note 72556 added to function.array-merge

An earlier comment mentioned that array_splice is faster than array_merge for inserting values. This may be the case, but if your goal is instead to reindex a numeric array, array_values() is the function of choice. Performing the following functions in a 100,000-iteration loop gave me the following times: ($b is a 3-element array) array_splice($b, count($b)) => 0.410652 $b = array_splice($b, 0) => 0.272513 array_splice($b, 3) => 0.26529 $b = array_merge($b) => 0.233582 $b = array_values($b) => 0.151298 ---- Server IP: 69.147.83.197 Probable Submitter: 75.19.79.5 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/72556 Del: integrated -- https://master.php.net/note/delete/72556/integrated Del: useless -- https://master.php.net/note/delete/72556/useless Del: bad code -- https://master.php.net/note/delete/72556/bad+code Del: spam -- https://master.php.net/note/delete/72556/spam Del: non-english -- https://master.php.net/note/delete/72556/non-english Del: in docs -- https://master.php.net/note/delete/72556/in+docs Del: other reasons-- https://master.php.net/note/delete/72556 Reject -- https://master.php.net/note/reject/72556 Search -- https://master.php.net/manage/user-notes.php
