Laravel - Collections - Method Implode

The implode method joins items in a collection. Its arguments depend on the type of items in the collection. If the collection contains arrays or objects, you should pass the key of the attributes you wish to join, and the "glue" string you wish to place between the values:

    
    $collection = collect([
        ['account_id' => 1, 'product' => 'Desk'],
        ['account_id' => 2, 'product' => 'Chair'],
    ]);
    
    $collection->implode('product', ', ');
    
    // Desk, Chair
	

If the collection contains simple strings or numeric values, you should pass the "glue" as the only argument to the method:

    
    collect([1, 2, 3, 4, 5])->implode('-');
    
    // '1-2-3-4-5'
