note 111351 added to function.array-merge

CAUTION: "numeric" in the description means something different than is_numeric() or gettype(). It includes strings containing all digits! "numeric" keys append: <?php assert(array(0=>0,1=>1) === array_merge(array(9=>0), array(9=>1))); assert(array(0=>0,1=>1) === array_merge(array('9'=>0), array('9'=>1))); ?> non-"numeric" keys overwrite: <?php assert(array('z'=>1) === array_merge(array('z'=>0), array('z'=>1))); ?> Both bishop and nzujev point this out, but I thought it bore special emphasis. ---- Server IP: 69.147.83.199 Probable Submitter: 70.16.195.218 ---- Manual Page -- http://php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/111351 Del: integrated -- https://master.php.net/note/delete/111351/integrated Del: useless -- https://master.php.net/note/delete/111351/useless Del: bad code -- https://master.php.net/note/delete/111351/bad+code Del: spam -- https://master.php.net/note/delete/111351/spam Del: non-english -- https://master.php.net/note/delete/111351/non-english Del: in docs -- https://master.php.net/note/delete/111351/in+docs Del: other reasons-- https://master.php.net/note/delete/111351 Reject -- https://master.php.net/note/reject/111351 Search -- https://master.php.net/manage/user-notes.php
