The 5.6 optimizer now attempts to evaluate them at compile time, which changes the execution behaviour. Test script: --------------- --TEST-- Terry_001 Constants get statically bound at compile time when Optimized --INI-- opcache.enable=1 opcache.enable_cli=1 opcache.optimization_level=-1 --SKIPIF-- <?php if (!extension_loaded('Zend OPcache') || php_sapi_name() != "cli") die("skip CLI only"); ?> --FILE-- <?php printf ("A=%s\n", getA()); const A="hello"; function getA() {return A;} --CLEAN-- --EXPECTF-- Notice: Use of undefined constant A - assumed 'A' in %son line %d A=A ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66251&edit=1
