#46742 [Com]: is_numeric function not working as per "common sense"

ID: 46742 Comment by: zyss at mail dot zp dot ua Reported By: ben at ajmadison dot com Status: Open Bug Type: Feature/Change Request Operating System: any PHP Version: 5.2.6 New Comment: It shouldn't. is_numeric() works just in the same way as in other languages, specifically as described in PHP docs: "Numeric strings consist of optional sign, any number of digits, optional decimal part and optional exponential part. Thus +0123.45e6 is a valid numeric value. Hexadecimal notation (0xFF) is allowed too but only without sign, decimal and exponential part." This doesn't prevent one from implementing his own algorithm with a custom function.

Since the comma is used just for visual representation, the number represented is still numeric and is_numeric function should return true. Reproduce code: --------------- echo is_numeric("1,343.32"); Expected result: ---------------- true Actual result: -------------- false ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46742&edit=1
