Question

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

Answer 1

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.

Answer 2

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;}

Answer 3

Just use this:

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

Answer 4

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

Answer 5

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.

Answer 6

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

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