示例：PHP代碼演示gettimeofday()函數的示例

<?php
//getting the time with all keys
$result = gettimeofday();
echo "gettimeofday()...\n";
print_r($result);
//extracting indivisual values based on the keys
echo "sec:          $result[sec]\n";
echo "usec:         $result[usec]\n";
echo "minuteswest:  $result[minuteswest]\n";
echo "dsttime:      $result[dsttime]\n";
//getting time in float
$result = gettimeofday(true);
echo "result in float: $result\n";
?>
