The problem with integer => string is only on 32 bit systems
(mongodb >=1.0.0)
MongoDB\BSON\UTCDateTime::__construct — Construct a new UTCDateTime
$milliseconds
)
milliseconds (integer)64-bit integer that represents the number of milliseconds since the Unix epoch (Jan 1, 1970). Negative values represent dates before 1970.
On 32-bit systems, this parameter may be provided as a string.
Example #1 MongoDB\BSON\UTCDateTime::__construct() example
<?php
$utcdatetime = new MongoDB\BSON\UTCDateTime(1416445411987);
var_dump($utcdatetime);
?>
The above example will output something similar to:
object(MongoDB\BSON\UTCDateTime)#1 (1) {
["milliseconds"]=>
int(1416445411987)
}
The problem with integer => string is only on 32 bit systems
For me to get it work with php 5.6 on an iis 7.5, it had to be a string
$utcdatetime = new MongoDB\BSON\UTCDateTime('1416445411987');
