This little package tests a string against a disallowlist.

If you are looking for a Laravel-specific implementation, see

The `isDisallowed()` method can use wildcards, like \*.

Under the hood, `accentinteractive/disallowtester` uses `fnmatch()`, so you can use the same wildcards as in that php function (the globbing wildcard patterns):

- `*sex*` disallows **sex**, **sex**uality and bi**sex**ual.
- `cycle*` disallows cycle and cycles, but not bicycle.
- `m[o,u]m` disallows mom and mum, but allows mam.
- `m?n` disallows man and men, but allows moon.

Usage
-----

[](#usage)

### Setting the disallowlist

[](#setting-the-disallowlist)

You can pass the disallowlist in the constructor or via other methods.

```
// Pass the disallowlist in the constructor
$disallowLister = new DisallowLister(['foo']); // ['foo']

// Set the disallowlist in the setter method
$disallowLister->setDisallowList(['bar']); // ['bar']

// Add an item to the disallowlist
$disallowLister->add('baz'); // ['bar', 'baz']

// Add multiple items to the disallowlist
$disallowLister->add(['bat', 'fiz']); // ['bar', 'baz', 'bat', 'fiz']

// Remove an item from the disallowlist
$disallowLister->remove('fiz'); // ['bar', 'baz', 'bat']

// Remove multiple items from the disallowlist
$disallowLister->remove(['baz', 'bat']); // ['bar']
```

### Checking data against the disallowlist

[](#checking-data-against-the-disallowlist)

```
## Literal string
$disallowLister = new DisallowLister(['bar', 'foo']);

$disallowLister->isDisallowed('bar'); // Returns true
$disallowLister->isDisallowed('bars'); // Returns false

## Wildcards
// Under the hood, `accentinteractive/disallowtester`
// uses `fnmatch()`, so you can use the same
// wildcards as in that php function (the
// globbing wildcard patterns):
(new DisallowLister(['b?r']))->isDisallowed('bar'); // Returns true
(new DisallowLister(['m[o,u]m']))->isDisallowed('mom'); // Returns true
(new DisallowLister(['*bar*']))->isDisallowed('I like crowbars'); // Returns true
```

### Case sensitivity

[](#case-sensitivity)

```
// By default, matching is not case sensitive
(new DisallowLister(['bar']))->isDisallowed('BAR'); // Returns true

// To set case sensitive matching
(new DisallowLister(['bar']))->caseSensitive(true)->isDisallowed('BAR'); // Returns false
```

### Whole word checking

[](#whole-word-checking)

```
// By default the entire string is checked.
(new DisallowLister())->setDisallowList(['bar'])->isDisallowed('My favorite bar'); // Returns false

// Check word for word.
(new DisallowLister())->setDisallowList(['bar'])->setWordForWord(true)->isDisallowed('My favorite bar'); // Returns true
```

### Testing

[](#testing)

```
composer test
```
