what is difference between -> and => in laravel

Question

This is the code where we have used -> and => .

But I always get confused, while writing code at that time which one to use and where.

So seeking its logic to easily remember it.

   $quan= $request->all();
   ChaiExl::create(['date'=>date('Y-m-d',strtotime($quan['dt'])),'quantity'=>$quan['quan']]);

return view('edit',['row'=>$row]);

Answer 1

-> and => are both operators.

The difference is that => is the assign operator that is used while creating an array.

For example: array(key => value, key2 => value2)

And -> is the access operator. It accesses an object's value

Answer 2

This is PHP syntax, not laravel specifics.

=> is for setting values in arrays:

$foobar = array(
    'bar' => 'something',
    'foo' => 222
);

or

$foobar = [
    'bar' => 'something',
    'foo' => 222
];

-> is used for calling class methods and properties:

class MyClass {

   public $bar = 'something';

   public function foo() {

   }

}
$foobar = new MyClass();
$foobar->foo();
echo $foobar->bar;
