[PHP-DB] array issue

[OpenSource]

hi ya'll

I am having a nightmare on this issue of mine.
I've got this array that I need to write to a file...
:::::::: sample code below ::::::::

while (something);
{
query data base

$r_ul=ifx_fetch_row($sideQuery4);

$type1 = array($rotation."\n");

switch ($r_ul['number'])
   {
    case '4';
    $linea = $type1;
    break;
   }

$final = $linea[0];

$my_array = array();
array_push ($my_array, $final);

}
 
$file = 'db_dump.dat';
$fp = fopen($file, "w");
fputs($fp, $my_array); <--- I would like to write the complete array into the file
fclose($fp);

kindly assist with this issue..

Thanks in advance
