Exit Function Early

[bsmither]

There is a function (that cannot be changed) which has an include:

 

<?php
function a() {
  include 'file.php';
  echo 'work';
}
?>
 
==file.php==
<?php
echo 'play';
## Need to leave a() now!
?>

The included file can be changed.

 

I would like a way for file.php to cause PHP to return out of the function a(). A return; statement in file.php has PHP pick up execution with the statement following include.

 

What is there in PHP that will allow returning out of a() at some point in file.php?

return will work as expected.

 

<?php
function a() {
  include 'file.php';
  echo 'work';
}

file.php

<?php

echo 'play';
return;
echo 'this will not be reached';

Sorry, I wasn't clear. I want a statement in file.php to exit out of a(). In other words, I do not want the last statement in a(), which is echo 'work';, to be executed at all.

Yeah, if you can't change that function, that isn't going to happen.

Actually, there is a library that might be able to help you, just can't think of the name of it off the top of my head.

 

Give me a second.

I've not used this myself, just remember reading about it: http://go.aopphp.com

 

Looks interesting yet scary.
