[SOLVED] Sorting through multidimensional array

[hostfreak]

I've got an array that produces the following:

Array
(
    [username] => Array
        (
            [0] => Username must be entered
            [1] => Username must be at least 6 characters
        )

    [Password] => Array
        (
            [0] => Password must be entered
        )

)

 

What would be the best way to sort through it. I know a method (see below), but would like opinions on what people think is the way to go.

 

Method I am currently using:

foreach ($this->errors as $errors) //$this->errors is the array
{
    while (list($k, $v) = each ($errors))
    {
        echo $v . '<br />';
    }
}

 

To me it seems a little makeshift seeing as I don't actually need to list the key.

I'd use a 2nd foreach loop:

 

foreach ($this->errors as $errors) //$this->errors is the array
{
    foreach ($errors as $error)
    {
        echo $error . '<br />';
    }
}

Not sure why that didn't cross my mind. Anyways works great and looks a lot better to me. Thanks mjdamato.

Sorry to bring this topic back up, however there is another question I would like to ask. I want to be able to group the errors under what multidimensional array they fall under. So I would need to extract the name of the array, for example:

[username] => Array //Only want to e

 

I would need to extract "Username". All suggestions are appreciated, thanks.

<?php

foreach ($this->errors as $error_cat => $error_ary) //$this->errors is the array
{
    echo "<b>$error_cat</b><br />\n";
    foreach ($error_ary as $error)
    {
        echo "$error<br />\n";;
    }
}

?>
