How can undefined offset errors be resolved in PHP arrays?

Undefined offset errors in PHP arrays occur when trying to access an index that does not exist in the array. To resolve this issue, you can check if the offset exists before trying to access it using functions like isset() or array_key_exists(). This ensures that you only access valid array indices.

// Check if offset exists before accessing it
if(isset($array[$index])) {
    // Access the array element at the specified index
    $value = $array[$index];
    // Use the value as needed
} else {
    // Handle the case when the offset is undefined
    echo "Offset does not exist in the array";
}
