Php Development-array sorting

One of the advantages of array sorting array developed by php over other variable types is that it can be sorted. PHP includes multiple functions for sorting arrays. their syntax is simple:

$ Names = array ("Moe", "Larry", "Curly"); sort ($ names );

These sorting functions perform three types of sorting. First, you can use the sort () function to sort the array by value and discard the original key. It is important to understand that the keys of the array will be reset after the sorting process. Therefore, if the key-value relationship is very important, this function should not be used.
Second, you can use the asort () function to sort the array by value and maintain the key. Finally, you can use the ksort () function to sort the array. If you change these functions to rsort (), arsort (), and krsort (), you can sort the arrays in reverse order.
