PHP client for the checker.html5.org API. Can be configured to use a self-hosted version of the API.
Version >= 2.0.0 requires PHP >= 5.6.
Version <= 1.1.0 supports PHP <= 5.6, but won't be maintained anymore.
<?php
$document = file_get_contents('my-page.html');
$validator = new HtmlValidator\Validator();
$result = $validator->validateDocument($document);
$result->hasErrors(); // true / false
$result->hasWarnings(); // true / false
$result->getErrors(); // array(HtmlValidator\Message)
echo $result; // Prints all messages in human-readable format
echo $result->toHTML(); // Prints all messages HTML-formattedTo include html-validator in your project, add it to your composer.json file:
{
"require": {
"rexxars/html-validator": "^2.1.0"
}
}Document to be validated (validate-me.html):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Invalid HTML4!</title>
</head>
<body>
<p>This document is not a proper, well-formed HTML4 document!</p>
<p>It contains fatal flaws, like:</p>
<ul>
<li><div> tags which are not closed</li>
<li>span-tags which are never opened are attempted closed </span></li>
</ul>
</body>
</html>Using the validator:
<?php
$document = file_get_contents('validate-me.html');
$validator = new HtmlValidator\Validator();
$validator->setParser(HtmlValidator\Validator::PARSER_HTML4);
$result = $validator->validateDocument($document);
echo $result;Output:
info: HTML4-specific tokenization errors are enabled.
error: End tag “li” seen, but there were open elements.
From line 10, column 44; to line 10, column 48
not closed</li>
error: Unclosed element “div”.
From line 10, column 13; to line 10, column 17
<li><div> tags
error: Stray end tag “span”.
From line 11, column 67; to line 11, column 73
ed closed </span></li>
Since 1.1.0 you can validate URLs as well:
<?php
$validator = new HtmlValidator\Validator();
$validator->setParser(HtmlValidator\Validator::PARSER_HTML5);
$result = $validator->validateUrl($url);
echo $result;Note that if you want to check pages that return status codes that are not in the 2xx-range (like a 404-page), you need to pass a checkErrorPages option:
$validator = new HtmlValidator\Validator();
$validator->setParser(HtmlValidator\Validator::PARSER_HTML5);
$result = $validator->validateUrl($url, ['checkErrorPages' => true]);
echo $result;Check out validator.nu for instructions on setting up the service. Once set up, you can configure the validator to use a different host:
<?php
$validator = new HtmlValidator\Validator('http://self-hosted-validator.domain.com');MIT licensed. See LICENSE for full terms.
