I use a multidimensional array in a foreach loop, but i dont get the right results back.

array

$mainarray = array( 

    array('field_name'      => 'xx', 
          'email_label'     => 'xxxx', 
          'validation_type' => 'xxxxx',
          'validation_msg'  => 'xxxxxx'),

    array('field_name'      => 'xx', 
          'email_label'     => 'xxxx', 
          'validation_type' => 'xxxxx',
          'validation_msg'  => 'xxxxxx'),

            // more ....
}

foreach loop

foreach($mainarray as $fieldarray){
    foreach($fieldarray as $key => $value){     
        $body .= $value['email_label'].' - '. $value['field_name']; 
    }
}

i need the value's of the key called email_label and field_name, but i dont get the right results back

Since your code that appends to $body accesses indexes of $value, your original code was effectively written to work on a three-level array.

If your array is structured as you've posted, you don't need the inner foreach loop.

foreach($mainarray as $fieldarray) {    
    $body .= $fieldarray['email_label'].' - '. $fieldarray['field_name']; 
}

You only need one loop for this:

foreach($mainarray as $fieldarray){
    $body .= $fieldarray['email_label'].' - '. $fieldarray['field_name']; 
}

@user759235 Glad I could help :) When you go to accept an answer though I recommend accepting John Flatness', since he answered quicker than me with the exact same code, and has even added more information to his answer now to help explain why. –  YTowOnt9 Aug 25 '11 at 18:20

Try to use 

foreach($mainarray as $fieldarray){
    $body .= $fieldarray['email_label'].' - '. $fieldarray['field_name']; 
}
