stopping a function from another function

IN PHP, Is it possible that I could stop a function from an internal function?, for example

function_1(){
   ......
function2();
....
}

Can I stop function1 using a sentence in function2 but avoiding stopping the whole script?

You can do this if you capture the return value of your second function.

function my_first_function() {
  // some code
  if( !my_second_function() ) {
     return;
  }
}

function my_second_function() {
  return false;
}

my_first_function();

Of course you need to modify it to meet you needs but that should get you started.

You can use the RunKit extension, which lets you redefined/rename functions. By default it only allows this to be done on user-defined functions, but there's a php.ini setting to enable it for internal functions as well.

That would let you do something like:

runkit_function_rename('print', 'internal_print');
function print(...) {
   echo 'welcome to my own implementation of print';
}

However, messing with internal functions can basically break PHP, so use at your own risk.
