- env(): guard non-string values (int argc, array argv in CLI) before strtolower() to prevent TypeError under declare(strict_types=1) - esc(): propagate $encoding in recursive array calls (was ignored before), add early return after array processing, replace single static $escaper with static $escapers[] cache keyed by encoding - tests: data-provider test for env() non-string types, three tests for esc() foreach reference leak

Fix:
env()TypeError in CLI +esc()improvementsWhat
Fixes two bugs in
system/Common.php.env()— In CLI,$_SERVERcontains non-string values (argcisint,argvisarray). Passing them tostrtolower()threw aTypeErrorunderdeclare(strict_types=1). Added anis_string()guard before thematchexpression; non-string values are returned as-is.esc()— Three fixes applied together:foreach ($data as &$value)left a dangling reference after the loop; addedunset($value)to prevent silent mutation of the last array element in the calling scope$encodingwas not propagated in recursive array callsstatic $escaperwithstatic $escapers[]keyed by encoding for correct per-encoding cachingTests
Added a data-provider test for
env()covering non-string$_SERVER/$_ENVvalues (int, array, float), and three tests verifying theesc()reference leak is gone.Files changed
