_FILES array
An <input type="file" name="foo"> produces this
<?php
array (
'foo' =>
array (
'name' => '',
'type' => '',
'tmp_name' => '',
'error' => 4,
'size' => 0,
),
)
?>$_FILES array. What do you think foo[bar] will produce?
<?php
array (
'foo' =>
array (
'name' =>
array (
'bar' => '',
),
'type' =>
array (
'bar' => '',
),
'tmp_name' =>
array (
'bar' => '',
),
'error' =>
array (
'bar' => 4,
),
'size' =>
array (
'bar' => 0,
),
),
)
?>

I don't get it. You mean
I don't get it. You mean dumping $_FILES['foo']['bar'] will print that?
No, <input type="file"
No,
<input type="file" name="foo[bar]">and
<?phpvar_dump($_FILES);

$_FILES['foo']['name']['bar'];

I don't know where to submit a solution but here you go; What is the output of this and why?
<?phpfor ($i = 0; $i < 5; ++$i) {
if ($i == 2)
continue
print "$i\n";
}
?>
The output is: 2 Your code is
The output is:
2
Your code is equivalent to:
<?phpfor ($i = 0; $i < 5; ++$i) {
if ($i == 2) {
continue print "$i\n";
}
}
?>
From http://ru.php.net/manual/en/control-structures.continue.php:
continue accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of.
From http://ru.php.net/manual/en/function.print.php:
Print returns 1, always.
That's explains such kind of behavior :)

The breville juice fountain
The breville juice fountain elite 800jexl is popularly known as the Cadillac of juicers but does it really live up to its claims?
The breville 800jexl has an Italian made electronic motor that increases power when it’s under heavy use in order to maintain filter revolutions. This breville 800jexl juice fountain elite is also “smart” because it has the technological ability to regulate the power needed depending on what’s being juiced.
