4blank(collect());
5 
6// true
7 
8blank(0);

1$value=cache('key');
2 
3$value=cache('key','default');

You may add items to the cache by passing an array of key / value pairs to the function. You should also pass the number of seconds or duration the cached value should be considered valid:

1cache(['key'=>'value'],300);
2 
3cache(['key'=>'value'], now()->addSeconds(10));

class_uses_recursive()

Theclass_uses_recursive function returns all traits used by a class, including traits used by all of its parent classes:

collect()

Thecollect function creates acollection instance from the given value:

1$collection=collect(['taylor','abigail']);

config()

Theconfig function gets the value of aconfiguration variable. The configuration values may be accessed using "dot" syntax, which includes the name of the file and the option you wish to access. A default value may be specified and is returned if the configuration option does not exist:

1$token=csrf_token();

dd()

Thedd function dumps the given variables and ends execution of the script:

1dd($value);
2 
3dd($value1,$value2,$value3,...);

If you do not want to halt the execution of your script, use thedump function instead.

dispatch()

Thedispatch function pushes the givenjob onto the Laraveljob queue:

1dispatch(new App\Jobs\SendEmails);

dispatch_now()

Thedispatch_now function runs the givenjob immediately and returns the value from itshandle method:

1$result=dispatch_now(new App\Jobs\SendEmails);

dump()

Thedump function dumps the given variables:

1$env=env('APP_ENV');
2 
3// Returns 'production' if APP_ENV is not set...
4$env=env('APP_ENV','production');

If you execute theconfig:cache command during your deployment process, you should be sure that you are only calling theenv function from within your configuration files. Once the configuration has been cached, the.env file will not be loaded and all calls to theenv function will returnnull.

event()

Theevent function dispatches the givenevent to its listeners:

1event(newUserRegistered($user));

factory()

Thefactory function creates a model factory builder for a given class, name, and amount. It can be used whiletesting orseeding:

1$value=old('value');
2 
3$value=old('value','default');

optional()

Theoptional function accepts any argument and allows you to access properties or call methods on that object. If the given object isnull, properties and methods will returnnull instead of causing an error:

1returnoptional($user->address)->street;
2 
3{!!old('name', optional($user)->name)!!}

Theoptional function also accepts a Closure as its second argument. The Closure will be invoked if the value provided as the first argument is not null:

1returnoptional(User::find($id),function($user){
2returnnewDummyUser;
3});

policy()

Thepolicy method retrieves apolicy instance for a given class:

1$policy=policy(App\User::class);

2 
3returnredirect('/home');
4 
5returnredirect()->route('route.name');

report()

Thereport function will report an exception using yourexception handler'sreport method:

1report($e);

request()

Therequest function returns the currentrequest instance or obtains an input item:

1$request=request();
2 
3$value=request('key',$default);

rescue()

Therescue function executes the given Closure and catches any exceptions that occur during its execution. All exceptions that are caught will be sent to yourexception handler'sreport method; however, the request will continue processing:

1returnrescue(function(){
2return$this->method();
3});

You may also pass a second argument to therescue function. This argument will be the "default" value that should be returned if an exception occurs while executing the Closure:

1returnrescue(function(){
2return$this->method();
3}, false);
4 
5returnrescue(function(){
6return$this->method();
7},function(){
8return$this->failure();
9});

resolve()

Theresolve function resolves a given class or interface name to its instance using theservice container:

1$api=resolve('HelpSpot\API');

response()

Theresponse function creates aresponse instance or obtains an instance of the response factory:

1returnresponse('Hello World',200,$headers);
2 
3returnresponse()->json(['foo'=>'bar'],200,$headers);

retry()

Theretry function attempts to execute the given callback until the given maximum attempt threshold is met. If the callback does not throw an exception, its return value will be returned. If the callback throws an exception, it will automatically be retried. If the maximum attempt count is exceeded, the exception will be thrown:

1returnretry(5,function(){
2 // Attempt 5 times while resting 100ms in between attempts...
3},100);

session()

Thesession function may be used to get or setsession values:

1$value=session('key');

You may set values by passing an array of key / value pairs to the function:

1session(['chairs'=>7,'instruments'=>3]);

The session store will be returned if no value is passed to the function:

1$value=session()->get('key');
2 
3session()->put('key',$value);

tap()

Thetap function accepts two arguments: an arbitrary$value and a Closure. The$value will be passed to the Closure and then be returned by thetap function. The return value of the Closure is irrelevant:

1$user=tap(User::first(),function($user){
2$user->name='taylor';
3 
4$user->save();
5});

If no Closure is passed to thetap function, you may call any method on the given$value. The return value of the method you call will always be$value, regardless of what the method actually returns in its definition. For example, the Eloquentupdate method typically returns an integer. However, we can force the method to return the model itself by chaining theupdate method call through thetap function:

1$user=tap($user)->update([
2'name'=>$name,
3'email'=>$email,
4]);

To add atap method to a class, you may add theIlluminate\Support\Traits\Tappable trait to the class. Thetap method of this trait accepts a Closure as its only argument. The object instance itself will be passed to the Closure and then be returned by thetap method:

1return$user->tap(function($user) {
2//
3});

throw_if()

Thethrow_if function throws the given exception if a given boolean expression evaluates totrue:

1throw_if(!Auth::user()->isAdmin(),AuthorizationException::class);
2

4!Auth::user()->isAdmin(),
5AuthorizationException::class,
6'You are not allowed to access this page'
7);

throw_unless()

Thethrow_unless function throws the given exception if a given boolean expression evaluates tofalse:

1throw_unless(Auth::user()->isAdmin(),AuthorizationException::class);
2 
3throw_unless(
4Auth::user()->isAdmin(),
5AuthorizationException::class,
6'You are not allowed to access this page'
7);

today()

Thetoday function creates a newIlluminate\Support\Carbon instance for the current date:

1$today=today();

trait_uses_recursive()

Thetrait_uses_recursive function returns all traits used by a trait:

1$traits=trait_uses_recursive(\Illuminate\Notifications\Notifiable::class);

transform()

Thetransform function executes aClosure on a given value if the value is notblank and returns the result of theClosure:

1$callback=function($value) {
2return$value*2;
3};
4 
5$result=transform(5,$callback);
6 
7// 10

A default value orClosure may also be passed as the third parameter to the method. This value will be returned if the given value is blank:

1$result=transform(null,$callback,'The value is blank');
2 
3// The value is blank

validator()

Thevalidator function creates a newvalidator instance with the given arguments. You may use it instead of theValidator facade for convenience:

1$validator=validator($data,$rules,$messages);

value()

Thevalue function returns the value it is given. However, if you pass aClosure to the function, theClosure will be executed then its result will be returned:

1$result=value(true);
2 
3// true
4 
5$result=value(function(){
6return false;
7});
8 
9// false

view()

Theview function retrieves aview instance:

1returnview('auth.login');

with()

Thewith function returns the value it is given. If aClosure is passed as the second argument to the function, theClosure will be executed and its result will be returned:

1$callback=function($value) {
2return (is_numeric($value))?$value*2:0;
3};
4 
5$result=with(5,$callback);
6 
7// 10
8 
9$result=with(null,$callback);
10 
11// 0
12 
13$result=with(5, null);
14 
15// 5
