You can convert an array to a string in Laravel by using the implode() function. Here's an example:
1 2 3 4 5  | 
$array = [1, 2, 3, 4, 5];
$string = implode(",", $array);
// Output: "1,2,3,4,5"
 | 
In this example, the implode() function takes two parameters - the separator (in this case ",") and the array that you want to convert to a string. The function then concatenates all the elements of the array into a single string, separated by the specified separator.
