note 125142 added to userlandnaming.rules

#### Rules for PHP identifiers 1. A variable starts with the $ sign, followed by the name of the variable. 2. A variable name must start with a letter or the underscore character. 3. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ). 4. Identifiers are case sensitive. Therefore, a variable named $unicorn is different from a variable named $Unicorn, $uNicOrn, or $unicorN. 5. Identifiers can be any length. 6. An identifier name can’t be identical to any of PHP’s predefined keywords. ---- Server IP: 45.112.84.4 Probable Submitter: 101.0.109.162 (proxied: 101.100.156.18) ---- Manual Page -- http://php.net/manual/en/userlandnaming.rules.php Edit -- https://master.php.net/note/edit/125142 Del: integrated -- https://master.php.net/note/delete/125142/integrated Del: useless -- https://master.php.net/note/delete/125142/useless Del: bad code -- https://master.php.net/note/delete/125142/bad+code Del: spam -- https://master.php.net/note/delete/125142/spam Del: non-english -- https://master.php.net/note/delete/125142/non-english Del: in docs -- https://master.php.net/note/delete/125142/in+docs Del: other reasons-- https://master.php.net/note/delete/125142 Reject -- https://master.php.net/note/reject/125142 Search -- https://master.php.net/manage/user-notes.php
