Edit report at http://bugs.php.net/bug.php?id=52279&edit=1 ID: 52279 Updated by: aharvey@php.net Reported by: nefthy-php dot net at nefthy dot de Summary: non-breaking space not threated as white space -Status: Open +Status: Bogus Type: Bug Package: *Compile Issues Operating System: linux PHP Version: 5.3.2 New Comment: This is expected behaviour. To quote http://au2.php.net/manual/en/language.variables.basics.php: Note: For our purposes here, a letter is a-z, A-Z, and the bytes from 127 through 255 (0x7f-0xff). Exactly what happens in your example will depend on the encoding of the script, but if it's UTF-8, then the non-breaking space is represented as two bytes (C2; A0), both of which are above 7F and therefore are valid within a variable name.
