PHP获得毫秒的时间microtime()用法
在php中如果我们要获取毫秒就必须通过microtime()再进行转换,下面我来给各位朋友举几个实例,希望对大家会有所帮助。
问题不怕弱智…啥都记
代码如下 | 复制代码 |
function getmicrotime() |
其实就是处理了一下microtime()这个函数。
microtime()这个函数的返回值是这种形式:
0.06261400 1303715872
空格后面为当前的时间戳,空格前面是当前的精确时间
例,计算页面执行时间函数
代码如下 | 复制代码 |
/** $time_start = microtime_float(); // Sleep for a while $time_end = microtime_float(); echo "Did nothing in $time secondsn"; |
