Trying to use:
$encoded = json_encode($facebookIds, JSON_NUMERIC_CHECK);
makes things even worse:
samearray(2) {
[0]=>
float(4.8572380745623E+19)
[1]=>
string(20) "48572380745623087456"
}
array(2) {
[0]=>
float(4.8572380745623E+19)
[1]=>
float(4.8572380745623E+19)
}
It converts "big int" to float, but this is at least visible in var dump.

#$decoded = json_decode($encoded, false, 512, JSON_BIGINT_AS_STRING);
Makes no difference.
Test script output:
array(2) {
[0]=>
float(4.8572380745623E+19)
[1]=>
string(20) "48572380745623087456"
}
array(2) {
[0]=>
float(4.8572380745623E+19)
[1]=>
string(20) "48572380745623087456"
}
Broken

Description:
------------
http://php.net/json_encode
http://php.net/json_decode
json_decode(json_encode(A)) != A
json_encode + json_decode breaks large integers.
Test script:
---------------
<?php
$facebookIds = array(48572380745623087456, '48572380745623087456');
$encoded = json_encode($facebookIds);
$decoded = json_decode($encoded);
var_dump($facebookIds);
var_dump($decoded);
if ($facebookIds != $decoded) {
echo "\nBroken\n";
}
