Various times for php to read files_PHP tutorial

To get the modification and creation time of a file in PHP, we can directly use the filemtime() function, which can return the last modification time of the file content.

If successful, the time is returned as a Unix timestamp. On failure, returns false.

filemtime ( string filename )

Returns the time when the file was last modified, and returns FALSE if an error occurs. The time is returned as a Unix timestamp, usable with date().

The code is as follows

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);

Copy code

$a=filemtime("log.txt");

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);

echo "Modification time:".date("Y-m-d H:i:s",$a);

代码如下	复制代码
$a=fileatime("log.txt");    echo "修改时间：".date("Y-m-d H:i:s",$a)."

filectime ( string filename ) Returns the time when the file's inode was last modified, or FALSE if an error occurs. The time is returned as a Unix timestamp.

The code is as follows

Copy code

$a=filectime("log.txt");

echo "Creation time:".date("Y-m-d H:i:s",$a); fileatime ( string filename ) Returns the time the file was last accessed, or FALSE if an error occurred. The time is returned as a Unix timestamp.
