];

// Check if the offset exists before accessing it
if (isset($array['foo'])) {
    $value = $array['foo'];
    echo $value;
} else {
    echo 'Offset does not exist in the array';
}
