本文实例讲述了php使用gettimeofday函数返回当前时间并存放在关联数组里的方法。分享给大家供大家参考。具体分析如下：

英文官方描述如下：

Key Description
sec Seconds since midnight before January 1, 1970
usec  Microseconds since the sec value
minuteswest   
Local time zone difference from GMT, in minutes
dsttime  1 iff daylight savings time is in effect,
0 iff not.

<?php
$Now = gettimeofday();
echo "As an associative array:\n";
foreach ($Now as $Key => $Value) {
 echo "$Key => $Value\n";
}
?>

输出结果如下：

sec => 1261918156
usec => 724964
minuteswest => 0
dsttime => 0

希望本文所述对大家的php程序设计有所帮助。
