Calling a function defined within a funcion

[Andrew Boothman]

Hi,

This may be the dumbest question ever, but in the following code (using
PHP 4.3.8) how do I call b() from within a()?

class test {
function a() {
print "a called";
b();

function b() {
print "b called";
}
}
}

using "b()" (as in the code above) doesn't work, neither does $this->b()
or test::b(), so how do I call it?

Thanks!

Andrew

You will need to define the function before calling it.

first, you would need to define function b prior to calling it. Even when
you would do so, than you would be able to call function a only once, since
second call to a would try to define function b() which would be by that
time allready defined.

In php there is no notion of local function, as you would know it from other
languages like Pascal. The construct you are using might misslead you, that
you are defining function b local to function, but you are not, you are just
within code of a executing statement that in effect defines global function
b().

No, the function needs to be defined before you can call it - that's not the
same thing at all - unlike 'C', PHP will quite happily call functions
defined below its invocation in the source file.

To call a METHOD within an OBJECT, you need to instantiate the object and
reference the method e.g.

class test {
function a() {
print "a called";
$this->b(); // ********

function b() {
print "b called";
}
}
}

using "b()" (as in the code above) doesn't work, neither does $this->b()
or test::b(), so how do I call it?

I guess you didn't create an instance -

$testObj = new test;
$testObj->a();
