What can be potential issues when working with indexed arrays in PHP?

  • Accessing non-existent elements can result in errors.
  • Modifying an element does not affect the original array.
  • Indexed arrays can only store a fixed number of elements.
  • Indexed arrays always have a predefined size.
The correct option is 1. Potential issues when working with indexed arrays in PHP include accessing non-existent elements, which can result in errors like "Undefined offset." Modifying an element of an indexed array directly affects the original array. Indexed arrays in PHP can store any number of elements and do not have a predefined size. They can dynamically grow or shrink as elements are added or removed. Learn more: https://www.php.net/manual/en/language.types.array.php
