检查PHP函数的服务器运行时和Internet流量

Question

I want to consult you.

I want to build a 'testing code' of PHP functions, that will chek which function is better.

the 'testing code' need to check:

• how much time (at milliseconds) its take to the server to run the function.
• how much internet traffic the function will use.

someone have any idea how could i check this things?

Answer 1

What I understand is that you want to do a benchmark.

To know how much time a function needs, you can do it with this function :

function microtime_float()
{
    list($usec, $sec) = explode(" ", microtime());
    return ((float)$usec + (float)$sec);
}
$timeStart = microtime_float();
// your function
$timeEnd = microtime_float();
echo $timeEnd - $timeStart , ' seconds.';

The advantage of this function is that you will obtain a result in miliseconds, so it will be way more precise than a timestamp.

I would advise you to execute the function in a loop to obtain an average time, and to be more accurate.

For the network traffic, I think the simplest is to count the number of bytes you send, and the number of byte you receive. In case of a curl for example, it should be pretty straigh forward.

I hope this helps.
