MIT Open Source license applies. Introduction ------------ [](#introduction) Class of stable sort utility methods and standalone functions. Equal values remain in the original order. Only different values are sorted. These sort utility methods follow the same interface and have the same functionality and features as the builtin sort utility methods (except they add guaranteed sort order). Static methods -------------- [](#static-methods) - `bool StableSort::arsort ( array &$array [, int $sort_flags = SORT_REGULAR ] )` - `bool StableSort::asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )` - `bool StableSort::natcasesort ( array &Sarray )` - `bool StableSort::natsort ( array &Sarray )` - `bool StableSort::uasort ( array &$array , callable $value_compare_func )` - `bool StableSort::uksort ( array &$array , callable $value_compare_func )` - `bool StableSort::usort ( array &$array , callable $value_compare_func )` For backwards compatibility, functions (prefixed with `s`) are available that utilize the utility class. Tests ----- [](#tests) PHPUnitTest testcases are included (group `stablesort`) in the `tests`directory. Disclaimers ----------- [](#disclaimers) Only methods that make sense for stable sorting are included, so no `sort` or `ksort` variants. If you can demonstrate the case for any missing function, please let me know and they will be included. These are not the fastest possible implementations. In fact, I guarantee they are not. Performance has been sacrificed for compatibility with their builtin counterparts. Changes ------- [](#changes) ### 2.0.6 [](#206) - PHP 8 sorts stable by default. Use native methods if PHP 8 or more recent. ### 2.0.1 [](#201) - Merge @joelpittet 2.0.0 into main branch, cleaning Drupal specifics. ### 2.0.0 [](#200) - Converted to Utility class. By @joelpittet ### 1.0.3 [](#103) - Added `reset` calls to `sasort`/`sarsort` to ensure pointer. By @emilv. ### 1.0.2 [](#102) - PHP 5.3 compatibility changes by @folliked. ### 1.0.1 [](#101) - composer.json added by @thebeline. ### 1.0 [](#10) - Initial public release ### Health Score 42 — FairBetter than 88% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity48 Moderate usage in the ecosystem Community20 Small or concentrated contributor base Maturity64 Established project with proven stability Bus Factor1 Top contributor holds 75% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
