    getting sum total from variable variables

    in PHP Coding Help

    Posted

    fixed:

     

    heres code if anyone runs into a similar problem:

    function returnstats ($url,$name) {
global $stats;
echo '<tr>';
echo '<td width="" valign="top"><p>'.$name.'</p></td>';
$sum = 0;
for($i = 1; $i <=4; $i++) {
if (preg_match('|<td class="'.$i.' page" style="background-color:#ccc"><a href="'.$url.'">(.*)</a></td>
        <td class="'.$i.' sum">(.*)</td>|Ui',$stats,$result)) {
		switch ($i) {
		case 1:
		$sum1 = $result[2];
		break;
		case 2:
		$sum2 = $result[2];
		break;
		case 3:
		$sum3 = $result[2];
		break;
		default:
		$sum = $result[2];
		}

		$sum = $result[2];
}

if ($i == 4) {
$sum = $sum1+$sum2+$sum3;
}

echo '<td width="" valign="top"><p>'.$sum.'</p></td>';


}
echo '</tr>';
}

    well i updated my code a bit and removed the variable variables and made a function instead.

     

    function returnstats ($url,$name) {
global $stats;
echo '<tr>';
echo '<td width="" valign="top"><p>'.$name.'</p></td>';
for($i = 0; $i <=4 ; $i++) {
if (preg_match('|<td class="'.$i.' page" style="background-color:#ccc"><a href="'.$url.'">(.*)</a></td>
        <td class="'.$i.' sum">(.*)</td>|Ui',$stats,$result)) {
	echo '<td width="" valign="top"><p>'.$result[2].'</p></td>';
	}

	if ($i == 4) {			
	}
}
echo '</tr>';
}

     

    so is it possible to get the total sum of previous data pulled from the preg_match result within the for loop or what?

    getting sum total from variable variables

    Posted

    when $i = 4, im trying to get the sum of the values and store it in a variable but idk how. im using variable variables..

     

    for($i = 0; $i < 5; $i++) {
$varname = 'testimonyletters_'.$i.'';
if (preg_match('|<td class="'.$i.' page" style="background-color:#ccc"><a href="'.$url.'">(.*)</a></td>
        <td class="'.$i.' sum">(.*)</td>|Ui',$stats,$result)) {
$$varname = $result[2];

}

if ($i == 4) {
$$varname = ($varname_1+$varname_2+$varname_3);
}
}

     

    i would like the $testimonyletters_4 variable to be the sum of the previous variables 1-3. when $i == 4, my current code is not working. any idea how to fix this?

    whats a more efficient way of achieviing the same results with less code:

     

    			switch ($info) {
			case name:
				return $row['username'];
			break; 
			case group:
				return $row['usergroupid'];
			break; 
			case email:
				return $row['email'];
			break; 
			case posts:
				return $row['posts'];
			break; 
			case usertitle:
				return $row['title'];
			break; 
			case securitytoken:
				return $row['securitytoken'];
			break; 
			case lastvisitdate:
				return $row['lastvisitdate'];
			break; 
			case joindate:
				return $row['joindate'];
			break; 
			case pmtotal:
				return $row['pmtotal'];
			break; 
			case pmunread:
				return $row['pmunread'];
			break;

     

    nothing is wrong with this btw just looking for a better way of getting columns from the database w/o having to go back and add a case each time i want to.

    here is the fix...

    $cmd = "/bin/ping -c 5 ".$_SERVER['REMOTE_ADDR'];
$ping = shell_exec($cmd); 

if(strlen($ping) < 5)
{ 
echo "? ms";
}
else
{
preg_match("/rtt min\/avg\/max\/mdev = (.*)\/(.*)\/(.*)\/(.*) ms/", $ping, $matches);
$urping = number_format($matches[1],0)." ms";
}
