You may pass a closure to the doesntContain method to determine if an element does not exist in the collection matching a given truth test: Alternatively, you may pass a string to the doesntContain method to determine whether the collection does not contain a given item value: You may also pass a key / value pair to the doesntContain method, which will determine if the given pair does not exist in the collection: The doesntContain method uses "loose" comparisons when checking item values, meaning a string with an integer value will be considered equal to an integer of the same value. whenNotEmpty ['name' => 'Galaxy Gear', 'brand' => 'Samsung', 'type' => 'watch']. merge The Str::replace method replaces a given string within the string: The Str::replaceArray method replaces a given value in the string sequentially using an array: The Str::replaceFirst method replaces the first occurrence of a given value in a string: The Str::replaceLast method replaces the last occurrence of a given value in a string: The Str::reverse method reverses the given string: The Str::singular method converts a string to its singular form.

Str::isUlid we can easily use with laravel 5, laravel 6, laravel 7, laravel 8 and laravel 9 application. hasAny Arr::whereNotNull csrf_field Collections contain useful methods that make them very powerful and helpful to use. If a string key in the given items matches a string key in the original collection, then the values for these keys are merged together into an array, and this is done recursively: The min method returns the minimum value of a given key: The mode method returns the mode value of a given key: The nth method creates a new collection consisting of every n-th element: You may optionally pass a starting offset as the second argument: The only method returns the items in the collection with the specified keys: For the inverse of only, see the except method. Str::kebab 'prod-100' => ['product_id' => 'prod-100', 'name' => 'Desk']. Str::studly max transform Arr::divide 'PROD-100' => ['product_id' => 'prod-100', 'name' => 'Desk']. duplicates firstWhere is The Arr::except method removes the given key / value pairs from an array: use Illuminate\Support\Arr; $array = ['name' => 'Desk', 'price' => 100]; $filtered = Arr::except($array, ['price']); // ['name' => 'Desk'] Arr::exists () The Arr::exists method checks that the given key exists in the provided array: use Illuminate\Support\Arr; This value will be returned if the given value is blank: The validator function creates a new validator instance with the given arguments. [['A', 'A'], ['B', 'B'], ['C', 'C', 'C'], ['D']], ['one' => 10, 'three' => 30, 'five' => 50]. This code will split all the relation and convert it into a nested array. flatten Use the whereStrict method to filter using "strict" comparisons. Additional URL segments may be passed in the function's second argument: The to_route function generates a redirect HTTP response for a given named route: If necessary, you may pass the HTTP status code that should be assigned to the redirect and any additional response headers as the third and fourth arguments to the to_route method: The url function generates a fully qualified URL to the given path: If no path is provided, an Illuminate\Routing\UrlGenerator instance is returned: The abort function throws an HTTP exception which will be rendered by the exception handler: You may also provide the exception's message and custom HTTP response headers that should be sent to the browser: The abort_if function throws an HTTP exception if a given boolean expression evaluates to true: Like the abort method, you may also provide the exception's response text as the third argument and an array of custom response headers as the fourth argument to the function. nth We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. excerpt Assuming we wanted to retrieve all people whose age was 26 we could use the whereIn method like so: After the above code has executed, the $results variable will contain a value similar to the following output: To see the effects of the $strict argument, we can change the above example only slightly to cause the method to return no results: Because the age of each person in the $people array is an integer and the item in the $values array in the previous code example is a string, the $results variable would be an empty Collection instance. Step 1: Install Laravel. Arr::query skipUntil The callback should return the value you wish to key the group by: Multiple grouping criteria may be passed as an array.
