    <p>I'm extending mysqli in a database class. I've noticed that calling the parent constructor takes nearly 2 seconds. It is possible, I suppose, that it is my environment since I am developing on my desktop prior to deployment. But that does not seem very likely to me.</p> <p>Environment: </p> <ul> <li>OS - Windows 7 Pro</li> <li>WAMP server</li> <li>Apache/2.2.17 (Win32) </li> <li>PHP 5.3.4 </li> <li>MySql ver 5.1.53 </li> <li>NetBeans IDE 6.9.1</li> </ul> <p>The code in question:</p> <pre><code>class DGMysqliLink extends MySQLi { public function __construct($aDSN) { // Construct the DSN $aDSN['dbhost'] = (empty($aDSN['dbhost']))?ini_get("mysqli.default_host"):$aDSN['dbhost']; $aDSN['dbuser'] = (empty($aDSN['dbuser']))?ini_get("mysqli.default_user"):$aDSN['dbuser']; $aDSN['dbpass'] = (empty($aDSN['dbpass']))?ini_get("mysqli.default_pw"):$aDSN['dbpass']; $aDSN['dbname'] = (empty($aDSN['dbname']))?'':$aDSN['dbname']; $aDSN['dbport'] = (empty($aDSN['dbport']))?ini_get("mysqli.default_port"):$aDSN['dbport']; $aDSN['dbsock']= (empty($aDSN['dbsock']))?ini_get("mysqli.default_socket"):$aDSN['dbsock']; // Instantiate the object by invoking the parent's constructor. // This takes nearly 2 seconds parent::__construct($aDSN['dbhost'],$aDSN['dbuser'],$aDSN['dbpass'], $aDSN['dbname'],$aDSN['dbport'],$aDSN['dbsock']); // If there are any errors, deal with them now if($this-&gt;connect_error){/* Do some stuff */} } } </code></pre> <p>Why does calling this constructor take so long and how can I fix it?</p>

    1. COare you suggesting that calling the mysqli constructor directly doesnt take 2 seconds? part of debugging is minimizing the code near the problem, so get rid of your class for now.

    2. CONo, not suggesting that. Hadn't considered calling it directly. Will do and re-comment.

    3. COSo, using the code below takes about the same amount of time. I'm not using any sort of benchmarking tactics, just "one one-thousand, two one-thousand,etc." Again, sorry for the formatting.<br /> // Construct the DSN $aDSN['dbhost'] = 'localhost'; $aDSN['dbuser'] = 'dbuser'; $aDSN['dbpass'] = 'dbpass'; $aDSN['dbname'] = 'dbname'; $oDBC = new mysqli($aDSN['dbhost'],$aDSN['dbuser'],$aDSN['dbpass'],$aDSN['dbname']);

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.
