README

An extension of PHP's DOMDocument library. This library implements many common jQuery functions, adds support for HTML5, CSS selectors, method chaining and performing operations on sets of matched results.

Requirements

• PHP >= 7.0.0
• Composer

Installation

I recommend installing this package via Composer.

composer require perry-rylance/dom-document

Usage

Instantiate DOMDocument and enjoy the jQuery-like functions now at your disposal.

As of version 2.0.0, this library does not add jQuery-like methods to DOMElement, in order to avoid future collisions with the HTML living standard spec. Rather, these jQuery-like methods are implemented on DOMQueryResults in the same manner jQuery objects work.

Read the libraries documentation.

Migrating from 1.0.*

If you are considering switching from 1.0.* to >= 2.0.0 please note there are some considerations to be aware of.

Moved methods

Many, many methods which were previously implemented on DOMElement are now on DOMQueryResults. This helps avoid collisions with PHP's native DOMElement as more convenience methods are added there, like in the recent RFC sprint.

Avoid querySelector

The method querySelector is still implemented and publicly visible for internal reasons, however, I'd recommend avoiding using this method.

Any code which did expect a single DOMElement from querySelector may now create fatal errors.

DOMDocument::querySelector now returns a DOMQueryResults in an effort to make almost all common methods still available and keep old code stable, however, some methods (such as isBefore) are not implemented by DOMQueryResults. These methods are intended for internal use. Documentation will be updated to reflect this.

Static contains

DOMElement::contains is now static, in line with jQuery's design pattern. This may create warnings for users migrating from older versions.

PHP requirement

This library has dropped support for PHP < 7.0.0 in version >= 2.0.0

Enhanced manipulation

Many methods, such as append, prepend, before, after, wrap, and many others, now support passing in an entire array or DOMQueryResults as an argument.

This can be used to append content to multiple elements, where there is more than one element in the set.

If the target set contains only one element, then the same elements passed into these functions will be added to the DOM tree.

If the target set contains multiple elements, then the input elements will be cloned - please note that manipulating the input set after performing these operations may not affect the DOM tree, because the new content is cloned from the input set.
