Laravel Stringable Extras

Adds the missing whenDoesntContain() and whenDoesntContainAll() methods to Laravel's fluent Stringable class.

Laravel ships with whenContains() and whenContainsAll(), and has negative counterparts for start/end (whenDoesntStartWith, whenDoesntEndWith), but the negative counterpart for contains was never added to the framework. This package fills that gap.

Requirements

• PHP 8.2+
• Laravel 11, 12, or 13

Installation

composer require sumaiazaman/laravel-stringable-extras

The service provider is auto-discovered — no manual registration needed.

Usage

whenDoesntContain()

Executes the callback when the string does not contain the given substring. Accepts a string or an array of strings (any match counts).

// Callback fires — string doesn't contain 'xxx'
$result = str('hello world')
    ->whenDoesntContain('xxx', fn ($s) => $s->upper());
// 'HELLO WORLD'

// Callback is skipped — string contains 'world'
$result = str('hello world')
    ->whenDoesntContain('world', fn ($s) => $s->upper());
// 'hello world'

// With a default callback
$result = str('hello world')
    ->whenDoesntContain(
        'world',
        fn ($s) => $s->upper(),
        fn ($s) => $s->title(),
    );
// 'Hello World'

// Array of needles — callback fires only if none are present
$result = str('hello world')
    ->whenDoesntContain(['foo', 'bar'], fn ($s) => $s->upper());
// 'HELLO WORLD'

whenDoesntContainAll()

Executes the callback when the string does not contain all of the given substrings. If even one needle is missing, the callback fires.

// Callback fires — 'xxx' is not in the string
$result = str('hello world')
    ->whenDoesntContainAll(['hello', 'xxx'], fn ($s) => $s->upper());
// 'HELLO WORLD'

// Callback is skipped — both needles are present
$result = str('hello world')
    ->whenDoesntContainAll(['hello', 'world'], fn ($s) => $s->upper());
// 'hello world'
