note 113433 added to function.isset

Regarding empty() vs. isset(): An empty array "is set" according to this function. For arrays, at least, the assertion that !empty() is interchangeable with isset() is definitely not true. // This prints "Is set" $test = array(); if (isset($test)) { print "Is set"; } // This does not print anything if (!empty($test)) { print "This won't get printed."; } ---- Server IP: 69.147.83.199 Probable Submitter: 69.54.49.230 ---- Manual Page -- http://php.net/manual/en/function.isset.php Edit -- https://master.php.net/note/edit/113433 Del: integrated -- https://master.php.net/note/delete/113433/integrated Del: useless -- https://master.php.net/note/delete/113433/useless Del: bad code -- https://master.php.net/note/delete/113433/bad+code Del: spam -- https://master.php.net/note/delete/113433/spam Del: non-english -- https://master.php.net/note/delete/113433/non-english Del: in docs -- https://master.php.net/note/delete/113433/in+docs Del: other reasons-- https://master.php.net/note/delete/113433 Reject -- https://master.php.net/note/reject/113433 Search -- https://master.php.net/manage/user-notes.php
