Array for displaying multiple message error

So I am tyring to do the extra credit for this course. I am having trouble figuring out how to have the array hold all the values of the errors. What I did and got stuck was the following:

$error_message = array(); $error_message = array($error_message); // Here I am trying to hold the error message in a variable, since all I can reference from the excersices are text values in the arrays Im confused.

Then under the else statement before the form I run a loop:

foreach ($error_message as $error) { // Here I guess at least I would see the index number echo but I see nothing on the form when I run it. echo $error; }

Hello. You can't have an array called $error_message, if you'r receiving a value and also holding it in $error_message. Otherwise it would be like looping through an empty array, and they would conflict. Give the array a different name. Loop through all you error messages and put them into $error, then I believe the syntax is, $error_message [ ] = $error; This places all the $error values into the array. Then return the array if it's a function.

Hope this helps :)

Im sorry Im a little confused with your explanation.

Yes, I hold all the errors under a variable called: $error_message.

So are you saying:

$errors = array(); $errors = $error_message [ ];

then

foreach($errors as $error { echo $error; }

```php $errors = array( ); foreach $error_message as $error { $errors [ ] = $error; } return $errors;
