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.
The code is as follows Copy code
$a=fileatime("log.txt");
echo "Modification time:".date("Y-m-d H:i:s",$a)."
