Change PHP PEAR for mysql connection -

-

i'm working along tutorial on how import excel data mysql. problem have used pear: database connection , don't know how works. convert code commonly used mysql connection string. i'm sure i've never seen pear or db::connect used before.

here's code below.

<?php require_once( "db.php" );  $data = array();  $db =& db::connect("mysql://root@localhost/names", array()); if (pear::iserror($db)) { die($db->getmessage()); }  function add_person( $first, $middle, $last, $email ) {  global $data, $db;   $sth = $db->prepare( "insert names values( 0, ?, ?, ?, ? )" );  $db->execute( $sth, array( $first, $middle, $last, $email ) );   $data []= array(    'first' => $first,    'middle' => $middle,    'last' => $last,    'email' => $email  ); }  if ( $_files['file']['tmp_name'] ) {  $dom = domdocument::load( $_files['file']['tmp_name'] );  $rows = $dom->getelementsbytagname( 'row' );  $first_row = true;  foreach ($rows $row)  {    if ( !$first_row )    {      $first = "";      $middle = "";      $last = "";      $email = "";       $index = 1;      $cells = $row->getelementsbytagname( 'cell' );      foreach( $cells $cell )      {        $ind = $cell->getattribute( 'index' );        if ( $ind != null ) $index = $ind;         if ( $index == 1 ) $first = $cell->nodevalue;        if ( $index == 2 ) $middle = $cell->nodevalue;        if ( $index == 3 ) $last = $cell->nodevalue;        if ( $index == 4 ) $email = $cell->nodevalue;         $index += 1;      }      add_person( $first, $middle, $last, $email );    }    $first_row = false;  } } ?> <html> <body> these records have been added database: <table> <tr> <th>first</th> <th>middle</th> <th>last</th> <th>email</th> </tr> <?php foreach( $data $row ) { ?> <tr> <td><?php echo( $row['first'] ); ?></td>< <td><?php echo( $row['middle'] ); ?></td>< <td><?php echo( $row['last'] ); ?></td>< <td><?php echo( $row['email'] ); ?></td>< </tr> <?php } ?> </table> click <a href="list.php">here</a> entire table. </body> </html>

i assume post want mysql_* functions, not newer mysqli class. (personally, prefer latter oo-interface.)

then change

$db =& db::connect("mysql://root@localhost/names", array()); if (pear::iserror($db)) { die($db->getmessage()); }

to

$db = @mysql_connect('localhost', 'user', 'pass') or die ( mysql_error() ); mysql_select_db('db_name', $db);

and change

$sth = $db->prepare( "insert names values( 0, ?, ?, ?, ? )" ); $db->execute( $sth, array( $first, $middle, $last, $email ) );

to

$query = sprintf(          'insert names values( 0, "%s", "%s", "%s", "%s" )' ,         mysql_real_escape_string($first),         mysql_real_escape_string($middle),         mysql_real_escape_string($last),         mysql_real_escape_string($email)     );  mysql_query($query, $db);

php - Accessing POST data in Facebook cavas app -

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
