I suggest to use a debugger.

It would be nice to be able to do something like function foo() { echo 'bar'; } $foo = &foo; $foo(); And ultimately, override the defined function: function foo() { echo 'bar'; } $oldFoo = &foo; foo = function() use ($oldFoo) { $oldFoo(); echo 'bar'; } foo(); // will print 'foobar'; There are several uses for this, just look at the way closures are commonly used in javascript. It's really useful for debugging, as a function can be substituted easily. Though this probably isn't possible due to the clear distinction php makes between functions and variables. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=49100&edit=1
