PHP filectime() Function Usage and Example

PHP Filesystem Reference Manual

The filectime() function returns the last modified time of the specified file. This function can check daily modifications of the file and inode modifications. Inode modifications can refer to permission modifications, owner modifications, group modifications, or other metadata modifications. If successful, the function will return the last modified time of the file as a Unix timestamp. If it fails, it will return false.

Syntax

int　filectime　(　string　$filename　)

You can cache the result of this function and use clearstatcache() to clear the cache. We can use the filemtime() function to return the last modified time of the file content.

Online Example

<?php
　　　echo　filectime("/PhpProject/sample.txt");
　　　echo　"\n";
　　　echo　"Last Modified:　".date("Y-m-d　H:i:s.",filectime("/PhpProject/sample.txt");
?>
