||||
| 4 | * JavaScript-like HTML DOM Element. |
||||
| 5 | * |
||||
| 6 | * This class extends PHP's DOMElement to allow |
||||
| 7 | * users to get and set the innerHTML property of |
||||
| 8 | * HTML elements in the same way it's done in |
||||
| 9 | * JavaScript. |
||||
| 10 | * |
||||
| 11 | * Example usage: |
||||
| 12 | * |
||||
| 13 | * ```php |
||||
| 14 | * require_once 'JSLikeHTMLElement.php'; |
||||
| 15 | * header('Content-Type: text/plain'); |
||||
| 16 | * $doc = new DOMDocument(); |
||||
| 17 | * $doc->registerNodeClass('DOMElement', 'JSLikeHTMLElement'); |
||||
| 18 | * $doc->loadHTML('<div><p>Para 1</p><p>Para 2</p></div>'); |
||||
| 19 | * $elem = $doc->getElementsByTagName('div')->item(0); |
||||
| 20 | * |
||||
| 21 | * // print innerHTML |
||||
| 22 | * echo $elem->innerHTML; // prints '<p>Para 1</p><p>Para 2</p>' |
||||
| 23 | * echo "\n\n"; |
||||
| 24 | * |
||||
| 25 | * // set innerHTML |
||||
| 26 | * $elem->innerHTML = '<a href="http://fivefilters.org">FiveFilters.org</a>'; |
||||
| 27 | * echo $elem->innerHTML; // prints '<a href="http://fivefilters.org">FiveFilters.org</a>' |
||||
| 28 | * echo "\n\n"; |
||||
| 29 | * |
||||
| 30 | * // print document (with our changes) |
||||
| 31 | * echo $doc->saveXML(); |
||||
| 32 | * ``` |

Are you sure
$value of type array|string can be used in concatenation?

If this is a false-positive, you can also ignore this issue in your code via the

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.
This is most likely a typographical error or the method has been renamed.
