雄辩的 laravel: 如何从 a-> get()获得行计数

Answer has been updated

count is a Collection method. The query builder returns an array. So in order to get the count, you would just count it like you normally would with an array:

$wordCount = count($wordlist);

If you have a wordlist model, then you can use Eloquent to get a Collection and then use the Collection's count method. Example:

$wordlist = Wordlist::where('id', '<=', $correctedComparisons)->get();
$wordCount = $wordlist->count();

There is/was a discussion on having the query builder return a collection here: https://github.com/laravel/framework/issues/10478

However as of now, the query builder always returns an array.

Edit: As linked above, the query builder now returns a collection (not an array). As a result, what JP Foster was trying to do initially will work:

$wordlist = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)
->get();
$wordCount = $wordlist->count();

However, as indicated by Leon in the comments, if all you want is the count, then querying for it directly is much faster than fetching an entire collection and then getting the count. In other words, you can do this:

// Query builder
$wordCount = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)
->count();


// Eloquent
$wordCount = Wordlist::where('id', '<=', $correctedComparisons)->count();

Direct get a count of row

Using Eloquent

 //Useing Eloquent
$count = Model::count();


//example
$count1 = Wordlist::count();

Using query builder

 //Using query builder
$count = \DB::table('table_name')->count();


//example
$count2 = \DB::table('wordlist')->where('id', '<=', $correctedComparisons)->count();

Its better to access the count with the laravels count method

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

also, you can fetch all data and count in the blade file. for example:

your code in the controller

$posts = Post::all();
return view('post', compact('posts'));

your code in the blade file.

\{\{ $posts->count() }}

finally, you can see the total of your posts.

//controller $count = Post::count(); return view('post', compact('count'));

//blade \{\{$count}}

or //controller $posts = Post::all(); return view('post', compact('posts'));

//blade\{\{count($posts)}}
