Question

I am new to PHP so please excuse my mess. This is a very complicated query for somebody like me to change.

Please see the query below. Right now all results are being displayed in the $row[‘Post’]; Instead I want to be able to do something like:

$somerow = $row[‘some_row’];
$somerow2 = $row[‘some_row2’];

and then be able to use it anywhere with the $variables used above.

I tried using this below but it didn’t work:

if($rows == 0)
{
print("");

}
elseif($rows > 0)
{
while($row = mysql_fetch_array($query))
{

$postid = htmlspecialchars($row['post_id']);
$postname = htmlspecialchars($row['post_name']);


print("$postname and the id is $postid");
}

}

How can i achieve this?

You could store each row in an array and later on pick the rows out you want to use.

if($rows == 0)
{
    print("I have no rows!");
}
else
{
   $allrows = array();
   while($row = mysql_fetch_array($query))
   {
       $allrows[] = $row;
   }
   $row1 = $allrows[0];
   $row2 = $allrows[1];
   echo $row1['Post']; // Print out first row
   echo $row2['Post']; // Print out second row
   var_dump($allrows); // Print out all the rows and the structure of this array
}

If you then want to use those variables everywhere, you will need to make them global, but I would advice against using global variables for things like that or for anything in general for that matter.
