Question

I’m using PDO, is there any way, to measure how long does it take to complete the query?

Answer 1

You could use microtime(true) to get the seconds needed to execute:

$start = microtime(true);
//Your code
echo 'Time needed: ' . (microtime(true) - $start) . '.';

To get a more accurate time you should do that test more times (10000 here):

$start = microtime(true);
for ($i = 0; $i < 10000; ++$i) {
    //Your code
}
echo 'Time needed: ' . (microtime(true) - $start) . '.';

@Baz1nga, that code doesn’t work, since microtime_float() isn’t a function (Sorry, I can’t comment, need more reputation :()
