Maintained by [OpenStatSpec](https://github.com/OpenStatSpec). This project continues the MIT-licensed [`tiamo/spss`](https://github.com/tiamo/spss) codebase created by Vladyslav Korniienko. The stable PHP namespace remains `SPSS\` for compatibility. Requirements ------------ [](#requirements) - PHP 8.4.1 or newer - mbstring extension - bcmath extension - zlib extension Installation ------------ [](#installation) ``` composer require openstatspec/spss-sav ``` Usage ----- [](#usage) Read a file into the v3 typed dataset model: ``` use SPSS\Sav\Reader; $dataset = Reader::fromFile('/path/to/input.sav')->readDataset(); foreach ($dataset->rows() as $row) { // Values follow the order of $dataset->variables(). } ``` Write a typed dataset: ``` use SPSS\Sav\Writer; $writer = new Writer($dataset); $writer->save('/path/to/output.sav'); $writer->close(); ``` Numeric `null` cells represent SPSS system-missing values. Strings must always be strings; an empty string is an ordinary value. SPSS dates, times, and currencies remain numeric values whose presentation is described by `VariableFormat`. See the [v3 typed Dataset guide](./docs/index.md) for creating datasets, metadata, SAV/ZSAV support, and migration from the legacy array API. The older low-level [examples](./examples) remain available during migration. Changelog --------- [](#changelog) Please have a look in [CHANGELOG](CHANGELOG.md) Development ----------- [](#development) Install the locked development dependencies: ``` composer install ``` The install command activates the versioned pre-push hook in `.githooks`. It runs the same complete QA suite used in CI before every push. You can also run the checks directly: ``` composer qa composer qa:release ``` `composer qa` validates and audits Composer dependencies, lints PHP syntax, checks coding style, runs Rector in dry-run mode, performs PHPStan level 6 analysis with strict rules, and executes the PHPUnit 13 tests. `composer qa:release` additionally enforces: - at least 85% executable-line coverage; - at least 74% branch coverage across the deterministic branch shards; - Infection's mutation-testing threshold, with timeouts counted against the score and capped; - bidirectional SAV/ZSAV interoperability with R/haven. The release suite requires Xdebug coverage plus `Rscript` with the `haven` package. The pre-push hook runs this complete release suite. Run `composer fix` to apply safe Rector and coding-style fixes. See [Quality and release gates](./docs/quality-gates.md) for individual commands, report locations, and the rationale for each threshold.
