File splitter by nth row

I need to split a file into n separate files of about the same size. The way the file will be split is at every nth row, starting with the first row, that row will be cut and copied to it's corresponding new file so that each file has unique records. Any 'leftovers' will go into the last file. e.g.
Code:
>ls 
sample.txt
> cat sample.txt
aab
aac
aad
aae
aaf
aag
aah
aai
aaj
aak
aal
aam

'Run command' with n=4
Desired output:
Code:
>ls -l
sample.txt
sample1.txt
sample2.txt
sample3.txt
sample4.txt
>cat sample1.txt
aab
aae
aai
aam
>cat sample2.txt
aac
aag
aal
>cat sample3.txt
aad
aaj
>cat sample4.txt 
aaf
aah
aak

# sample4.txt picked up the "leftovers".

Thanks in advance.

mssql_fetch_row - Get row as enumerated array

SYNOPSIS
array mssql_fetch_row (resource $result) DESCRIPTION
mssql_fetch_row(3) fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0. Subsequent call to mssql_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows. PARAMETERS
o $result - The result resource that is being evaluated. This result comes from a call to mssql_query(3). RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 mssql_fetch_row(3) example <?php // Connect to MSSQL and select the database $link = mssql_connect('MANGOSQLEXPRESS', 'sa', 'phpfi'); mssql_select_db('php', $link); // Query to execute $query = mssql_query('SELECT [id], [quote] FROM [quotes] WHERE [id] = '42'', $link); // Did the query fail? if (!$query) { die('MSSQL error: ' . mssql_get_last_message()); } // Fetch the row $row = mssql_fetch_row($query); // Print the 'quote' echo 'Quote #' . $row[0] . ': "' . $row[1] . '"'; ?> The above example will output something similar to: Quote #42: "The answer to everything..." NOTES
Note This function sets NULL fields to the PHP NULL value. SEE ALSO
