[SOLVED] array()

[iversonm]

probably easy answer, so if you have

 

your database page with this array

function fruits(){

$fruits = array (

    "fruits"  => array("a" => "orange", "b" => "banana", "c" => "apple"),

    "numbers" => array(1, 2, 3, 4, 5, 6),

    "holes"  => array("first", 5 => "second", "third")

);

and the function returns fruit soo

return $fruit;

}

 

so then if i i want to display lets say banana  and only banana how owuld i do that

i was thinking something like

$fruits=$database->fruits();

echo $fruits['fruits']['b'];

but that doesnt work? any help would be awesome

I'm not sure what you mean with a database, because this is everything but.

 

you would call the function in a way such as

 

$fruits = fruits();
echo $fruits['fruits']['b'];

 

but you typo'd return $fruits; in the function

[iversonm]

well see the function fruits is on a different page under the class database thats why i would user $database->fruits()

 

[iversonm]

i figured it out, when selecting the data from the database i was using mysql_fetch_row instead of mysql_fetch_array so it was returning the data

Ah, it's a class named database.

 

Then you would do

 

$database = new database();
$fruits = $database->fruits();
echo $fruits['fruits']['b'];

 

But if you are using php5 (and I hope you are) I would add the word public in front of function on the method declaration.

 

public function fruits()

 

It's just good practice to assign access specifiers in oop.

yes, i am using Php 5 but what is the reasoning behind using public??

Read up on OOP visibility indicators. >_<  'public' basically means that the method can be called from outside of the class.  Protected means it can be used inside the class and passed down to all subclasses, and private means only the containing class can use it.

[iversonm]

but i thought all function were public by default without having to specify they are public

They are, it's just good practice to always specify it.
