README

Starting with PHP 8.1, the filter type FILTER_SANITIZE_STRING was deprecated. To avoid deprecated errors, this class implements similar behavior as the FILTER_SANITIZE_STRING filter. This is done by changing filters using \DealNews\Filter\Filter::FILTER_SANITIZE_STRING to use FILTER_CALLBACK to a closure implementing behavior similar to what \FILTER_SANITIZE_STRING provides.

This class is a drop in replacement for filter_var, filter_var_array, filter_input, and filter_input_array. The only filter that is is modified are ones using \DealNews\Filter\Filter::FILTER_SANITIZE_STRING.

Example

PHP <= 8.0

This is how you used FILTER_SANITIZE_STRING in PHP <=8.0.

<?php

$input = filter_input_array(
    INPUT_GET,
    [
        'id' => FILTER_VALIDATE_INT,
        'search' => FILTER_SANITIZE_STRING
    ]
);

PHP >=8.1

In PHP 8.1 or higher, you can use DealNews\Filter instead like so.

<?php

use DealNews\Filter\Filter;

$filter = new Filter();

$input = $filter->inputArray(
    INPUT_GET,
    [
        'id' => FILTER_VALIDATE_INT,
        'search' => Filter::FILTER_SANITIZE_STRING
    ]
);
