    <p>This may be a simples question but i couldn't find the answer..</p> <p>If i have a class and declare the value of a variable within a function being called from a while statement and then use that variable later in another function when does that variable get changed to the next value in the array?</p> <p>ie.. I know that php executes code form top to bottom, but is that true with classes and functions being called from with in another function. Does php wait to go to the next item in the while statement until all functions and sub functions have been called or does it call a function then move to the next item in the list??</p> <pre><code>class myClass{ public $cust; function __construct(){ $sql = mysql_query("SOME QUERY"); while($row = mysql_fetch_array($sql)){ myClass::sendEmail(); } } function sendEmail(){ $this-&gt;cust = new selectDatabase(); $this-&gt;cust-&gt;table = "customer_main"; $this-&gt;cust-&gt;where = " WHERE customerID = '".$customerID."' "; $this-&gt;cust-&gt;getItems(); $this-&gt;cust-&gt;name = $name; $this-&gt;cust-&gt;email = $email; $sql = mysql_query("SELECT EmailTo, EmailFrom, EmailSubject, EmailBody FROM system_email"); $row = mysql_fetch_assc($sql); $to = myClass::dbReplace($row['EmailTo']); $From = myClass::dbReplace($row['EmailFrom']); $subject = myClass::dbReplace($row['EmailSubject']); $body = myClass::dbReplace($row['EmailBody']); $headers = "From: ".$from." \r\n"; $headers .= "Content-type: text/html\r\n"; $headers .= "Bcc: stoneops@cornell.edu\r\n"; $headers .= "X-Mailer: PHP/" . phpversion(); mail( $to, $subject, $body, $headers); } private function dbReplace($thisStr){ $x = substr_count($thisStr,"DB["); $z = 0; $holdArry = array(); while($z &lt; $x){ $rplStr = genEmail::findSubStr($thisStr); $t = substr_count($thisStr, "DB[".$rplStr."]"); $rplStr2 = split(':', $rplStr); $thisStr = str_replace("DB[".$rplStr."]", $this-&gt;{$rplStr2[0]}-&gt;{$rplStr2[1]}, $thisStr); $z = $z +$t; } return $thisStr; } private function findSubStr($str){ $pos = strpos($str, 'DB['); // outputs ER@EXAMPLE.com $pt1 = substr($str, ($pos + 3) ); $pos = strpos($pt1, ']'); $pt2 = substr($pt1, -1 * strlen(substr($pt1, $pos))); $pt2 = str_replace($pt2, "", $pt1); return $pt2; } } </code></pre>

    1. COWhy don't you try it? I see no better way of finding out. Also [RTFM](http://php.net/manual/en/language.functions.php).

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.
