xmlwriter - Rewrite existing attribute value from Xml String? -

-

is possible rewrite existing attribute xml string?

if have:

$xml_str = "<root>     <nodea attr1="value1"></nodea> </root>";  //rewrite $xml_str

how can find nodea , @ same time rewrite value1?

// save xml string physical path file_put_contents($xml_save_path.ds.$xml_filename, $xml_str);

you can use simplexml parse xml in php.

here's simplified version value1 , replace value2 echo new xml.

$xml_str = "<root>     <nodea attr1='value1'></nodea> </root>";  $doc = simplexml_load_string($xml_str);  $doc->nodea['attr1'] = 'value2';  echo $doc->asxml();

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 $row): ?> <div id="<?=$...
