PHP array convert each to string

Question

Simple question in PHP, how to convert this below array to be string?

print_r($_POST['cb']);

//result
Array ( [0] => Array ( [id] => 1 [tipe] => create ) [1] => Array ( [id] => 1 [tipe] => delete ) [2] => Array ( [id] => 2 [tipe] => read ) [3] => Array ( [id] => 2 [tipe] => delete ) )

I tried this below code but not working:

echo implode(", ", $_POST['cb']);

//result
Array
(
[0] => Array
    (
        [id] => 1
        [tipe] => read
    )

[1] => Array
    (
        [id] => 1
        [tipe] => update
    )

[2] => Array
    (
        [id] => 2
        [tipe] => update
    )

)

What I want is to get id and tipe for each array.

What you could is initialize an empty string and then loop through your arrays and add their elements to your initialized string like this :

$str = '';
foreach($arrs as $arr) { // $arrs is your $_POST['cb'] array
    foreach($arr as $item) {
        $str .= $item . ' ';
    }
}
echo $str;

Thanks for the answer, how about to save it to database? ex: INSERT INTO T_DATA(ID, CHKVALUE) VALUES('', '') <-- – HiDayurie Dave Mar 04 '17 at 06:12
if you need to save the data into database then what you need is to save them as a variables not a string for example $id = $_POST['id']. – Amr Aly Mar 04 '17 at 06:17
Would you give me an example? – HiDayurie Dave Mar 04 '17 at 06:21
for example `INSERT INTO CUSTOMERS (ID,NAME,AGE,ADDRESS,SALARY) VALUES (4,'$name', 25, '$address', 6500.00 );` – Amr Aly Mar 04 '17 at 06:27
I mean example in this case please. :) – HiDayurie Dave Mar 04 '17 at 06:28
Your data in this case is not easy to be stored in a variable it's better to structure your code so the submitted data will be a normal array and not a multidimensional array. i hope that makes sense. i have a question is that all your data submitted to your server? – Amr Aly Mar 04 '17 at 06:33
if so what you could do create your variables is `$id = $_POST['cb'][0]['id']` – Amr Aly Mar 04 '17 at 06:42

class StringBuilder {

    private $data;
    private $string;

    function __construct(array $data) {
        $this->data = $data;
    }

    public function get() {
        $this->parse();
        return $this->string;
    }

    private function parse() {
        foreach($this->data as $values) {
            $this->string .= $values['id'] . ' ' . $values['tipe'] . ' '; 
        }
        $this->string = trim($this->string);
    }
}

I think this would be the easiest way for you to achieve what you are attempting to do.

Available Methods:

__construct()
get()
