note 127036 added to function.getenv

Using square brackets to access an array element by index number is not behaving as expected in PHP 7.1.7. I use: $myvar=getenv(); to get an array of all the environment variables, and then I try to use: echo $myvar[0]; to try to display the first environment variable (regardless of the name of the variable), and I get the error "PHP Notice: Undefined offset: 0 in - on line 4". I even tried it with the with: echo $myvar[1]; under the assumption that maybe the first index is actually 1 instead of zero, but then I again get the error message "PHP Notice: Undefined offset: 1 in - on line 4". So it seems that it's EXPECTING me to index by the name of the entry only (like the string "PATH" for the index, instead of using an index number). I had assumed that a numerical index was a valid alternative to using the name of the array entry, based on what I've read online, but it's not working. ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.47 (proxied: 98.232.70.175) ---- Manual Page -- https://php.net/manual/en/function.getenv.php Edit -- https://main.php.net/note/edit/127036 Del: integrated -- https://main.php.net/note/delete/127036/integrated Del: useless -- https://main.php.net/note/delete/127036/useless Del: bad code -- https://main.php.net/note/delete/127036/bad+code Del: spam -- https://main.php.net/note/delete/127036/spam Del: non-english -- https://main.php.net/note/delete/127036/non-english Del: in docs -- https://main.php.net/note/delete/127036/in+docs Del: other reasons-- https://main.php.net/note/delete/127036 Reject -- https://main.php.net/note/reject/127036 Search -- https://main.php.net/manage/user-notes.php
