提问by Ivan M
i am coding a simple doc managing script and need to get the file size and file type /file or folder/ in a table. somehow it doesn't work into the mention directory. please help if possible:
我正在编写一个简单的文档管理脚本，需要在表格中获取文件大小和文件类型/文件或文件夹/。不知何故，它不适用于提及目录。如果可能，请帮助：
<?php
$path = "./documents";
$dh = dir($path);
while( ($file=$dh->read()) )
{
if( $file=="." || $file=="..")continue;
echo "<tr><td><a href='download.php?f=$file' title='Click to Open/Download'>$file</a></td>";
echo "<td>";
echo (is_file($file))? "<img src='file.jpg'/> FILE" : "<img src='folder.jpg'/> FOLDER ";
echo "</td><td>" .filesize($file)."</td>";
echo "<td><input type='checkbox' name='delete[]'/></td></tr>";
}
?>
it does actually has 2 errors - one the file size doesn't work for the location, if i change it to path to "." - everything is ok, but if i try to change to the folder where i need it /documents ...all goes bad, and secondly - it doesn't take the right icon file as well, same type of problem. thank you
它实际上有 2 个错误 - 一个文件大小不适用于该位置，如果我将其更改为路径“。” - 一切正常，但如果我尝试更改到我需要它的文件夹 /documents ...一切都会变坏，其次 - 它也没有采用正确的图标文件，同样类型的问题。谢谢你

Problem is, $fileis only the filename without the directory prefix, so checking on it won't work. One way would be to have a variable with the absolute filename (say $realfile). You'd then have to alter your code and use this variable for the file checks:
问题是，$file只有没有目录前缀的文件名，所以检查它是行不通的。一种方法是使用具有绝对文件名的变量（例如$realfile）。然后，您必须更改代码并使用此变量进行文件检查：
<?php
$path = "./documents";
$dh = dir($path);
while(($file=$dh->read()) !== false) {
if( $file=="." || $file=="..") continue;
// have a new variable for the real filepath
$realfile = $path . "/" . $file;
echo "<tr><td><a href='download.php?f=$file' title='Click to Open/Download'>$file</a></td>";
echo "<td>";
echo (is_file($realfile))? "<img src='file.jpg'/> FILE" : "<img src='folder.jpg'/> FOLDER ";
echo "</td><td>" .filesize($realfile)."</td>";
echo "<td><input type='checkbox' name='delete[]'/></td></tr>";
}
?>
