Laravel includes a variety of global "helper" PHP functions. Many of these functions are used by the framework itself; however, you are free to use them in your own applications if you find them convenient.

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 3throw_if(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// true4 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,$callback);10 11// 012 13$result=with(5, null);14 15// 5
