zend-parser.y problems

Hey folks- Basically, the following code will cause an error: #!./php -q <? define("SOME_CONSTANT", "./"); #The following causes a "expecting `T_CONSTANT_ENCAPSED_STRING'" error: require_once(SOME_CONSTANT."somefile"); #These will not cause that error: include_once(SOME_CONSTANT."somefile"); require(SOME_CONSTANT."somefile"); require_once(SOME_CONSTANT."somefile"); ?> So after searching through the Zend code a bit, specifically zend-parser.y:716, I found this inconsistency: 1.82 (andi 02-Jul-00): | T_INCLUDE expr { do_include_or_eval(ZEND_INCLUDE, &$$, &$2 CLS_CC); } 1.67 (andi 10-Mar-00): | T_INCLUDE_ONCE expr { do_include_or_eval(ZEND_INCLUDE_ONCE, &$$, &$2 CLS_CC); } 1.10 (zeev 22-Apr-99): | T_EVAL '(' expr ')' { do_include_or_eval(ZEND_EVAL, &$$, &$3 CLS_CC); } 1.85 (zeev 09-Aug-00): | T_REQUIRE expr { do_include_or_eval(ZEND_REQUIRE, &$$, &$2 CLS_CC); } 1.85 (zeev 09-Aug-00): | T_REQUIRE_ONCE use_filename { do_include_or_eval(ZEND_REQUIRE_ONCE, &$$, &$2 CLS_CC); } By changing line 720 from this: | T_REQUIRE_ONCE use_filename { do_include_or_eval(ZEND_REQUIRE_ONCE, &$$, &$2 CLS_CC); } to this: | T_REQUIRE_ONCE expr { do_include_or_eval(ZEND_REQUIRE_ONCE, &$$, &$2 CLS_CC); } the problem (as it exists in my scope) is fixed. Zeev, Andi, can either of you shed some light on this code? I don't know the Zend internals well enough to understand the intended functionality of use_filename vs expr. Thanks John
