array_walk() PHP4 won't reset() the array before walking,
it will start at the current position instead of the
first element as php3 does

? is this a bug or a feature ?

if it is a feature, than the example
in the documentation has to be changed ...

<pre>
$fruits=array("d"=>"lemon","a"=>"orange","b"=>"banana","c"=>"apple");

function test_alter( &$item1, $key, $prefix ) {
  $item1 = "$prefix: $item1";
}

function test_print( $item2, $key ) {
  echo "$key. $item2<br>\n";
}

array_walk( $fruits, 'test_print' );
array_walk( $fruits, 'test_alter', 'fruit' );
array_walk( $fruits, 'test_print' );
</pre>

will need a 'reset($fruits);' before call #2 and #3 
of array_walk to work
