Create folder help

how to create folder name from user inputs with the folder permissions?

if users input the folder name from the form below, i wanna now create the folder from that folder name (if users enters space between the folder name then i want "_" to be included in between the names; like Folder_name)

<form id="form1" name="form1" method="post" action="create.php">
  <table width="29%" border="0" cellspacing="0" cellpadding="0">
    <tr>
      <td>Name :</td>
      <td><label>
        <input type="text" name="name" id="name" />
      </label></td>
    </tr>
    <tr>
      <td>&nbsp;</td>
      <td>&nbsp;</td>
    </tr>
    <tr>
      <td>&nbsp;</td>
      <td><label>
        <input type="submit" name="button" id="button" value="Submit" />
      </label></td>
    </tr>
  </table>
</form>

<?php

mkdir('/path/to/dir/' . str_replace(' ', '_', $_POST['name']), 0777);

?>

Of course you should do more validation that that (in case the user enters a / or other illegal character).

 

OK thanks for the code, and how would i remove off the unnecessary characters if users input that, and also, how to check if there's already the folder with same name, and show error message...

 

To check if it already exists:
