without foreach, how can i turning an array like the following

array("item1"=>"object1", "item2"=>"object2",......."item-n"=>"object-n");

to a string like this:

item1='object1', item2='object2',.... item-n='object-n'

i thought about implode() already, but it doesn't implode the key with it...

if foreach it necessary, is it possible to not nest the foreach?

my solution used nested foreach which is not what i wanted

EDIT: i've changed the string

How nested foreach would be necesarry? – Shubham Jul 11 '12 at 7:14
What are you attempting? Why do you have those constraints? – Madara Uchiha Jul 11 '12 at 7:27
this was my database class for web app i'm building, i don't want it to look messy since it's already populated with a bunch of foreach and for-loop all together – Tom91136 Jul 11 '12 at 7:30
@downvoter, why downvote? – Tom91136 Jul 11 '12 at 7:38

and another way:

$input = array('item1' => 'object1', 'item2' => 'object2', 'item-n' => 'object-n');
$output = implode(', ', array_map(function ($v, $k) { return $k . '=' . $v; }, $input, array_keys($input)));

or:

$output = implode(', ', array_map(function ($v, $k) { return sprintf("%s='%s'", $k, $v); }, $input, array_keys($input)));

function key_implode(&$array, $glue) {
    $result = "";

    foreach ($array as $key => $value) {
        $result .= $key . "=" . $value . $glue;
    }

    return substr($result, (-1 * strlen($glue));
}

Usage:

$str = key_implode($yourArray, ",");

You could use http_build_query, like this:

<?php
  $a=array("item1"=>"object1", "item2"=>"object2");
  echo http_build_query($a,'',', ');
?>

Output:

item1=object1, item2=object2

is it possible to make the object1 into 'object1' – Tom91136 Jul 11 '12 at 7:23
Never used the other parameters of http_build_query. – shiplu.mokadd.im Jul 11 '12 at 7:38

I would use serialise() or json_encode().

While it won't give your the exact result string you want, it would be much easier to encode/store/retrieve/decode later on.

i need the string to look exactly like that – Tom91136 Jul 11 '12 at 7:14

Using array_walk

$a = array("item1"=>"object1", "item2"=>"object2","item-n"=>"object-n");
$r=array();
array_walk($a, create_function('$b, $c', 'global $r; $r[]="$c=$b";'));
echo implode(', ', $r);
