{
$names = array();
$password = array();


$connect = @mysql_connect("mysql11.000webhost.com",$dbusername,$dbpassword) or die("Could Not Connect");
@mysql_select_db ($dbname) or die("Could not find DataBase");


$query = mysql_query("select * from users");
$numrows = mysql_num_rows($query);

if ($numrows > 0){

while($row = mysql_fetch_assoc($query)){

$names[] = $row["uname"];
$password[] = $row["password"];
$id = $row["id"];

}
$return = array($names,$password,$id);

I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually. 

the results i am trying to generate is that each item in generated array.

Array to convert

array(
    "account" => array(
        "login",
        "register",
        "logout",
        "edit",
    ),
    "p" => array( 
        "report",
    ),
    "array1.0" => array( 
        "array2.0" => array(
            "array3.0",
            "array3.1
        ),
        "array2.1",
    ),

generating the array will look like this

 

Array ( 
[0] => account 
[1] => account/login 
[2] => account/register 
[3] => account/logout 
[4] => account/edit 
[5] => p 
[6] => p/report 
[7] => array1.0 
[8] => array1.0/array2.0
[9] => array1.0/array2.0/array3.0
[10] => array1.0/array2.0/array3.1
[11] => array1.0/array2.1

)

The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array. 

 

is there a math function that give you an integer value when u divide 2 numbers?
ie in 7/3  i just want 2 as a result not floating number.
thanks in advance.

Hello Everyone,

I'm a newbie trying to improve my script below.
The script works fine but I would like to add the 3 radio buttons computations enhancements
Ergo,  if a user chooses 'Matte Paper" a 10% would be added to the Price Quote result.
If a user chooses ' Gloss Paper,  a 10% would be added to the Price Quote result.
If a user chooses 'Canvas" , a 20 % would be added to the Price Quote result.
If someone could assist with the math or post me a helpful link it would be greatly appreciated.
Thank you.

Paul from Melbourne, Australia.
