@NogDogSep 21.2007 — #If you are using PHP 4.2.0 or later, there is no reason. If you are using an older version (hopefully not!), then its purpose is to "seed" the random number generator with a pseudo-random number (the current time in microseconds) so that each call to the script will result in a different sequence of random numbers from the rand() function. Again, this is a redundant waste of processing time in any reasonably recent version of PHP.
srand()
What would be the purpose of seeding srand with microseconds like in php manuals main example found here:
[url]http://us.php.net/manual/en/function.srand.php
[code=php]<?php
// seed with microseconds
function make_seed()
{
list($usec, $sec) = explode(‘ ‘, microtime());
return (float) $sec + ((float) $usec * 100000);
}
srand(make_seed());
$randval = rand();
?>
