php - Foreach loop printing duplicate last entry with output to data file -

-

i have foreach loop loops through present html , store data data file. issue (which has been raised before) last alliteration of foreach loop duplicated. using unset not work, writes data file within foreach loop! how can fix issue? want cut out duplicate , maintain writing data file...

my code:

// save data dat file $datafile = "datfile.dat"; $fh = fopen($datafile, 'w') or die("can't open file");  foreach($xml->drop $shipment) {     $connote_id = $shipment->header->bill_of_lading; // 20 chars     $output = sprintf("%-20.20s", $connote_id);     echo $output;     unset($shipment);     fwrite($fh, $output); }  $output .= "%%eof"; fwrite($fh, $output); echo "%%eof"; fclose($fh);

xml:

<?xml version="1.0" encoding="utf-8"?> <ishpmnt1> <drop> <header>   <bill_of_lading>vw038687030000006</bill_of_lading> </header> </drop> </ishpmnt1>

the issue resided understanding how fwrite works. writing last foreach 'output' variable twice, second adding %%eof hence why seemed duplicate sent through foreach loop.

fixed coding section:

echo $output; fwrite($fh, $output); } fwrite($fh, "%%eof");

thanks tried help! appreciated

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
