<function>array_intersect_uassoc</function> returns an array
|
|
containing all the values of <parameter>array1</parameter>
|
|
that are present in all the arguments. Note that the keys are used in
|
|
the comparison unlike in <function>array_intersect</function>.

</para>

|
<para>
|
|
The index comparison is done by a user supplied callback function.
|
|
It must return an integer less than, equal to, or greater than zero
|
|
if the first argument is considered to be respectively less than,
|
|
equal to, or greater than the second.
