array within an array

I have an sql query which calls * rows from a table. Each row is an array of table field values. This is how I understand the heirachy $table_row_array[0] = $field_row_array[] $table_row_array[1] = $field_row_array[] $table_row_array[2] = $field_row_array[] Now $table_row_array is being drawn from the database via a while loop and an $a++, thus I do not have a name for $field_row_array- I just know that the value of each in $table_row_array is an array. How can I access the values within $filed_row_array[]? I want to do something like $table_row_array[0 [1]]; (the second value from the array that is the first of $table_row_array) I know this isnt the syntax Thanks in advance
