using function to select database?


Recommended Posts

I'm trying to set-up a function for me to choose which database to use, by place a call to the function with either number 1 or 2.



$db_name="zyquo_donors"; // Database name 
$tbl_name="donors"; // Table name 

mysql_connect("$host", "$username", "$password")or die("cannot connect");

function db_select($db="1"){
mysql_select_db("$db_name")or die("cannot select DB");
mysql_select_db("$db_name2")or die("cannot select DB");


and on the page I have:




The result is:

cannot select DB

My best response would be to learn how to write functions.



Functions can be made in a few ways, but usually you need to either echo or return the result.


function db_select($db){
if($db == 1) {
$myselect = mysql_select_db("$db_name")or die("cannot select DB");
} elseif($db == 2) {
$myselect = mysql_select_db("$db_name2")or die("cannot select DB");
} else {
$myselect = "There was a problem selecting a database";

return $myselect;


The above is just a fast example.
