Not really, but I am running into an issue where once in a blue moon while running this script, my time results in a negative number. here is the part of the script where it is happening:
public function execute()
{
$time1 = microtime();
foreach($this->tables as $table)
{
if($this->buildQuery($table))
{
if($this->submitQuery($table))
{
$time2 = microtime() - $time1;
echo "Sync Successful({$time2}s).. $table <br /> \n";
//log
}
}
else echo "No data to sync in $table";
}
}
As you would suspect.. there should be nothing wrong with subtracting second time from the first and getting a rough estimate of how long the process took.. However.. If I run it enough times, sometimes the results will print out the following:
Sync Successful(0.062936s).. users
Sync Successful(-0.86901s).. profile
Sync Successful(-0.798774s).. groups
Sync Successful(-0.718851s).. phonebook
Sync Successful(-0.711768s).. products
No data to sync in locations
This is very rare, but this is an exact output of my last result. So my questions would be:
How is this possible? resulting in a 'negative' when this should clearly should not happen..
What can I do to avoid this? Is there a better way to go about this? Is microtime() unreliable?
Can someone lend me a 1981 DeLorean DMC-12 capable of 88 mp/h?
