v2026.1.22

Marketplace version: 2026.1.92200

Features and Improvements

• Added the InvalidStringOffset diagnostic for string offsets PHP 8 rejects at runtime.

Bug Fixes

• Fixed reading an element of a PHPDoc collection or of a class-based ArrayAccess/collection receiver inferring mixed.
• Fixed reading a character from a string inferring mixed, and an offset write widening a non-array receiver — a string, an int, or an ArrayAccess object — into an array.
• Fixed @implements/@extends/@use losing every type argument when the argument list was written with a space after the comma.
• Fixed a value-of<...> docblock being discarded on a property with a native array declaration.
• Fixed false PropertyTypeMismatch diagnostics for an associative array literal whose field value the engine cannot type, and for an assigned type that is a supertype of the property's declared type.
• Fixed false UndefinedClass diagnostics for a use-site variance projection on a generic type argument.
• Fixed the formatter collapsing the alternative conditions of a multi-line match arm onto the => line.
• Fixed double-clicking a PHP variable selecting only the name, without the leading $.
