Sort filenames alphabetically

[usamaalam]

Hello everybody,

Here's my code to scan a particular directory and show all files with a checkbox next to each filename. My client just want to show these filenames sorted alphabetically.

$dir = "../download/";
$i=0;
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
    print "<tr><td height='25'></td></tr>";
        while (($file = readdir($dh)) != false) {
            // print "filename: $file : filetype: " . filetype($dir . $file) . "\n";
            if(filetype($dir . $file)!='dir' and !in_array($file,$att))
            {
				$i++;
				//echo "";
				print "<tr><td class='caption'>" . "<a href='$dir$file'>" . $file . "</td>";
				if($_GET[id]=="admin")
					print"<td class='caption'><input type='checkbox' name='chk$i' value='$file'></td>";
				else
					print"<td class='caption'></td>";
			};
        }
    closedir($dh);
    }
}

Thanks.

When you have all the file names in an array, then use the sort function:

Can you tell me how to create a dynamic array in PHP as I don't know how many files will be present in folder.

Thanks.

All arrays in PHP are dynamic, just addand remove as and when you require.

lets work with this:

            if(filetype($dir . $file)!='dir' and !in_array($file,$att))
            {
				$i++;
				//echo "";
				print "<tr><td class='caption'>" . "<a href='$dir$file'>" . $file . "</td>";
				if($_GET[id]=="admin")
					print"<td class='caption'><input type='checkbox' name='chk$i' value='$file'></td>";
				else
					print"<td class='caption'></td>";
			};

First of all, I am not sure exactly why the last semicolon is there. so I'm going to take it out of mine.

Here's an idea of what to do:

            if(!isdir($file) && !in_array($file,$att))
            {
		$filearray[] = $file;
	    }

After that you can display them.

I populated a two dimensional array with filenames and directory names. Its working fine, I checked by printing them on page. But the sort function is not working well. How can I sort a two dimensional string array with respect to first dimension?

Thanks.

Which could have been found in NoteMe's link also.
