I have a PHP multidimensional array that looks like this:
[[1,45],[2,23],[3,37],[4,51],[5,18],[6,32],[7,29],[8,45],[9,37],[10,50]]
(Those numbers are stored as strings, not int)
What I want is to convert this multidimensional array to a string that teorically is stored like this:
$converted = "[[1,45],[2,23],[3,37],[4,51],[5,18],[6,32],[7,29],[8,45],[9,37],[10,50]]";
Literally all the array in one string
currently I have the array stored in a variable named $array
Use json_encode,
$array = [[1,45],[2,23],[3,37],[4,51],[5,18],[6,32],[7,29],[8,45],[9,37],[10,50]];
echo json_encode($array);
And if your numbers is string, you can convert them to int before json_encode,
$array = [["1", "45"], ["2", "23"], [3, 37], [4, 51], [5, 18], [6, 32], [7, 29], [8, 45], [9, 37], [10, 50]];
echo json_encode(array_map(function ($subArray) {
return array_map(function ($number) {
return intval($number);
}, $subArray);
}, $array));
echo json_encode(array_map(fn($item) => array_map('intval', $item), $array));
