Think of it this way: $conf['db'] = "testdb"; Now, when you try to assign something to $conf['db']['host'] the $conf['db'] part is "testdb", what would "testdb"['host'] be? Since $cond['db'] is a string, the 'host' index of this string is the same as "testdb"[0] which is the first position of the string. So when you do: $conf['db']['host'] = "dbhost"; You end up with, "destdb", because there is only room for the first character of "dbhost" in the $conf['db'][0] slot. -Rasmus
