[PHP/MySQL] Function to return ALL selected rows

maZtah · 11-09-2007, 01:38 AM

Hi, I can't figure this out myself so maybe you've got an answer to my issue.

I want to create a function which returns (as the title says) all selected rows in an array. The next thing I want to do is loop through it and display all rows.

Something like this should do probably:

PHP Code:


			
public function query($szQuery) {

    $pResult = mysql_query($szQuery);

    while ($aRow = mysql_fetch_array($pResult)) {

        $aResult[] .= $aRow;

    }

    return $aResult;

}

To enter the query..

PHP Code:


			
$aResult = $pDatabase->query('SELECT * FROM Members');

Now my problem, how to loop through all the rows and displaying them?

You can just use the regular loop structures (foreach, for, while, and so on) since $aResult is just a normal array.

PHP Code:


			
foreach ($aResult as $aRow)
{
    // Do something for each row, perhaps
    echo $aRow['username'], ' smells!';
}

No, $aResult exists out of Arrays.

PHP Code:


			
print_r($aResult);

will echo

Code:

Array ( [0] => Array [1] => Array [2] => Array )

I may be wrong but i think:
$aResult[] .= $aRow;

Is your problem, it should be:
$aResult[] = $aRow;

But im not sure how much of an effect that will have, Salathe is correct in how he recommends it, but why would you want to add them all to an array and then loop through them AGAIN to access them? Seems a little odd to me, unless you have a certain situation.

That will return only the last row, bluesaga.

The point is that I want to output all the results found, without a mysql_fetch part outside the Database class.

bluesaga · 11-13-2007, 10:03 AM

Erm, no it won't.

Using array[] means it will create a row in the index incrementing the previous array index.

ie first time its ran:
array[0];

second time:
array[1];

However you can use something like this instead:

PHP Code:


			
class database
{

  function query($szQuery)
  {
     return mysql_query($szQuery);
  }

  function result($pQuery)
  {
    return mysql_fetch_array($pQuery);
  }
}

$db     = new database;
$query = $db->query("SELECT * FROM table");

while($result = $db->result($query))
{
   print_r($result);
}

Some conservatives have Coach Factory Outlet pushed that critique further, saying that Mr. Obama’s policies are too costly, often assist the wrong people Louis Vuitton Belts and could have the paradoxical effect of driving up college costs. The dispute turns not just on different Coach Factory Outlet assessments of how policies play out, but on differing philosophical views about the role of government. During Gucci Belts his time in office, Mr. Obama has sharply increased aid to low- and middle-income students, notably through the Pell Grant Coach Factory Outlet program, which grew from $14.6 billion given to 6 million students in 2008, to nearly $40 billion for Coach Factory Outlet almost 10 million students this year. His administration also made it easier to request aid, shortening the Coach Factory Online complex federal application and allowing people to transfer their financial information electronically from the Internal Coach Outlet Online Revenue Service database. But while many education experts laud his efforts, analysts of varying political Coach Outlet Online stripes have also questioned how much impact some of the president’s policies will have, noting that the prices Coach Online Outlet charged by colleges, and student borrowing, continue to climb.But behind the headlines about soaring costs, the Coach Factory Outlet Online reality is more complex and wildly uneven, because a growing number of students receive Coach Outlet Online financial aid, and only relatively high-income families pay those fast-rising sticker prices. Adjusted for Coach Factory Online inflation, the College Board calculates, the average net price changed little over the last decade at private Coach Factory Outlet schools, and rose only modestly at public ones.Defending federal spending, Arne Duncan, the secretary of Hermes Belts education, said that for more than 30 years, college prices had risen even when federal aid had not, leading him to believe Coach Factory Online there was zero correlation.

You’ve relativelyCoach Outlet recently arrived in New Delhi after living in two of Asia’s other great cities,Coach Outlet Store Online Tokyo and Hong Kong, for several years. Do these cities feel like they’re part of the same continent? Yes, and no. In terms Coach Factory Onlineof infrastructure, they couldn’t be more different. Getting regularCoach Outlet power and water at my house in New Delhi is never a sure thing, even though Coach Purse Outlet OnlineI’m paying the same rent that I paid in Tokyo and almost the same electricity prices. Both Hong Kong and Tokyo are also crowded places,Coach Factory Outlet Online but both cities are incredibly well planned and efficiently run. Efficient is not a word I would use to describe my Coach Bags Outlet Onlineday-to-day life in New Delhi. On the other hand, one thing that I think Hong Kong and New Delhi have in common isCoach Handbags Outlet a shared sense of optimism — a feeling that the best is yet to come. That’s definitely not the feeling you get in Tokyo,Coach Outlet Online or in the U.S. when I go home. It’s a big part of what I find addictive about living and working in this part of the world. You feel like you’re watching the future unfold.
