Note that keys are preserved. <function>array_unique</function> sorts
the values treated as string at first, then will keep the first key

<parameter>array</parameter> will be kept.
Note that keys are preserved. If multiple elements compare equal under
the given <parameter>sort_flags</parameter>, then the key and value of
the first equal element will be retained.
