腓grep的排序依照档案日期descinding以便与日期

Question

我想与日期降序diplay，并用grep文件进行排序只有

define("SLASH", stristr($_SERVER[SERVER_SOFTWARE], "win") ? "\\" : "/"); 
    function php_grep($path){ 

     $fp = opendir($path); 
     while($f = readdir($fp)){ 
      if(preg_match("#^\.+$#", $f)) continue; // ignore symbolic links 
      $file_full_path = $path.SLASH.$f; 
      if($file_full_path) { 
       $ret .= "$file_full_path\n"; 
      } 
     } 
     return $ret; 
    } 
echo "<pre>"; 
print_r(php_grep("/home"));

你可以做这样的事情：

function php_grep($path){ 
    $ret = array(); 
    $dates = array(); 
    $fp = opendir($path); 
    while($f = readdir($fp)){ 
     if(preg_match("#^\.+$#", $f)) continue; // ignore symbolic links 
     $file_full_path = $path.DIRECTORY_SEPARATOR.$f; 
     if($file_full_path) { 
      $ret[] = $file_full_path; 
     } 
    } 

    array_multisort(array_map('filemtime', $ret), SORT_NUMERIC, SORT_DESC, $ret); 
    return $ret; 
} 
echo "<pre>"; 
php_grep("C:\Workspace");
