Spam Filter
===========

[](#spam-filter)

The Spam-Filter package defines an object-oriented layer for checking strings about spam.

Build-in Filter Types
---------------------

[](#build-in-filter-types)

### Regex Filter

[](#regex-filter)

The Regex Filter is build to match Spam by an array of Regex patterns. If a regex pattern result matches the input will rate as spam.

### Blacklist Filter

[](#blacklist-filter)

The Blacklist Filter is used to match Spam by an array of patterns. If the input contain a pattern it will rate as spam .

### Whitelist Filter

[](#whitelist-filter)

The Whitelist Filter is build to check if the input contains any whitelisted patterns. If no whitelisted pattern contained the input will rate as spam.

### Url Filter

[](#url-filter)

The URL Filter is build to match if the input contains url's.

### Duplication Filter

[](#duplication-filter)

The Duplication Filter is build to match word duplications in text's. The `$minConsecutiveWords` defines if only words or sentences with a specific length will be matched. Warning: For larger text this filter performs a lot of operations.

Example
-------

[](#example)

```
$spamFilter = new \Flexic\SpamFilter\SpamFilter([
    new \Flexic\SpamFilter\Filter\BlacklistFilter([
        'want to buy'
    ]),
    new \Flexic\SpamFilter\Filter\RegexFilter([
        '/\[\[url\=.*\]\]/'
    ])
]);

$spamFilter->check(
    'Hello, how are you? Do you want to buy [[url=https://example.com/product]] this Product?'
); // Result: true (both filters detected spam)

$spamFilter->check(
    'Hey my friend. Do you want to test a new PHP Library?'
); // Result: false (No filter detected spam)
```

Create custom filter
--------------------

[](#create-custom-filter)

The Spam-Filter supports the creation of custom filters. The Custom-Filters must implement the `\ThemePoint\SpamFilter\Filter\FilterInterface` with it's defined functions.

Example:

```
class EmailFilter implements \Flexic\SpamFilter\Filter\FilterInterface
{
    public function check($input): bool
    {
        \preg_match_all('/(([^ ].*)@(.*))/', $input, $matches, \PREG_SET_ORDER, 0);

        if (\count($matches) > 0) {
            return true;
        }

        return false;
    }
}
```

Pay attention to the following behavior of the `check` function:

- Return `true` if spam is detected in input.
- Return `false` if no spam is detected in input.

Exceptions
----------

[](#exceptions)

You can control how the Spam Filter react if an exception is thrown. The value of `$responseOnException` is equivalent to the filter results.

If you want that the Spam Filter defines an input as Spam if an exception is thrown set this value to `true`.
