Source-derived summary

Yii is an open source, object-oriented, component-based MVC PHP web application framework. Yii is pronounced as "Yee" or [ji:] and in Chinese it means "simple and evolutionary" and it can be an acronym for "Yes It Is!".

History

Yii started as an attempt to fix perceived drawbacks of the PRADO framework: Slow handling of complex pages, steep learning curve and difficulty to customize many controls. In October 2006, after ten months of development, the first alpha version of Yii was released, followed by the formal 1.00 release in December 2008.

Yii 1.1 was released in January 2010 adding a form builder, relational Active record queries, a unit testing framework and more. The Yii community continues to follow the 1.1 branch with PHP7+ support and security fixes. The latest version 1.1.23 was released in December 2020.

In May 2011 the developers decided to use new PHP versions and fix architectural shortcomings, resulting in version 2.0. In May 2013 the Yii 2.0 code went public, followed by the first stable release in October 2014. PHP8 is supported since version 2.0.38.

Editorial summary

This brief starts where responsible research should: with the source description of “Yii” as web application framework. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2006, 2008, 2010, 2020—that can be checked directly. The authority record carries competing date values—2008-01-01, 2008-12-03—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where application and framework can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as web application framework. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 1, 2026. The linked authority identifier is Q1466168. 1 of 4 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 2006, 2008, 2010 and 2020.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
