PHPStan: 0 errors (level max + strict rules) Key improvements: - Replace elvis operator (?:) with explicit null checks - Replace empty() with explicit type-safe comparisons - Add PHPDoc type annotations for better static analysis - Replace == with === for strict comparisons - Add null-safety checks for DOM/XPath operations - Improve type inference for magic properties and dynamic methods - Add PHP 7.4/8.x compatible type handling (resource vs CurlHandle) Modified components: - Core: Embed, Extractor, Document, EmbedCode, etc. (13 files) - HTTP layer: Crawler, CurlClient, CurlDispatcher (5 files) - Detectors: All core detectors (17 files) - Adapters: Archive, Gist, ImageShack, Twitter, Wikipedia, etc. (60 files) -

Changes: - String detectors: Use ($result !== null && $result !== '') check to preserve fallback behavior for empty strings - DateTime/UriInterface detectors: Use ($result !== null) check as these types cannot have empty values - Ensures backward compatibility with master branch behavior - Fixes 15 PHPStan ternary.shortNotAllowed errors - All tests pass without regressions --- src/Adapters/Archive/Detectors/AuthorName.php | 2 +- src/Adapters/Archive/Detectors/Description.php | 2 +- src/Adapters/Archive/Detectors/Title.php | 2 +- src/Adapters/Gist/Detectors/AuthorName.php | 2 +- src/Adapters/ImageShack/Detectors/AuthorName.php | 3 +-- src/Adapters/ImageShack/Detectors/Description.php | 3 +-- src/Adapters/ImageShack/Detectors/Image.php | 1 - src/Adapters/ImageShack/Detectors/PublishedTime.php | 1 - src/Adapters/ImageShack/Detectors/Title.php | 3 +-- src/Adapters/Twitter/Detectors/AuthorName.php | 2 +- src/Adapters/Twitter/Detectors/Description.php | 2 +- src/Adapters/Wikipedia/Detectors/Description.php | 2 +- src/Adapters/Wikipedia/Detectors/Title.php | 2 +- 13 files changed, 11 insertions(+), 16 deletions(-) diff --git a/src/Adapters/Archive/Detectors/AuthorName.php b/src/Adapters/Archive/Detectors/AuthorName.php index a4b4c345..bf59c394 100644 --- a/src/Adapters/Archive/Detectors/AuthorName.php +++ b/src/Adapters/Archive/Detectors/AuthorName.php @@ -15,6 +15,6 @@ public function detect(): ?string $api = $extractor->getApi(); $result = $api->str('metadata', 'creator'); - return $result !== null ?

Now empty and whitespace-only strings are treated as missing data, triggering the fallback chain. Problem: When oembed or other primary sources returned empty strings instead of null, detectors would return those empty values immediately, preventing fallback to metas, linked data, or document sources that might contain valid data. Solution: Add empty string validation using trim() to ensure fallback chain executes properly: if (is_string($result) && trim($result) !== '') Impact: - AuthorName: Empty oembed author_name now falls back to metas - Title: Empty oembed/metas titles now fall back to document - Description: Empty oembed/metas descriptions fall back to linked data - ProviderName: Empty oembed/metas names fall back to hostname - Language: Empty html lang attributes fall back to meta tags This improves metadata extraction quality by utilizing all available sources instead of stopping at the first non-null but empty response. --- src/Detectors/AuthorName.php | 2 +- src/Detectors/Description.php | 4 ++-- src/Detectors/Language.php | 8 ++++---- src/Detectors/ProviderName.php | 4 ++-- src/Detectors/Title.php | 4 ++-- 5 files changed, 11 insertions(+), 11 deletions(-) diff --git a/src/Detectors/AuthorName.php b/src/Detectors/AuthorName.php index bfb9093d..3d1dc67b 100644 --- a/src/Detectors/AuthorName.php +++ b/src/Detectors/AuthorName.php @@ -11,7 +11,7 @@ public function detect(): ?string $metas = $this->extractor->getMetas();
