What can be potential issues when sorting arrays in PHP?
- Loss of key-value associations in associative arrays.
- Unexpected sorting results due to incorrect data types.
- Performance issues with large arrays.
- All of the above.
The correct option is 4. When sorting arrays in PHP, potential issues may arise. Sorting an associative array using functions like sort() or rsort() can lead to the loss of key-value associations, as these functions primarily work on indexed arrays. Additionally, sorting arrays with incorrect data types can produce unexpected results. For example, sorting an array with a mix of numeric and string values may not give the desired outcome. Another potential issue is performance, especially when sorting large arrays, as sorting algorithms have time complexity considerations. It is important to consider these issues and select the appropriate sorting function based on the specific requirements and characteristics of the array.
