How do I iterate through an array and store it in $message for PHP mail()?

Previously I had issues with arrays and was graciously helped. My problem now is that I have the data in my array, but I need that to be stored into $message so that it will be included when mail() is called. I have chopped up my code and put the relevant piece below.

$to =       '"John Smith" <jsmith@theInter.net>';
$subject =  'Report';
$message =  '===========================================' . '<br>' .
//This is where I would want my array to be located; one element     printed on each line.
'===========================================' . '<br>' . '<br>' .
mail($to, $开发者_开发问答subject, $message);

My array ($fileList) contains one string per element. I want to have one element per line to be included in the above $message variable.

Thank you for any assistance you can give me.

$message = implode( "\n", $fileList );

use implode

implode("<br>", $fileList)

$message = 
    '===========================================<br>' .
    implode("<br>", $fileList) .
    '===========================================<br><br>';

implode is what you search
