Bug description: array_multisort() changes array keys unexpectedly given numeric
strings as keys
<script language="php">
/*
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
and 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.
