Coming to Laravel 5.5 is two brand new methods on the Collections class that will make debugging easier than ever before. These are dd and dump.
Pretend you have a simple collection setup and are piping it through a few filters:
collect([1,2,3])->map(function($i){
return $i * 2;
})->reject(function($i){
return $i < 3;
});
Knowing what happens in each step of the chain is can be difficult and now you’ll have the option to either “dump” it out at a certain point, or “dump and die”. For example:
collect([1,2,3])->map(function($i){
return $i * 2;
})->dump()->reject(function($i){
return $i < 3;
});
dump() outputs the results at that moment and then continues processing, here is the results when running that code:
Collection {#181 ▼
#items: array:3 [▼
0 => 2
1 => 4
2 => 6
]
}
dd() on the other hand stops the process immediately and dumps out the results:
collect([1,2,3])->map(function($i){
return $i * 2;
})->dd()->reject(function($i){
return $i < 3;
});
And the results:
array:3 [▼ 0 => 2 1 => 4 2 => 6 ]
These will be welcomed features in Laravel 5.5 and if you’d like to start using these today, Spatie released a 3rd party package named Collection Macros that includes both of these methods and a few additional helpers.
