Bug #53860 [NEW]: unexpected behaviour in 'foreach' syntax checking

From: Operating system: Linux PHP version: 5.3.5 Package: Unknown/Other Function Bug Type: Bug Bug description:unexpected behaviour in 'foreach' syntax checking Description: ------------ I found and unexpected behavior in the syntax checking. When you write a ';' after the open brace, the parser doesn't display an error or notice message, and executes the code with the last element of the array. I test this in php5.3 and php5.2. This "innocent" ; is realy hard to debug.
