Query on Nested Functions

[Squiggles]

Hi all.

Just a couple of questions regarding functions. I'm currently putting up a site that requires a table template to contain information for the site. Now, for the questions:

1. Are nested functions supported by PHP?
2. If so, if I were to construct a function nested in a function, could I declare the name of the function to be executed within the arguements of the parent function?

(Ex. function_1_name($subfunction_name))

Therefore, the code would be as follows:

function function_one($subfunction_one)
{
$subfunction_one();
}

is this code possible?

yes and yes. you described what php calls a variable function.

Yes.

from the manual Any valid PHP code may appear inside a function, even other functions and class definitions.

function foo($bar, $args)
{
  function baz($args)
  {.....}
  function wibble($args)
  {.....}
  function womble($args)
  {.....}
  $bar($args);
}

...
foo('wibble',$stuff);

You might want to look into using Objects. I can't see why you would want to do it the way you posted.
