Short Description Wikidiff2 is a PHP extension which formats changes between two input texts, producing HTML or JSON.
License GPL-2.0-or-later
FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package wikidiff2
wikidiff2
Wikidiff2 is a PHP extension which formats changes between two input texts, producing HTML or JSON.
It performs word-level diffs, including support for Thai word segmentation. It can detect moved and split lines.
Dependencies
- GCC 4.7+
libthai, a Thai language support library http://linux.thai.net/plone/TLWG/libthai/. On Debian-based systems this also needs thelibthai0andlibthai-devpackages.
To build wikidiff2 as a PHP extension, you also need the php-dev and pkg-config packages.
Compilation and installation
License
wikidiff2 is licensed under the GPL v2 or any later version.
Historically the PHP License was incompatible with the GPL, meaning that binaries were not redistributable. However that was resolved in 2026 with version 4 of the PHP License, which is merely the BSD-3-Clause license and explicitly GPL compatible.
See COPYING and https://www.php.net/license/ for more details.
Configuration
The following php.ini settings are supported:
wikidiff2.moved_line_threshold
Wikidiff2 estimates similarity of added and deleted lines based on changed character count. When the similarity of an added and deleted line is greater than this threshold, the lines are displayed as moved.
Range 0.0 .. 1.0. Default 0.4.
wikidiff2.change_threshold
Changed lines with a similarity value below this threshold will be split into a deleted line and added line. This helps matching up moved lines in some cases.
Range 0.0 .. 1.0. Default 0.2.
wikidiff2.moved_paragraph_detection_cutoff
When the number of added and deleted lines in a table diff is greater than this limit, no attempt to detect moved lines will be made.
Default 100.
wikidiff2.max_word_level_diff_complexity
When comparing two lines for changes within the line, a word-level diff will be done unless the product of the LHS word count and the RHS word count exceeds this limit.
Default 40000000.
Usage
The input is assumed to be UTF-8 encoded. Invalid UTF-8 may cause undesirable operation, such as truncation of the output, so the input should be validated by the application. The input text should have UNIX-style line endings.
wikidiff2_do_diff
Compare two strings $text1 and $text2, and produce output formatted as a fragment of an HTML
table, that is, a series of <tr> elements.
$numContextLines is the number of copied context lines shown before and after each change. Before each block of context lines and changes, a line number will appear as an HTML comment inside a tr/td, e.g.
This allows the application to localize line numbers.
wikidiff2_inline_diff
Compare two strings $text1 and $text2, and produce output formatted as inline HTML.
wikidiff2_inline_json_diff
Compare two strings $text1 and $text2 and produce output formatted as JSON.
See the JSON diff format documentation.
wikidiff2_multi_format_diff
Compare two strings $text1 and $text2 with an associative array of options:
-
numContextLines: The number of context lines shown before and after each block
-
changeThreshold: The minimum similarity a pair of lines must have to be detected as a change and shown as a word-level diff. If present, this overrides php.ini
wikidiff2.change_threshold. -
movedLineThreshold: The minimum similarity a pair of lines must have to be detected as a moved line. If present, this overrides php.ini
wikidiff2.moved_line_threshold. -
maxMovedLines: The maximum number of added or deleted lines, above which no move detection will be performed. If present, this overrides php.ini
moved_paragraph_detection_cutoff. -
maxWordLevelDiffComplexity: The maximum complexity of a word-level diff. If the product of the word count in the LHS and RHS exceeds this value, a word-level diff will not be done. If present, this overrides php.ini
wikidiff2.max_word_level_diff_complexity. -
maxSplitSize: The maximum number of lines in
$text2which may be considered for a word-level diff against a single line of$text1. Default: 1. -
initialSplitThreshold: The minimum similarity which must be maintained during a split detection search. The search terminates when the similarity falls below this level. Default: 0.1.
-
finalSplitThreshold: The minimum similarity which must be achieved in order to display the comparison between one line and several lines as a split. Default 0.6.
- formats: An array of desired formats. Each format is one of the following strings:
table,inlineorinlineJSON. The default is['table'].
The return value is an associative array of formatted outputs. The key of each element is the
format name table, inline or inlineJSON, and the value is a string.
wikidiff2_version
Produces the same thing as phpversion('wikidiff2'). Probably should be deprecated.
