PHP：有序目录列表

Question

How to list files in a directory in "last modified date" order? (PHP5 on Linux)

Answer 1

function newest($a, $b) 
{ 
    return filemtime($a) - filemtime($b); 
} 

$dir = glob('files/*'); // put all files in an array 
uasort($dir, "newest"); // sort the array by calling newest() 

foreach($dir as $file) 
{ 
    echo basename($file).'<br />'; 
} 

Credit goes here.
