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。
