在php要获取文件的修改,创建时间我们可以直接使用filemtime() 函数,它可以返回文件内容上次的修改时间。
若成功,则时间以 Unix 时间戳的方式返回。若失败,则返回 false。
filemtime ( string filename )
返回文件上次被修改的时间,出错时返回 FALSE。时间以 Unix 时间戳的方式返回,可用于 date()。
代码如下 | 复制代码 |
$a=filemtime("log.txt"); echo "修改时间:".date("Y-m-d H:i:s",$a); |
filectime ( string filename )
返回文件上次 inode 被修改的时间,如果出错则返回 FALSE。时间以 Unix 时间戳的方式返回。
代码如下 | 复制代码 |
$a=filectime("log.txt"); echo "创建时间:".date("Y-m-d H:i:s",$a); |
fileatime ( string filename )
返回文件上次被访问的时间,如果出错则返回 FALSE。时间以 Unix 时间戳的方式返回。
$a=fileatime("log.txt"); echo "修改时间:".date("Y-m-d H:i:s",$a)."
