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

Array ( [0] => Array ( [technologies_id] => 1 [nom] => PHP [type_technologies_id] => 1 [nom_techno] => Developpement web ) [1] => Array ( [technologies_id] => 3 [nom] => ASP3 [type_technologies_id] => 1 [nom_techno] => Developpement web ) [2] => Array ( [technologies_id] => 5 [nom] => JavaScript [type_technologies_id] => 1 [nom_techno] => Developpement web ) [3] => Array ( [technologies_id] => 6 [nom] => CSS [type_technologies_id] => 1 [nom_techno] => Developpement web ) [4] => Array ( [technologies_id] => 7 [nom] => AJAX [type_technologies_id] => 1 [nom_techno] => Developpement web ) [5] => Array ( [technologies_id] => 17 [nom] => HTML [type_technologies_id] => 1 [nom_techno] => Developpement web ) ) Array ( [0] => Array ( [technologies_id] => 8 [nom] => Jquery [type_technologies_id] => 2 [nom_techno] => Frameworks web ) ) Array ( [0] => Array ( [technologies_id] => 22 [nom] => VB 6 [type_technologies_id] => 3 [nom_techno] => Developpement applicatif ) [1] => Array ( [technologies_id] => 23 [nom] => VB.NET [type_technologies_id] => 3 [nom_techno] => Developpement applicatif ) ) Array ( ) Array ( ) Array ( [0] => Array ( [technologies_id] => 28 [nom] => MySQL [type_technologies_id] => 6 [nom_techno] => SGDB(R) ) [1] => Array ( [technologies_id] => 30 [nom] => SQL Server Express [type_technologies_id] => 6 [nom_techno] => SGDB(R) ) [2] => Array ( [technologies_id] => 32 [nom] => SQLite [type_technologies_id] => 6 [nom_techno] => SGDB(R) ) [3] => Array ( [technologies_id] => 34 [nom] => Microsoft Access [type_technologies_id] => 6 [nom_techno] => SGDB(R) ) ) Array ( [0] => Array ( [technologies_id] => 39 [nom] => SQL [type_technologies_id] => 7 [nom_techno] => Langages d'interrogation de bases de donnees ) ) Array ( [0] => Array ( [technologies_id] => 46 [nom] => Windows [type_technologies_id] => 9 [nom_techno] => OS ) [1] => Array ( [technologies_id] => 49 [nom] => MAC OS [type_technologies_id] => 9 [nom_techno] => OS ) ) Array ( [0] => Array ( [technologies_id] => 54 [nom] => Merise [type_technologies_id] => 11 [nom_techno] => Methodologies ) )

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 1 '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 –  beegees Nov 1 '13 at 10:43
    
@beegees, what ever you want :) Put ' ' (space) for example or ',' (comma). $sep is this separator of the arrays. –  KryDos Nov 1 '13 at 10:45
    
Thank you KryDos, you're a Gentleman. Your code works great. bee –  beegees Nov 1 '13 at 10:52
    
recursive array you made. Really good answer. –  Alexander Nov 1 '13 at 11:12

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 1 '13 at 10:31
    
I think you code doesn't work. Thanks anyway –  beegees Nov 1 '13 at 10:50
    
I test this code before write this –  Akuma Nov 1 '13 at 10:52
    
Strangely, it doesn't work for me. Thanks again. –  beegees Nov 1 '13 at 10:53

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.

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

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

Thank you. I have a parse error with your code ? –  beegees Nov 1 '13 at 10:43
    
@beegees I'm sorry, I forgot foreach syntax. I've made proper corrections. –  namikiri Nov 1 '13 at 10:48
