How do I pass a variable coming from a form to make up an sql query? (ie=create table <VARIABLE>)

Form variables appear in two superglobal arrays: $_REQUEST, and either
$_GET or $_POST.  The element names appear as the indices of these arrays.

For example, if your form contained this element:
<input type='text' name='tableName'>

then the value of that input will appear in
$_REQUEST['tableName']

You can construct a string in several ways.  The following all result in
the same string:
$sql = sprintf("CREATE TABLE %s", $_REQUEST['tableName']);
$sql = "CREATE TABLE " . $_REQUEST['tableName'];
$sql = "CREATE TABLE {$_REQUEST['tableName']}";
