Question

I just found this in a laravel bundle that I just installed, and really have no idea what with() is… as it isn’t declared any where

public static function of($query)
{
    $ins = with(new static); // What is with(new static) ?
    $ins->save_query($query);
    return $ins;
}

Answer 1

with() is not a statement but a user defined function in Laravel framework.

From laravel documentation :

490: /**
491:  * Short-cut for constructor method chaining.
492:  *
493:  * @param  mixed  $object
494:  * @return mixed
495:  */
496: function with($object)
497: {
498:     return $object;
499: }
