/*
The following code produces an unexpected result from the
array_multisort() function.
The indices of the arrays are are modified for the two entries in which
the numeric value reaches the first position of the string index.
Granted, all of the indices are numerical, and therefore may be
assigned to an integer when converted; however, the expected
replacement would be the integer value of the string representation.
(i.e. "150014" would become 150014)
In actuality, the indices "150014" and "120011" are converted to 1 and
0 respectively. Therefore, the associative array is no longer
associative and the indices do not relate to the original arrays, even
though the sort order is correct and the two arrays still relate to
each other.
