Operating system: All
PHP version:      Next Minor Version
Package:          PHP Language Specification
Bug Type:         Feature/Change Request
Bug description:Returning from multiple function calls

Description:
------------
function analyze($anyParameter)
{
   foreach($anyParameter as &$v)
      b($v);
}

function b(&$obj)
{
   foreach($obj as $line)
   {
      $res=c($line); 
   }
   if(...) 
   {
      ...
      $res=b(substr($line,3)); /* recurrent function */
      ...
   } 
   ...
}

function c(&$line)
{
   if($line=='1') 
      return 3;
   if($line=='2') 
      return 4;
   if($line=='unexpected data')
      [analyze] return false; /* return from previous calls 
                                 and return 'false' from 
                                 'analyze' function and 
                                 continue execution from
                                 next instruction after 
                                 last 'analyze' call. */
   return -1;
}

Test script:
---------------
No test script, the functionality will help faster return from multiple
calls, for example analyzing jpeg, gif or odt files. It is the common
situation that the analyzing function identyify unexpected data and the
analysis must by broken due to nonsense data and returns error code. 

It is possible to write code without this enhancement but the code will
be longer  and will contain additional conditions slowing execution of
multiple nested calls. 

Expected result:
----------------
additional syntax 

[functionName] return result;
