note 54916 added to language.functions

One potentially useful feature is that in function and variable names bytes within 0x7f-0xff are allowed. This means you can use any UTF-8 in a variable name. As a simple example (this only uses latin-1 characters, but the concept is the same): <?php function ²($n) { return pow($n, 2); } function ¶($string) { return '<p>'.str_replace("\n\n", "</p>\n<p>", $string).'</p>'; } echo ²(4); //16 echo ¶("Some text\n\nbroken into paragraphs"); ?> You can use this to write PHP code in your native language, or even better make creative use of symbols like above to make your code understandable by everyone. ---- Manual Page -- http://www.php.net/manual/en/language.functions.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54916 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54916&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54916&report=yes Search -- http://master.php.net/manage/user-notes.php
