multidimensional array to simple array

Question

I have an array like this

array(5) { 
    [0]=> array(2) { [0]=> string(5) "REFER" [1]=> string(12) "Não Sócios" } 
    [1]=> array(2) { [0]=> string(5) "REFER" [1]=> string(12) "Não Sócios" } 
    [2]=> array(2) { [0]=> string(5) "REFER" [1]=> string(12) "Não Sócios" } 
    [3]=> array(2) { [0]=> string(5) "REFER" [1]=> string(12) "Não Sócios" } 
    [4]=> array(2) { [0]=> string(5) "REFER" [1]=> string(12) "Não Sócios" } 
}

and want to transform this array into an array like this

array("REFER, Não Sócios", "REFER, Não Sócios", "REFER, Não Sócios", "REFER, Não Sócios", "REFER, Não Sócios");

is that possible? if so, how can i do it? thanks in advance

Yes. Assuming that array is called $refer -

$new_refer = array_map(function($val) {
    return implode(', ', $val);
}, $refer);

Using parray_map you iterate over the elements and construct a new array with values returned from the callback function. Inside that function i'm using implode to combine the values of each element (which is an array in itself) and glue them with ', '.

You can do it with array_map for example:

$r = array_map(function($v) { return $v[0] . ', ' . $v[1]; }, $source_array);

here's a way you can do it:

$a = [
    [ 0 => "REFER", 1 => "Nao Socios" ] ,
    [ 0 => "REFER", 1 => "Nao Socios" ] , 
    [ 0 => "REFER", 1 => "Nao Socios" ] , 
    [ 0 => "REFER", 1 => "Nao Socios" ] ,
    [ 0 => "REFER", 1 => "Nao Socios" ] 
];
$res = [];

foreach ($a as $k => $v) {
    $res[] = $v[0];
    $res[] = $v[1];
}
var_dump($res);
