ID: 60171 Comment by: artificialmagic at hotmail dot com Reported by: invictible at live dot co dot uk Summary: Suggestion for new function Status: Wont fix Type: Feature/Change Request Package: Unknown/Other Function Operating System: Windows PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: Who would ever think this was useful? Previous Comments: ------------------------------------------------------------------------ [2011-10-30 03:39:46] invictible at live dot co dot uk Expressions such as >, >+ aka something like the comparison operators except, in function form. ------------------------------------------------------------------------ [2011-10-30 00:52:48] cataphr...@php.net This is the purpose of eval (though it would probably be better â including versatile â to parse the expression yourself), the "security issues" (really, input validation) can be handled by analyzing the tokens in the strings; see token_get_all(). Besides, this request is very vague â for instance it doesn't specify which subset of the expressions space would be admissible and gives a rationale for it. Won't fix. ------------------------------------------------------------------------ [2011-10-29 21:28:06] invictible at live dot co dot uk Description: ------------ I've been looking for a solution on PHP as I need some way to evaluate expressions within strings. Since with if: $str = '5>6'; if($str) Would evaluate as true regardless of the expression. A good possible solution for this may be a function for evaluating the expressions in the string, eg. evalexp($str); which would return true or false based on the expression within the string. Eval is an alternative however, it can create security issues when used with user provided content for obvious reasons. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60171&edit=1
