Php making dynamic new directory

[Bob_PHP_Builder]

hi there i was just wondering if anyone could direct me on how to create a directory on the server each time files are uploaded to the server. i know its something to do with mkdir but im just new on all this.. a tutorial or help would be much appreciated..

Thank you

Er, why a tutorial. mkdir() is a simple construct:

mkdir($newpath, 0777);

Creates a publically readable directory. Be careful with the permisions value and make it only what you need. It's always better to be safe than sorry. For more information on possible values check out the chmod() section of the PHP manual at www.php.net/manual/en/function.chmod.php

ok. im cool with that now just got a problem with each new session.. is there any way to like read which was the last directory created and start from that point.. would i use an array..
Thanks

Well assuming you create then in sort order then dir() is what you need. This will read your directory. Simply get the last entry. Be careful though, dir returns a class not an array so read up on it first in the PHP manual. The alternative would be to store the last directory used in a database/file or cookie(yuck!).

how would i get the $qva part of the extension to work

            $num_image=10000+1;
$qva=$num_image;
$mkdir($qva, 0777);


if(file_exists(dec.$qva.$file_name)){
           echo "File ($file_name) already exists <br>";

Sorry, not sure what your are asking?

im new to this
basically i want $qva to add a new directory for each time files are added and i can't seem to get my head around what to do...
Thanks

<?php

$dec ="Photos/";
$num_files =1;
$file_bytes =5120000000;
$file_allowed = array(".jpg",".jpeg",".png",".zip",".tiff");

if(!is_dir("$dec")) 
{
die ("Error: ");
}

if (!is_writeable("$dec"))
{
die ("Error: ");
}

if (isset($_POST['upload_form']))
{
echo "<h2> The Following files have been upload </h2>";

 $num_image=10000+1;
$qva=$num_image;
$mkdir($qva, 0777);

	for ($i = 1; $i <= $num_files; $i++) {


		$new_file = $_FILES['file'.$i];
		$file_name = $new_file['name'];
		$file_name = str_replace(' ', '_', $file_name);
		$file_tmp = $new_file['tmp_name'];
		$file_size = $new_file['size'];

		if (!is_uploaded_file($file_tmp))
		{
			echo "File $i: There was no Photo selected <br>";
		}else{
			$ext= strrchr ($file_name,'.');


			if (!in_array(strtolower($ext), $file_allowed))
			{
			echo "File $i: ($file_name) INvalid Extension <br>";

			}else{


			if ($file_size> $file_bytes)
			{
			echo "File $i: ($file_name) Failed to upload. File must be lower than ($file_bytes)";

			}else{


			if(file_exists(dec.$qva.$file_name)){
			echo "File $i: ($file_name) already exists <br>";
			}else{


			if (move_uploaded_file($file_tmp, $dec.$qva.$file_name)) 
			{
			echo "File $i: $file_name Uploaded <br>";

			}else{

			echo "File $i; Failed to upload <br>";
				}

			}
		}
	}
}

}

echo "»<a href=\"$_SERVER[PHP_SELF]\">back</a>";

}else{
?>

<?

echo " <h2>Select Photos </h2>
       Max file size = ". $size_bytes / 1024 ." KB";
echo " <form method=\"post\" action=\"$_SERVER[PHP_SELF]\" enctype=\"multipart/form-data\">";
       // show the file input field based on($num_files).


       for ($i = 1; $i <= $num_files; $i++) {
           echo "File $i: <input type=\"file\" name=\"file". $i ."\"><br>";
       }
echo " <input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"$size_bytes\">
       <input type=\"submit\" name=\"upload_form\" value=\"Upload Now!\" >
       </form>";

}

?>

$mkdir($qva, 0777);

Drop the $ - it's a function not a variable.

Also, this will create a directory in the current path. So make sure your current path is what you want or add the path to $qva. You should also check the return value from mkdir - it returns false if it can't create the directory.
