note 124642 added to function.list

Setting it like <?php list($var1,$varN) = null ?> does _not_ raise an E_NOTICE (or other error) and afaics effectively equals an https://php.net/function.unset of $var1,$varN. I note this as contrasting with the fact that PHP triggers an E_NOTICE about "Undefined offset" "if there aren't enough array elements to fill the list()", as attow documented for https://php.net/control-structures.foreach#control-structures.foreach.list and here only noted in https://php.net/function.list#122951 by Mardaneus. For completeness, a bash(1) (v5.0 or 4.3 on macos10.13) cli test producing the same result for all my PHP-versions (installed via macports.org) follows. It's also tested with php7.3 using bash5.0 on Debian10: bash --noprofile --norc -c 'for php in php{{53..56},{70..73}};do for literal in "array()" null;do echo -n $php …=$literal:&&$php -n -d error_reporting=E_ALL -r "var_dump(list(\$var)=$literal);";done;done' # Above produces the same result pairs per version from: php53 …=array(): Notice: Undefined offset: 0 in Command line code on line 1 array(0) { } # ... to: php73 …=null:NULL ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 188.148.206.216) ---- Manual Page -- http://php.net/manual/en/function.list.php Edit -- https://master.php.net/note/edit/124642 Del: integrated -- https://master.php.net/note/delete/124642/integrated Del: useless -- https://master.php.net/note/delete/124642/useless Del: bad code -- https://master.php.net/note/delete/124642/bad+code Del: spam -- https://master.php.net/note/delete/124642/spam Del: non-english -- https://master.php.net/note/delete/124642/non-english Del: in docs -- https://master.php.net/note/delete/124642/in+docs Del: other reasons-- https://master.php.net/note/delete/124642 Reject -- https://master.php.net/note/reject/124642 Search -- https://master.php.net/manage/user-notes.php
