在最近添加到它的目录中获取最新的15个文件php [duplicate]

Question

This question already has an answer here:

• sort files by date in PHP 5 answers

Suppose there's a directory named "abc"

This directory contains number of files. Out of all these files, I just want latest "X" or latest 15 files in an array(if possible using glob function) in php.

Every help will be greatly appreciable.

Answer 1

// directory for searching files

$dir = "/etc/php5/*";

// getting files with specified four extensions in $files

$files = glob($dir."*.{extension1,extension2,extension3,extension4}", GLOB_BRACE);

// will get filename and filetime in $files

$files = array_combine($files, array_map("filemtime", $files));

// will sort files according to the values, that is "filetime"

arsort($files);

// we don't require time for now, so will get only filenames(which are as keys of array)

$files = array_keys($files);

$starting_index = 0;
$limit = 15;

// will limit the resulted array as per our requirement

$files = array_slice($files, $starting_index,$limit);

// will print the final array

echo "Latest $limit files are as below : ";
print_r($files);

Please improve me, if am wrong
