uasort --
Sort an array with a user-defined comparison function and
maintain index association
Description
void
uasort ( array array, function cmp_function)
This function sorts an array such that array indices maintain
their correlation with the array elements they are associated
with. This is used mainly when sorting associative arrays where
the actual element order is significant. The comparison function
is user-defined.
Note:
Please see usort() and
uksort() for examples of user-defined
comparison functions.
Note: Instead of a function name, an
array containing an object reference and a method name can also be
supplied.
