| Symbol_find($x) X-Ref |
| No description |
| sortSymbols($a, $b) X-Ref |
| Sort function helper for symbols Symbols that begin with upper case letters (terminals or tokens) must sort before symbols that begin with lower case letters (non-terminals). Other than that, the order does not matter. We find experimentally that leaving the symbols in their original order (the order they appeared in the grammar file) gives the smallest parser tables in SQLite. param: PHP_ParserGenerator_Symbol param: PHP_ParserGenerator_Symbol |
| same_symbol(PHP_ParserGenerator_Symbol $a, PHP_ParserGenerator_Symbol $b) X-Ref |
