Function decorator(Python) like behaviour in PHP [closed]

[emule06]

I want to be able to wrap a PHP function by another function, but leaving its original name/parameter list intact.For instance:\[code\]function A() { print "inside A()\n";}function Wrap_A() { print "Calling A()\n"; A(); print "Finished calling A()\n";}// <--- Do some magic here (effectively "A = Wrap_A")A();\[/code\]Output:\[code\]Calling A()inside A()Finished calling A()\[/code\]
