PHPStan 0.11 has been made possible by LOVOO:

LOVOO: PHPStan is an elementary part of our development workflow. We cannot live without it! Thanks for the great work!

Also, my work on PHPStan is enabled by generous patrons over at Patreon. If PHPStan makes your life easier, consider a contribution, it'll be greatly appreciated!

Major new features

• Ability to ignore errors by path (#1411, #1619), thanks josephzidell, damnedest!
• Check - reporting unreachable conditions on level 4. Previously, only projects with checkAlwaysTrue* flags set to true (usually with installed strict-rules) found out about always true conditions. With this change, always-true conditions with else branches and ternary operators are reported (186e4e0ed845070780b1647703e8eaa001222284, e06af0e69562052c088005e9747c19bc8bfd783a):

if ($alwaysTrue) {
	// ...
} else {
	// dead - reported on level 4!
}

• Improved analysis of non-empty arrays (5716b2e493edb8085ad27e5da3fef1f0920438c8, 21309e233cf02d7dd814f6f12c8553e373d20d61, deb70ef6706c12037cbac1b163cd6652c9ded733) - #336, #165, #1539, #1073, #959, #1505, #1409
• Check (level 3) - validate method signatures against parents and implemented interfaces - forces Liskov substitution principle (#1292), thanks iluuu1994!
• Check - validation of patterns used in preg_* functions on level 0 (#1567), thanks iluuu1994!
• Check (level 2) - string and castable-to-string types in echo and print statements (#1462), thanks dmitrydymarchuk!
• Check (level 3) - report invalid offset assignments (56be6db5fb44b16543e44f4d1b9c62f2c0d9e75b) - e.g. $string['foo'] = 'bar' leads to an error.
• Check (level 2) - invalid comparison between an object and a number (#1582), thanks jasny!
• Check (level 2) - check default function parameter type against typehint and phpDoc (#1608), thanks iluuu1994!
• Loaded extensions for known functions in PHP runtime are no longer needed for successful ananlysis (8e6a215e14f951824fb6686ffd700eb96f892790)

Improvements

• Implicit [**inheritDoc**](https://github.com/inheritDoc) from parent classes and interfaces (#1533), thanks iluuu1994!
• Memory consumption improvement - limit amount of cached files for parser (#1673), thanks damnedest!
• Improved precision of reported lines in some rules (9f7ab5b7713ebf4c6b95542c68221e717a9994de, eaedf17ca7451aa93cd43c989f10847f40dbbfcd, 9a2646d4dd03ca4be64277e53404118cb0df28a3)
• Dead branches are not analysed (295c8f2df2a3eafdd741e8fd3f2807db70757ec4)
• IncompatiblePhpDocTypeRule - detect NeverType in [**param**](https://github.com/param) and [**return**](https://github.com/return) (a0e2a76158d4ecdeb506f7867e9c92eff94b23d8)
• IncompatiblePropertyPhpDocTypeRule - check for ErrorType and NeverType in properties (7e66ceefa9887ffb1d2ead25614a34c8691ad197)
• Report traits in anonymous function typehints - traits are not valid types (2a96f1481862fdc77fd954efe1c51ee4d8296d5b)
• Always have a nice progressbar (6b04dca433d54310cfccfe4ee422c7f105c6d9ee)
• Detect $var[] used in read context (#1309), thanks iluuu1994!
• Improved invalid offset access detection (7a630b8d5353fd80d5d1ef89c1ca1f0d3f79a45a)
• Moved reporting of object accesses and calls to level 6 (216fb2e62d17e1184794e1d021cc590b8a942165)
• Moved partially correct types in an encapsed string to level 6 (0470c530d831118885f3cac2e78581ab816504f1)
• Array from pathinfo may or may not contain extension key (#1637), thanks jasny!
• Make binary operations aware of strings (#1628), thanks wata727!
• Collecting error handler to report multiple parse errors at once (7b38a2301ecc5f1b47142ff89691f12b903c3590)
