[php-src] Issue #9263: PHP 8.2.0beta2 emits false positive deprecation warning before fatal error for `"{$g{'h'}}"`;

Issue: https://github.com/php/php-src/issues/9263 Author: TysonAndre ### Description The following code: ```php <?php $x = "{$g{'h'}}"; ``` Resulted in this output: ``` Deprecated: Using ${expr} (variable variables) in strings is deprecated, use {${expr}} instead in php shell code on line 1 Fatal error: Array and string offset access syntax with curly braces is no longer supported in php shell code on line 1 ``` But I expected this output instead: ``` Fatal error: Array and string offset access syntax with curly braces is no longer supported in php shell code on line 1 ``` (i.e. there is no use of ${} for string interpolation) The cause is that the constants used for ast node flags have identical values, causing this ambiguity. #define ZEND_DIM_ALTERNATIVE_SYNTAX (1 << 1) /* deprecated curly brace usage */ #define ZEND_ENCAPS_VAR_DOLLAR_CURLY_VAR_VAR (1<<1) ### PHP Version PHP 8.2.0beta2 ### Operating System _No response_
