PHP readdir和排序

Question

我正在做一个小画廊.我想从目录中读取文件名,并在删除一些前导数字和文件扩展名后打印下面的文件名.

我有两个版本的代码.

版本1不排序

$current_dir = "$DOCUMENT_ROOT"."/weddings2/";   
$dir = opendir($current_dir);        // Open the sucker

while ($file = readdir($dir))            // while loop
  {
$parts = explode(".", $file);                    // pull apart the name and dissect by period
if (is_array($parts) && count($parts) > 1) {    // does the dissected array have more than one part
    $extension = end($parts);        // set to we can see last file extension
    $bfile= substr($file, 2); //strips the first two characters
    $cfile= preg_replace(('/\d/'),' ',$bfile);//remove numbers
    $cfile= preg_replace(('/_/'),' ',$cfile); 
    $cfile= preg_replace(('/.jpg/'),' ',$cfile);
            if ($extension == "jpg" OR $extension == "JPG")    // is extension ext or EXT ?
    echo "<td><img src=\"weddings2/$file\"><br />$cfile</td>\n";

    }
}
closedir($dir);        // Close the directory after we are done

版本2排序,但我无法操纵文件名

$current_dir = "$DOCUMENT_ROOT"."/weddings2/";    

$dir = opendir($current_dir);        // Open the sucker

$files = array();
while ($files[] = readdir($dir));
sort($files);
closedir($dir);

foreach ($files as $file)
      if ($file <> "." && $file <> ".." && !preg_match("/^hide/i",$file))


$table_cell .= "<td><img src='".'weddings2/'. rawurlencode($file) ."'><br />$cfile</td>\n";


echo $table_cell;

是的,我知道我很蠢.Arghhh!

Answer 1

编辑:您的代码缺少大括号

你有

foreach (...)
      code
      code

它应该是

foreach (...) {
      code
      code
}

只需将代码放在$ parts和foreach循环之后的最后一个$ cfile之间,只需在循环中添加大括号,这样就可以放入更多代码.另请注意,如果两个代码段中的条件不同,则必须确定哪个一个使用或是否将它们组合成一个条件.

$current_dir = "$DOCUMENT_ROOT"."/weddings2/";    

$dir = opendir($current_dir);        // Open the sucker

$files = array();
while ($files[] = readdir($dir));
sort($files);
closedir($dir);

foreach ($files as $file) {

      //MANIPULATE FILENAME HERE, YOU HAVE $file...

      if ($file <> "." && $file <> ".." && !preg_match("/^hide/i",$file))
      echo "<td><img src='".'weddings2/'. rawurlencode($file) ."'><br />$cfile</td>\n";
}
