Installation

composer require digiaonline/common-sanitization-stages

Usage

Let's say you're importing some legacy data into a new system. The original data is user generated content, so it cannot be trusted. Additionally, it contains some simple HTML that you want to strip. On top of all this, the legacy data must be possible to store in a CSV file, so you need to encode it somehow so the CSV delimiter is guaranteed not to occur in the text value.

To accomplish this, just combine the stages you need into a pipeline, then run the pipeline against your data:

<?php

require_once(__DIR__.'/vendor/autoload.php');

$rawInputData = <<<EOT
  The quick brown fox<br />
jumped over the <i>incredibly lazy dog</i> &amp; it
ran away.

EOT;

$encodedInputData = \base64_encode($rawInputData);

/** @var \League\Pipeline\Pipeline $pipeline */
$pipeline = (new \League\Pipeline\Pipeline())
    ->pipe(new \Digia\Sanitization\Stages\Base64DecodeStage())
    ->pipe(new \Digia\Sanitization\Stages\HtmlPurifierStage())
    ->pipe(new \Digia\Sanitization\Stages\HtmlEntityDecodeStage())
    ->pipe(new \Digia\Sanitization\Stages\StripLineFeedsStage(["\n"], true))
    ->pipe(new \Digia\Sanitization\Stages\TrimStringStage());

$outputData = $pipeline->process($encodedInputData);

var_dump($outputData); // string(70) "The quick brown fox jumped over the incredibly lazy dog & it ran away."
