Grouping WHILE loop results - php

Question

At the moment I'm using a WHERE loop to display 2 columns of information in my database. Here's the code:
$sql2 = sprintf($rawsql2, mysql_real_escape_string($id));
$result2 = mysql_query($sql2);
/*These if & while statements decide whether or not the information should be displayed. If no results are returned from the query above then an alternative message is shown.*/
if (mysql_num_rows($result2) > 0) {
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC)) {
echo $row["open"] . "-" . $row["close"] . "<br/><br/>";
}
}
else {
echo "Error";
}
This outputs the following:
08:00:00-12:30:00
13:30:00-16:30:00
09:00:00-17:00:00
18:00:00-20:00:00
09:00:00-17:00:00
18:00:00-20:00:00
08:00:00-17:00:00
18:00:00-20:00:00
09:00:00-17:00:00
18:00:00-20:00:00
Now, what I need to do is group every 2 lines that are turned so instead it would look like:
08:00:00-12:30:00 13:30:00-16:30:00
09:00:00-17:00:00 18:00:00-20:00:00
09:00:00-17:00:00 18:00:00-20:00:00
08:00:00-17:00:00 18:00:00-20:00:00
09:00:00-17:00:00 18:00:00-20:00:00
Is this possible? Thanks for any help
edit: Thanks for all the answers everyone...I used Shakti's answer as it was the first one I saw but by the looks of it everyone's are pretty similar.

Answer 1

if(mysql_num_rows($result2) > 0)
{
$count=0;
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC))
{
echo $row["open"] . "-" . $row["close"] ;
if ($count % 2 !=0 )
{
echo "<br/><br/>";
}
$count++;
}
}

Answer 2

try this:
$lines = 1;
if(mysql_num_rows($result2) > 0) {
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC)) {
echo $row["open"] . "-" . $row["close"];
echo (($lines%2 == 0)?"<br/><br/>":'');
$lines++;
}
} else {
echo "Error";
}

Answer 3

if(mysql_num_rows($result2) > 0){
$counter = 0;
while($row = mysql_fetch_array($result2, MYSQL_ASSOC)){
echo $row["open"] . "-" . $row["close"] . " ";
if(++$counter % 2 == 0){
echo "<br/><br/>";
$counter = 0;
}
}
}

Answer 4

if($result2) {
$printTimes = function($r) {echo $row["open"] . "-" . $row["close"];};
$newLine = false;
while ($row = mysql_fetch_assoc($result2))
{
$printTimes($row);
echo $newLine ? '<br /><br />' : ' ';
$newLine = !$newLine;
}
}

Answer 5

My version of code.
$sql2 = sprintf($rawsql2, mysql_real_escape_string($id));
$result2 = mysql_query($sql2);
if(mysql_num_rows($result2) > 0) {
while (true) {
$row1 = mysql_fetch_array($result2, MYSQL_ASSOC);
$row2 = mysql_fetch_array($result2, MYSQL_ASSOC);
if (!($row1 and $row2)) break;
echo $row1["open"] . "-" . $row1["close"] . " ";
echo $row2["open"] . "-" . $row2["close"] . "<br/><br/>";
}
} else {
echo "Error";
}

Answer 6

$i=1;
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC)) {
if ($i == 1) {
echo $row["open"] . "-" . $row["close"];
$i++;
} else {
echo $row["open"] . "-" . $row["close"] . "<br /><br />";
$i=1;
}

Answer 7

Output <br/><br/> only on every other iteration of the loop. (BTW, a <p> or <ul> or <div> would be more semantic.)
$counter = 0;
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC)) {
echo $row["open"] . "-" . $row["close"] . " ";
// Break line after every two items
$counter = ($counter + 1) % 2;
if ($counter == 0)
echo "<br/><br/>";
}

Answer 8

$sql2 = sprintf($rawsql2, mysql_real_escape_string($id));
$result2 = mysql_query($sql2);
/*These if & while statements decide whether or not the information should be displayed. If no results are returned from the query above then an alternative message is shown.*/
int row_count=mysql_num_rows($result2)
if(row_count > 0) {
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC)) {
row_count--;
echo $row["open"] . "-" . $row["close"] ;
if(row_count > 0 && ($row = mysql_fetch_array($result2, MYSQL_ASSOC)){
row_count--;
echo $row["open"] . "-" . $row["close"] ;
}
"<br/><br/>"
}
} else {
echo "Error";
}
should do it, u may need to catch if there is an odd number
