foreach() question

fontener

let's say I have an array( 1=>something, 2=>else, 3=>entirely)

I want to use the foreach element in the array, return the other elements in the array..

so 1 will return 2 and 3, 2 will return 1 and 3, and 3 will return 1 and 2... this array may contain two to dozens of elements at a given time

how do i do this?

dagon

care to explain that some other way, makes no sense to me

foreach element in the array I want to retrieve the other elements in the array.. basically im building a relationship between them in the database...

so lets say i have a form with a list of usernames.. you can check multiple users and submit to 'form a 'relationship' or 'family' if you will ...

so lets say the form returns an array like so : array(1=>David, 2=>Mike, 3=>Carol)

so for David i want to insert Mike and Carol into his 'family' column in the database...

for Mike i want to insert Carol and David... etc

but i dont want to insert themselves into their own 'family' field...

inside the foreach loop check the array key against the id i assume you have some how,if its a match don't do what ever, other wise do do what ever.

i'm more confused, how about some code.
id=which array key you want to exclude

fontener

$array = array(1=>Mike, 2=>David, 3=>Carol);

foreach ($array as $key => $value){

insert $array[keys] where $array[key] !=$key <--- *NOT ACTUAL CODE but the general idea of what im looking for

}

dagon

$array = array(1=>Mike, 2=>David, 3=>Carol);

foreach ($array as $key => $value){

if($key !=?????????????){
//do what ever
{

}

how are you defining what to exclude?

fontener

im probably making this harder than it should be.. maybe it's the late hours..

foreach($array as $key => $value)

insert {all elements of array} into {users table} {family column} EXCEPT {array element that is equal to $value

<?php

$a = array(1=>David, 2=>Chris, 3=>Nina);

function mycallback($input_var_inner) { 
    global $var_to_pass; 
    return ($input_var_inner!=$var_to_pass) ? true : false; 
    }

function myfilter($input_var_outer,$param) { 

global $var_to_pass; 
$var_to_pass = $param; 

$return_arr = array_filter($input_var_outer,'mycallback'); 
//re-key if you want 
//$return_arr = array_merge(array(),$return_arr); 
return $return_arr; 

} 
foreach($a as $key=>$value){
$exclude = $value; 

//remove elements from array that are equal to current_value 
$b = myfilter($a,$exclude); 

echo "<pre>"; 
print_r($b); 
echo "</pre>"; 
}
?>
