What can be potential issues when working with associative arrays in PHP?
- Accessing non-existent elements can result in errors.
- Modifying an element does not affect the original array.
- Associative arrays can only store a fixed number of elements.
- Associative arrays always have a predefined size.
The correct option is 1. When working with associative arrays in PHP, accessing non-existent elements can result in errors, such as "Undefined index." It is crucial to ensure that the desired keys exist in the associative array before attempting to access them. Modifying an element in an associative array directly affects the original array, as they are passed by reference. Associative arrays in PHP can dynamically grow or shrink based on the number of key-value pairs, and they do not have a predefined size. They can store any number of elements, allowing for flexibility in data representation. Learn more: https://www.php.net/manual/en/language.types.array.php#language.types.array.syntax
