README
This package contains a helper function (and a Facade should you prefer that) called blink
that can cache values. The cache only spans the length of a single request.
blink()->put('key', 'value'); blink()->get('key'); // Returns 'value' blink()->get('prefix*'); // Returns an array of values whose keys start with 'prefix' // once will only execute the given callable if the given key didn't exist yet $expensiveFunction = function() { return rand(); }); blink()->once('random', $expensiveFunction); // returns random number blink()->once('random', $expensiveFunction); // returns the same number blink()->has('key'); // Returns true blink()->has('prefix*'); // Returns true if the blink contains a key that starts with 'prefix' // Specify a default value for when the specified key does not exist blink()->get('non existing key', 'default') // Returns 'default' blink()->put('anotherKey', 'anotherValue'); // Put multiple items in one go blink()->put(['ringo' => 'drums', 'paul' => 'bass']); blink()->all(); // Returns an array with all items blink()->forget('key'); // Removes the item blink()->forget('prefix*'); // Forget all items of which the key starts with 'prefix' blink()->flush(); // Empty the entire blink blink()->flushStartingWith('somekey'); // Remove all items whose keys start with "somekey" blink()->increment('number'); // blink()->get('number') will return 1 blink()->increment('number'); // blink()->get('number') will return 2 blink()->increment('number', 3); // blink()->get('number') will return 5 // Blink implements ArrayAccess blink()['key'] = 'value'; blink()['key']; // Returns 'value' isset(blink()['key']); // Returns true unset(blink()['key']); // Equivalent to removing the value // Blink implements Countable count(blink()); // Returns 0 blink()->put('key', 'value'); count(blink()); // Returns 1
Support us
We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.
We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.
Installation
You can install the package via composer:
composer require spatie/laravel-blink
To enable the package, register the service provider, and optionally register the facade:
// config/app.php 'providers' => [ // ... Spatie\LaravelBlink\BlinkServiceProvider::class, ], 'aliases' => [ ... 'Blink' => Spatie\LaravelBlink\BlinkFacade::class, ],
Usage
A Blink
instance can just be newed up.
$blink = new \Spatie\Blink\Blink()
You can call the following methods on it:
put
/** * Put a value in the blink cache. * * @param string|array $name * @param string|int|null $value * * @return $this */ public function put($name, $value = null)
get
/** * Get a value from the blink cache. * * This function has support for the '*' wildcard. * * @param string $name * * @return null|string */ public function get(string $name)
has
/* * Determine if the blink cache has a value for the given name. * * This function has support for the '*' wildcard. */ public function has(string $name) : bool
once
/** * Only if the given key is not present in the blink cache the callable will be executed. * * The result of the callable will be stored in the given key and returned. * * @param $key * @param callable $callable * * @return mixed */
You can use this to avoid using static variables to cache stuff.
This piece of code
function foo() { static $result = null; if (is_null($result) { $result = ...// do some expensive stuff here } return $result; }
can be rewritten to
function foo() { return blink()->once('fooCache', function() { return ... // do some expensive stuff here }); }
all
/* * Get all values in the blink cache. */ public function all() : array
allStartingWith
/** * Get all values from the blink cache which keys start with the given string. * * @param string $startingWith * * @return array */ public function allStartingWith(string $startingWith = '') : array
forget
/** * Forget a value from the blink cache. * * This function has support for the '*' wildcard. * * @param string $key * * @return $this */ public function forget(string $key)
flush
/** * Flush all values from the blink cache. * * @return $this */ public function flush()
flushStartingWith
/** * Flush all values from the blink cache which keys start with the specified value. * * @param string $startingWith * * @return $this */ public function flushStartingWith(string $startingWith)
pull
/** * Get and forget a value from the blink cache. * * This function has support for the '*' wildcard. * * @param string $name * * @return null|string */ public function pull(string $name)
increment
/** * Increment a value from the blink cache. * * @param string $name * @param int $by * * @return int|null|string */ public function increment(string $name, int $by = 1)
decrement
/** * Decrement a value from the blink cache. * * @param string $name * @param int $by * * @return int|null|string */ public function decrement(string $name, int $by = 1)
