Transform an array in String. Result => "array...array"

Question

I would like to transform this array in String with implode :

I tried like this :

$string_comp = implode($competences);

but I obtained this :

ArrayArrayArrayArrayArrayArray

Thanks in advance for your help

You have a multidimensional array, an array of arrays. Implode only works on 1 level of an array. — Ben Fortune, Nov 01 '13 at 10:26

Try this custom function :)

function multi_implode($sep, $array)
{
    $_array = array();

    foreach($array as $val)
    {
        if(is_array($val)) $_array[] = multi_implode($sep, $val);
        else $_array[] = $val;
    }

    return implode($sep, $_array);
}

Your implode not working because you are have a multi-array.

When I call this function, what separator have I to send ? thank you – David Nov 01 '13 at 10:43
@beegees, what ever you want :) Put ' ' (space) for example or ',' (comma). $sep is this separator of the arrays. – KryDos Nov 01 '13 at 10:45

You have an array of arrays. You must implode each subarray, like this:

foreach ($competences as $subArray)
{
    $string_comp .= implode($subArray);
}

@beegees I'm sorry, I forgot `foreach` syntax. I've made proper corrections. – namikiri Nov 01 '13 at 10:48

Try like this->

$array = array(1,2,3,4);
echo serialize($array);

// Prints

a:4:{i:0;i:1;i:1;i:2;i:2;i:3;i:3;s:3:4;}

Just use this:

$res = '';
foreach ($arr as $item) {
    $res .= implode('', $item);
}

Or in an one line: $str = implode(array_map('implode', $array)) – Akuma Nov 01 '13 at 10:31

To get output in a string formate use serialize() function of php you can unserialize() also as its previous state.

Depends on how you want to access it but personally, I'd just convert it to JSON with json_encode($myvar);. Or have a look at this answer provided on Stackoverflow: Multidimensional Array PHP Implode.
