note 126941 added to function.explode

Note that an empty input string will still result in one element in the output array. This is something to remember when you are processing unknown input. For example, maybe you are splitting part of a URI by forward slashes (like "articles/42/show" => ["articles", "42", "show"]). And maybe you expect that an empty URI will result in an empty array ("" => []). Instead, it will contain one element, with an empty string: <?php $uri = ''; $parts = explode('/', $uri)); var_dump($parts); ?> Will output: array(1) { [0]=> string(0) "" } And not: array(0) { } ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 82.73.20.120) ---- Manual Page -- https://php.net/manual/en/function.explode.php Edit -- https://main.php.net/note/edit/126941 Del: integrated -- https://main.php.net/note/delete/126941/integrated Del: useless -- https://main.php.net/note/delete/126941/useless Del: bad code -- https://main.php.net/note/delete/126941/bad+code Del: spam -- https://main.php.net/note/delete/126941/spam Del: non-english -- https://main.php.net/note/delete/126941/non-english Del: in docs -- https://main.php.net/note/delete/126941/in+docs Del: other reasons-- https://main.php.net/note/delete/126941 Reject -- https://main.php.net/note/reject/126941 Search -- https://main.php.net/manage/user-notes.php
