Passing Array into a Function?

[WinterDragon]

How do I pass an array into a function? I mean how do I make a function to where it will accept arrays as arguments?

All you need to do is simply ensure that the array is in a variable then simply pass that variable to the function.

in the function make use of the is_array() function.

Essentially its the same as passing a normal variable to a function

Functions don't care what you pass em, so long as you pass the correct number of parameters they are fine.

Ok I got that part, but how do I return the array after the function finishes the process? Like I need the function to return an array, then how do I deal with the result afterwards?

function test($array) {
$array[0]++;
return $array;
}

doesn't work, neither does return array($array);
Any suggestions on this? Thanks.

in your function you can declare a variable as an array but using

$var = array();

or you can use $var[] = whatever

then when yo do return $var if it is an array then it'll automatically be returned as an array. TO make sure that it is an array do the following before you return the array

print_r($var)

If it is an array it'll display the array structure

Ok here is the lil' script...

<?php
$list = array("One", "Two", "One", "Two");
$item = "Two";
$items = deleteItem($list, $item);
foreach($items as $i) {
echo "$i<br>";
}
function deleteItem($one, $two) {
$check = array_search($two, $one);
unset($one[$check]);
$testing = $check;
return $testing;
}
?>

I tried $testing = $check(), but nothing returns, hrmmm what am I doing wrong? I've tried also different ways, but I won't just keep bluttering them out here... Sorry for so much bothering 😛

read up on the [man]extract/man function that may be what you are looking for.

this is a basic example of what it can do

    function myfunc ( $args ) {
        extact($args);
        echo $message;
    }

myfunc( array( 'message'=>'hello world' ) );

/// prints : hello world

function myfunc2 ( $args ) {
    extact($args);
    if ( $print_this ) {
        echo $message;
    }
}

myfunc2( array( 'message'=>'hello world', 'print_this'=>false ) );

/// prints nothing

ok, passing an array into a function is no problem, Thats easy for the argument for a function to be an array... but when I try to return the array inside the function, it does not do anything... How do I actually return all elements of the array AS an array?

[WinterDragon]

Oh I apologize, I am just stupid, I was trying to return something else, and not the array, works just fine like I had it the original time, HAHA! Sorry for the bother!

i've read the message but i was not satisfy...i used to program in VB and now i'm with php.
i used the extract function but it's not what i need.
Can't i pass an entired array and the function who recives the array, get the exact structure and data array i pass ????
thanks
