Array returning as, 'Array'

Napster

So I have this simple code on my site that goes like this:


  $house = array("Red","Ornange","Yellow","Blue");

  foreach ($house as $key) {

echo "&nbsp;&nbsp;" . $key . " :: <br>";

  }

But Instead of displaying, "

Red ::
Orange ::
Yellow ::
Blue ::

It is displaying as, "

Array ::
Array ::
Array ::
Array ::

Why is it doing this and how do I fix it? I tried going


  $house[0] = "Red";

  $house[1] = "Orange";

  $house[2] = "Yellow";

  $house[3] = "Blue";

But that did not help. Thank you in advanced.

Change this:
foreach ($house as $key) {

to:
foreach ($house as $key => $value) {

and then echo the $value

$house = array("Red","Ornange","Yellow","Blue"); 

foreach ($house as $key => $value) { 
    echo "$value<br>"; 
}

Ok thank you. That works.

Though I have gone

foreach ($array as $key) {

}

Before and it has worked properly. Why did it not do it this time?

foreach ($array as $key)

SHOULD work. in this case, $key is actually the value.

your problem is your array is not constructed as you have shown us. you have a multidimensional array(more arrays within the array)

to see its structure, try
print_r($array);

No that is not it, I do not have arrays in arrays. I think our server updated something because on every site where a foreach is used it has to be fixed like this.

really????

so this doesnt work?


$nums = array(
    'one',
    'two',
    'three',
);

foreach ($nums as $num) {
    echo "$num<br>";
}

if that doesnt work then your host needs to fix thier php installation. maybe there is a bug in thier version of php.

you should not have to do
foreach ($nums as $key => $value)

as that is an optional syntax
