Here is a good one using MySQL. See if you can find the array. $Result = mysql_Query( "SELECT Field1, Field2 " . "FROM Table " ); while( list( $Field1, $Field2 ) = mysql_Fetch_Row( $Result )) { echo( "Field1: $Field1 Field2: $Field2<BR>\n" ); } That will select field1 and field2 from Table, and paint them, one per row to the web browser. Do you see an array in there anywhere? Mysql_fetch_row() returns a number based array of the fields you request in your SELECT. list() copies the entries into a list of variables.
