title: rand not determined on nginx/php-fpm
body: <p>In my script I use <code>srand(date("Ymd"))</code> for generating determined random numbers in the same sequence all the day. This runs well on my local and apache environment.</p>
  
  <p>On nginx/php-fpm as I have it on the live environment, the <code>rand()</code> is generating another sequence of numbers even though srand was initialized with the same number.</p>
  
  <p>Is there another, more reliable seed function or do i need to write an own generator?</p>
