    <p>I want to create a directory structure based on a partition map, as in these examples. I've tried various approaches with failure. Recursive programming makes my brain hurt!</p> <p>Example 1</p> <pre><code>$partitionMap = '#/#'; //An example of two levels deep myfolder/0 myfolder/1 myfolder/2 ... myfolder/f myfolder/f/0 myfolder/f/1 myfolder/f/2 myfolder/f/3 ... </code></pre> <p>Example 2</p> <pre><code>$partitionMap = '#/#/#'; //An example of three levels deep myfolder/a myfolder/a/4 myfolder/a/4/f </code></pre> <p>Example 3</p> <pre><code>$partitionMap = '#/##/###'; //An example of three levels deep myfolder/0 myfolder/1 myfolder/2 ... myfolder/a/00 myfolder/a/01 myfolder/e/02 myfolder/e/03 ... myfolder/e/03/af0 myfolder/e/03/af1 myfolder/e/03/af2 myfolder/e/03/af3 </code></pre> <p>The # is a hexadecimal placeholder presenting 0-F as you can see above.</p> <p>So I need something that works like this..</p> <pre><code>$partitionMap = '#/##'; makeFoldersRecursive( './myfolder', $partitionMap ); function makeFoldersRecursive( $path, $pmap ){ $pmapArr = explode( '/', $pmap ); $numNibbles = strlen( $pmapArr[0] ); //Get hex folder count but in dec, # = 16, ## = 256, ### = 4096 $folder_count_this_level = pow( 16, $numNibbles ); for($i=0; $i&lt;$count; $i++ ) { //Get left padded hex folder name from $i $folder = sprintf("%0" . $numNibbles . "s", dechex($i)); mkdir( $path . DIRECTORY_SEPARATOR . $folder , 0755 ); if( array_key_exists( 1, $pmapArr ) ) { $passMap = $pmapArr; array_shift( $pmapArr ); makeFoldersRecursive( $path . DIRECTORY_SEPARATOR . $folder, $passMap ); } } } </code></pre> <p>There's got to be a more elegant way of doing this, Any help would be appreciated!</p>

    1. COYou know that `mkdir()` takes a recursive param right? http://php.net/manual/en/function.mkdir.php `mkdir('/path/to/create', 0755, true);`

    2. COYes, but I don't see how using it helps with what I'm trying to accomplish.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
