Hello,
i have problem with foreach when i call array by function.
Two uses two difference results.
example:
<?php
class Foo
{
function GetSomething()
{
return array ( array ( 1, 2, 3 ), array ( 4, 5, 6 ) );
}
function ListSomething()
{
// right result
$Text = '';
foreach $this -> GetSomething() as $Value )
$Text .= $Value [ 0 ];
}
}
//not working
$Text= '';
$Foo = new Foo();
// This construction return only first value PHP Version 5.1.2
foreach ($Foo->GetSomething() as $Value)
$text .= $Value[0];
// I must use this construction and then everything ok ..
foreach (array_values($Foo->GetSomething()) as $Value)
$text .= $Value[0];
?>
Do you anybody know, wheres problem?
Thanks!
