You could also set $ary_of_FVs as *static* within the function body.

function check_if_FW_TES($value,$key)
{
*static* $ary_of_FVs= array();
// rest of your code
}


*Example*
--------

function counter()
{
static $count = 0;
return ++$count;
}

for ( $i = 0; $i < 10; ++$i )
{
echo counter(), "\n";
}

*Result*:
-------
1
2
3
4
5
6
7
8
9
10
