functions

Hi all happy holidays

I have recently came across functions and am wondering how i would grab the deatails from one funtion in order to have another run. Find this hard to explain but heres an example.

<?php

function funca()
{
$username="something";
$code="blah";
$database="blah";
}

function funcb()
{

$link=mysql_connect("localhost", "$username", "$code") or die ('I cannot connect to the database because: ' . mysql_error());

mysql_select_db ("$database");

$query = "SELECT blah blah";  

$result = mysql_query($query) or die(mysql_error());  

$row = mysql_fetch_assoc($result); 

mysql_close();
}

?>

this has me stumped am sure its easy if you know how lol

There are two main methods.
One is to use [man]return[/man] (generally preferable unless you have some reason to work some other way); the other is to pass by reference (that's also in the manual - I've mislaid just where Chapter 21, I think).

If you want to use the result of another function, then you must return something from the function -

function MySQLDetails() {
  // return connection details
  return "localhost-root-password";
}

function MyFunction() {
  $connDetails = MySQLDetails(); // stores mysql connection details in $connDetails
  $bits=split("-", $connDetails);
  $mysql_conn = mysql_connect($bits[0],$bits[1],$bits[2]);
}
