使用PHP和LDAP设置accountexpires日期

Question

I'm having trouble setting the 'accountexpires' and wondered if anyone knows a way around it, I believe it's because I have a 18 digit number. I have a form where someone sets a date, I need to set the account to expire then, if I provide the number as a hardcoded string it works, but I cannot convert the finished calculation to a string. Anyone know any way around this? thanks.

<?php
$currentTimeUnix = 1442383989; //this will vary depending on user's input
$secondsBetween1601and1970 = 11644473600;
$timesAdded = $currentTimeUnix + $secondsBetween1601and1970;// comes to 13086857589
$nanoseconds = $timesAdded * 10000000; //comes to 130868575890000000
echo $nanoseconds; //displays 1.3086857589E+017
echo (string)$nanoseconds; //displays 1.3086857589E+017
echo strval($nanoseconds); //displays 1.3086857589E+017
?>

Answer 1

PHP is kind of bad with large numbers but sprintf can help. try:

echo sprintf( '%018.0f', $nanoseconds );
-> 130868575890000000

Alternatively you change the "precision" setting where precision is described:

precision integer

The number of significant digits displayed in floating point numbers.

ini_set("precision",20);
echo $nanoseconds;
-> 130868575890000000
