Zend Studio PHP Version Compatibility

IDE support and runtime support are different

A PHP application can execute on a server even when the editor does not understand its syntax, types, attributes, or debugger protocol. Conversely, an editor may parse a language version that the project’s production runtime cannot execute. Zend Studio compatibility must therefore be established for one exact IDE build and one exact feature, not guessed from the application.

Modern PHP is not verified

Zend Studio is discontinued. It should not be assumed to support current PHP releases, Composer behavior, Xdebug 3, or current operating systems. For modern PHP, the accurate table entry is “not verified / not applicable for modern PHP,” not a green check inferred from text editing.

No invented matrix

Historical point-release mappings were not sufficiently verified from stable official archives for this seed. A cell for PHP 5.x, PHP 7.x, or PHP 8.x could refer to parser syntax, code completion, local interpreter, remote execution, or debugger support; collapsing those into one claim would mislead readers.

How to assess a frozen project

Identify the exact Zend Studio build, project PHP executable, composer.lock constraints, syntax in source, and debugger extension. Test only in an isolated copy. For active work, open the project in a maintained IDE, configure the real runtime separately, and use automated tests to guide modernization.

Verification and maintenance

Zend Studio PHP Version Compatibility was reviewed for this seed on 2026-08-09. Before adopting its recommendations, confirm current releases, platform support, licensing, extension publishers, and configuration syntax through PHP Supported Versions at the official source linked below. Product status and plugin compatibility can change independently of this editorial record.

Test changes on a representative repository and keep Composer scripts, automated tests, static analysis, and version control authoritative. If official documentation no longer supports a claim made on /zend-studio/php-version-compatibility/, mark the fact unknown or update it from a primary source rather than filling the gap from an old tutorial or download mirror.
