passing array variables into function

[V]

I'm experimenting with arrays and functions. The code I made is,

 

function list_items() {

$fruits = array('apples' => 'red',
			'bananas' => 'yellow',
			'grapes' => 'purple');

foreach($fruits as $fruit_key => $fruit_value) {
echo "$fruit_key are $fruit_value<br />";
}


$drinks = array('Soda' => 'kids',
			'Coffee' => 'adults',
			'Alcohol' => 'happy fun times');

foreach($drinks as $drinks_key => $drinks_value) {
echo "$drinks_key is for $drinks_value<br />";
}

}


list_items();

 

 

so it lists both fruits and drinks but I'm trying to learn how to list just one category of items. I tried

 

list_items($fruits, $drinks)  in the function and called it as list_items($drinks);  to list just the drinks but that just gives errors.. Can someone please tell me the correct way to achieve this?

function list_items($type)

{

if($type == 'fruit || $type == 'both')

{

do fruity stuff

}

if($type == 'drinks' || $type == 'both')

{

do drinky stuff

}

}

 

list_type('fruit');

Thank you for the script! I'm kind of confused. What is 'both'? Will I need to create an array for it? and the list_type('fruit') function, I didn't have that before.

 

Sorry for being a noob..

You should be defining the arrays outside of the function and then passing the array you want to echo into the function:

<?php
function list_items($ary) {
    foreach($ary as $key => $value) {
echo "$key is for $value<br />";
    }
}

$fruits = array('apples' => 'red',
			'bananas' => 'yellow',
			'grapes' => 'purple');
$drinks = array('Soda' => 'kids',
			'Coffee' => 'adults',
			'Alcohol' => 'happy fun times');
list_items($fruits);
list_items($drinks);
?>
