Support the following **input data** types: **string, integer, float, boolean, null and object** (must have a \_\_toString method) Support the following **output data** types: string, **int, float, bool and stringOrNull, intOrNull, floatOrNull**

Installation
------------

[](#installation)

Install in your projects:

```
composer require php-filter/string
```

And use:

```
$filter = Filter::of('/_big_ball_of_mud_/')
            ->replace('/', '')
            ->replace('_', '')
            ->upperWords();

$filter->valueString(); // 'Big Ball Of Mud'

```

**Filter list:**

For a list of filters and more examples of their application, see [unit tests](https://github.com/php-filter/string-filter/tree/main/tests/Filters).

```
$filter = Filter::of('/_big_ball_of_mud_/')
            ->replace('/', '')
            ->replace('_', '')
            ->upperWords();

$filter->valueString(); // 'Big Ball Of Mud'
```

**An example of a reusable filter grouping:**

```
$groupFilters = function ($value) {
	return Filter::of($value)->trim()->upperFirst()->append('.');
};

$filter = $groupFilters(' wikipedia is a free online encyclopedia');

$filter->valueString(); // 'Wikipedia is a free online encyclopedia.'
```

**Example value output:**

```
$filter = Filter::of(10.00)->value()->int() // 10
$filter = Filter::of(10.00)->value()->string() // '10.00'
$filter = Filter::of(true)->value()->string() // 'true'
$filter = Filter::of(null)->value()->intOrNull() // null
```

**Example of value information:**

```
$info = Filter::of('wikipedia is a free online encyclopedia, created and edited by by volunteers')->info();

$info->length(); // 76
$info->wordsCount(); // 12
$info->phaseCount('ee'); // 2
```
