Compare two HTML using PHP

Highly accurate PHP diff checker to compare HTML files and find differences between them

Our powerful PHP SDK allows you to find the difference between HTML documents and save the results to a convenient format for viewing. To verify our product capabilities, compare HTML files using this PHP library and see the differences.

Compare HTML in PHP

Our PHP SDK is designed to give you the most accurate result, even though comparison is a complex function itself.

Sometimes you need to be sure that the document in the HTML format has not been changed, and if it has, you need to find out what the difference is. Just use our PHP diff tool to compare two HTML files and find differences in whole words or single characters. Moreover, if only one character in a word has changed, this word will be marked as changed entirely.

Now you no longer need to spend time manually comparing HTML documents, and you can quickly find even small changes and export such diffs to a document in a convenient format.

Try to compare HTML documents

Check out how our solution to compare HTML files using PHP SDK works. To achieve this, load the HTML files you want to compare and select the export file format – it will be automatically loaded after comparing.

Note that you need to accept all revisions in compared documents before calling the comparison method, as shown in our example:
