note 114811 added to reserved.variables.environment

Please note that writing to $_ENV does not actually set an environment variable, i.e. the variable will not propagate to any child processes you launch (except forked script processes, in which case it's just a variable in the script's memory). To set real environment variables, you must use putenv(). Basically, setting a variable in $_ENV does not have any meaning besides setting or overriding a script-wide global variable. Thus, one should never modify $_ENV except for testing purposes (and then be careful to use putenv() too, if appropriate). PHP will not trigger any kind of error or notice when writing to $_ENV. ---- Server IP: 195.54.192.44 Probable Submitter: 109.167.130.165 ---- Manual Page -- http://php.net/manual/en/reserved.variables.environment.php Edit -- https://master.php.net/note/edit/114811 Del: integrated -- https://master.php.net/note/delete/114811/integrated Del: useless -- https://master.php.net/note/delete/114811/useless Del: bad code -- https://master.php.net/note/delete/114811/bad+code Del: spam -- https://master.php.net/note/delete/114811/spam Del: non-english -- https://master.php.net/note/delete/114811/non-english Del: in docs -- https://master.php.net/note/delete/114811/in+docs Del: other reasons-- https://master.php.net/note/delete/114811 Reject -- https://master.php.net/note/reject/114811 Search -- https://master.php.net/manage/user-notes.php
