This function sorts an array. Elements will be arranged from lowest to highest when this function has completed.
This example would display:
fruits = apple fruits = banana fruits = lemon fruits = orange
The fruits have been sorted in alphabetical order.
The optional second parameter sort_flags may be used to modify the sorting behavior using these values:
Sorting type flags:
SORT_REGULAR - compare items normally
SORT_NUMERIC - compare items numerically
SORT_STRING - compare items as strings
Note: The second parameter was added in PHP 4.
