How to find PHP execution time?
In PHP version 7+, the getrusage function can be used. Below is a sample code demonstration −
Example
//beginning of the script
$exec_start = getrusage();
//other code functionalities
//end of the script
function rutime($ru, $rus, $index) {
return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))
- ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000));
}
$ru = getrusage();
echo "The process used " . rutime($ru, $exec_start, "utime") .
" ms for the computations
";
echo "Spent " . rutime($ru, $exec_start, "stime") .
" ms during system calls
";Note − There is no need to calculate the time difference if a php instance is spawned for every test.
Output
This will produce the following output −
The process used 1.563896 ms for the computations Spent 0.345628 ms during system calls
