Re: [PHP] Time consumed in microseconds
Darn missed it. Looking into the docs I am using code
somthing like this:
$start = microtime();
$result = mysql_query ( $query, $mysql );
$end = microtime();
$diff = microtime_diff ($start, $end);
function microtimdiff() is given by:
function microtime_diff($a, $b)
{
list($a_dec, $a_sec) = explode( , $a);
list($b_dec, $b_sec) = explode( , $b);
return ((float)$b_sec - (float)$a_sec +
(float)$b_dec - (float)$a_dec);
}
The result from one operation is like:
$start = 0.26562800 1093931165
$end = 0.26813400 1093931165
$diff = 0.002506
So to get the difference in ms I have to multilply
$diff by 1000.
Am I correct?

How can I get it in PHP. I want the exact figure
in
ms? I used microtime() and the samples given in
php.net but none of them correctly returns the
difference only in ms?
Read the manual page again. Use the example to get
the microtime as a
float at the start and then after your job. Subtract
to get the
difference. If you're using PHP5, just use
microtime(TRUE); to get the
float value.
