    <p>I'm using php files to get data from mysql to iPhone app, to illustrate my mean I used this code in php </p> <pre><code>&lt;?php $host = "localhost"; $user_name = "user_name"; $password = "password"; $db_name = "db_name"; $con = mysql_connect($host,$user_name,$password)or die (mysql_error()); mysql_select_db($db_name)or die (mysql_error()); mysql_query("set names utf8"); $SQL= "SELECT * FROM emails WHERE 1"; $RS = mysql_query($SQL) or die(mysql_error()); mysql_query("set character_set_server='utf8'"); while($row=mysql_fetch_assoc($RS)) $output[]=$row; $json_encode =json_encode($output); $utf8_decode = utf8_decode($json_encode); echo $json_encode; mb_convert_encoding($json_encode, 'UTF-8'); $html_entity_decode = html_entity_decode($json_encode); </code></pre> <p>?></p> <p>and in iPhone I used this code:</p> <pre><code>NSString *phpUrl = @"url of my php file"; SBJsonParser *parser = [[SBJsonParser alloc] init]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:phpUrl]]; NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; NSArray *statuses = [parser objectWithString:json_string error:nil]; for (NSDictionary *status in statuses) { NSString *sEmailID = [status objectForKey:@"ID"]; NSString *sEmail = [status objectForKey:@"Email"]; NSString *sPassword = [status objectForKey:@"Password"]; NSString *sSMTP = [status objectForKey:@"SMTP"]; } </code></pre> <p>and this works ok for me and I got my data. I also uses this way many times in my app. But my problem is that the request and response leads to decrease the speed of my app and made it works so slowly. Is there are any ways to decrease the speed of request and response or is there are any alternative ways instead of this? Thanks in advance.</p>

    1. COPlease don't use the `mysql_*` functions as they are in the [deprecation process](http://news.php.net/php.internals/53799). Use [MySQLi](http://php.net/manual/en/book.mysqli.php) or [PDO](http://php.net/manual/en/book.pdo.php) instead and [be a better PHP Developer](http://jason.pureconcepts.net/2012/08/better-php-developer/).

    3. COAre you creating/destroying the connection to the server for every request? Because that would likely cause you a lot of overhead and slow things down.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
