Summary: unexpected behaviour in 'foreach' syntax checking
Status: Bogus
Type: Bug
Package: Unknown/Other Function
Operating System: Linux
PHP Version: 5.3.5

ok, but, $key and $value(the iteration variables) still "living" out of
the foreach loop code, and make this really hard to debug. In other
languages, this don't happens.
May be for you, is not an error, but some notice of this isn't a bad
idea.

There is no syntax error there though.
foreach(...); is a valid loop construct and { expr; } is also a valid
construct
on its own.

Description:
------------
I found and unexpected behavior in the syntax checking. When you write a
';' after the open brace, the parser doesn't display an error or notice
message, and executes the code with the last element of the array. I
test this in php5.3 and php5.2.
This "innocent" ; is realy hard to debug.
The enviroments:

Test script:
---------------
<?php
function show_array(&$data_array){
foreach ($data_array as $key=>$value);
{
print "$key => $value\n";
if ( is_array( $value ) ){
show_array1( $value );
print "End of nested Array\n";
}
}
};
$evil_array = array (
'item1' => array ( 'item1_1' => array( 'item1_1_1' => 1,
'item1_1_2' => 2 ),
'item1_2' => array( 'item1_2_1' => 3,),
),
'item2' => '4');
show_array($evil_array);
?>
Output:
joac@pepino ~/ReposGcoop $ php bugphp.php
item2 => 4
Expected result:
----------------
I expect some error or notice for this syntax error.
Actual result:
--------------
joac@pepino ~/ReposGcoop $ php bugphp.php
item2 => 4
