Anyway, character sets can't be auto-magically guessed (not to mention that they can be mixed), so you can't expect case-sensitivity to work out of the box like that. However, the following should work: <?php declare(encoding='WINDOWS-1251'); // assuming this is the file character set function тест() { echo "ok\n"; } тест(); ТЕСТ(); It doesn't. As I said - it triggers a syntax error for me and doesn't recognize the characters at all. ------------------------------------------------------------------------ [2014-02-07 20:54:34] mail at mkharitonov dot net Description: ------------ Manual page: http://www.php.net/manual/en/functions.user-defined.php Actual text: "Function names are case-insensitive, ...". Expected text: "Function names are case-insensitive for A-Z chars and case-sensitive for chars with codes from 127 through 255 (0x7f-0xff), ...". Test script: --------------- <?php /* File charset is "windows-1251" */ function english() { print 'ok '; } english(); ENGLISH(); function кириллица() { print 'ok '; } кириллица(); КИРИЛЛИЦА(); Expected result: ---------------- ok ok ok ok Actual result: -------------- ok ok ok Fatal error: Call to undefined function КИРИЛЛИЦА() in ... on line 9 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66668&edit=1
