help using the mkdir in php5 to create a directory

mkdir help

[rodriguez1804]

Ok, I seem to be having loads of trouble getting the mkdir function to work inside a function. Particularly, this following function:

function directoryListingCheck( $path = '.', $level = 0 )
{
 $myusername=$_POST['myusername'];
 $myusername=stripslashes($myusername); //define 'myusername
 $myusername=mysql_real_escape_string($myusername); 
 $lettermyusername = substr($myusername, 0,1); //get first character of string
 $lettermyusername = stripslashes(htmlspecialchars($lettermyusername));
 $ignore = array( '.', '..' ); // Directories to ignore when listing output.
 $dh = @opendir( $path ); // Open the directory to the handle $dh
 $i=0;
 while( (false !== ( $file = readdir( $dh ) )) && ($i<=36)) // Loop through the directory
 //$file=readdir($dh); 
 {
 if( !in_array( $file, $ignore ) ) // Check that this file is not to be ignored
 { 
 $spaces = str_repeat( '&nbsp;', ( $level * 5 ) ); // Indent spacing for better view
 if(is_dir( "$path/$file" ) ) // Show directories only
 {
  // Re-call this same function but on a new directory.this is what makes function recursive.    
  $firstLetterDir=substr($file,0,1);
    
  //echo $firstLetterDir;
  
  if($lettermyusername == $firstLetterDir){
  echo "match found";
  mkdir("$DOCUMENT_ROOT/users/$lettermyusername/$myusername");
  break;
 }else{die("could not create the folder");}
 
 }
 }
 $i++;
 }
 closedir( $dh ); // Close the directory handle
}

What I want the function to do is to match the input username's first character to the corresponding first letter in the alphabet(lower case). The script works fine, but somehow I am not using the mkdir correctly to create the corresponding directory.

Example to better explain:
('users' in the path name above contains folders named a-z lower case)
1.) user inputs --> john (username)
2.) function checks folder name and matches it to 'j' in username first character
3.) mkdir creates path/to/users/j/john,

What am I doing wrong? Any help would be greatly appreciated! Thanks.

Ok, so I found my first mistake (using == instead of = for char values), but it 's still not creating the directory. I ll keep working on it.

glad to be of service ;)

haven't read your original post -- if it wasn't just a typo, mind sharing the final solution in case someone else runs into the same problem?

Just in case anybody is having a similar problem, here is the final version that I was able to get working for me. Cheers!

function directoryListingCheck( $path = '.', $level = 0 )
{
 $myusername=$_POST['myusername'];
 $myusername=stripslashes($myusername); //define 'myusername
 $myusername=mysql_real_escape_string($myusername); 
 
 $lettermyusername = substr($myusername, 0,1); //get first character of string
 $lettermyusername = stripslashes(htmlspecialchars($lettermyusername));
 $ignore = array( '.', '..' ); // Directories to ignore when listing output.
 $dh = @opendir( $path ); // Open the directory to the handle $dh
 while( (false !== ( $file = readdir( $dh ) ))) // Loop through the directory 
 {
  if( !in_array( $file, $ignore ) ) // Check that this file is not to be ignored
  { 
  $spaces = str_repeat( ' ', ( $level * 5 ) ); // Indent spacing for better view
  if(is_dir( "$path/$file" ) ) // Show directories only
  {
   
   //get first letter of directory    
   $firstLetterDir=substr($file,0,1);
        
   if($lettermyusername == $firstLetterDir){
   mkdir("../../example/path/$lettermyusername/$myusername");
   }
  }
  }
 }
 closedir( $dh ); // Close the directory handle
}
