PHP SQL server query - php

Question

I'm running a query to get the contents for a web slider.
$serverName = "livedata";
$connectionInfo = array( "Database"=>"DB", "UID"=>"User", "PWD"=>"PWD" );
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT Sliders.DisplayFrom, Sliders.DisplayUntil, Sliders.Sort, Sliders.Image, Sliders.Link, Sliders.Target FROM Sliders WHERE (((Sliders.DisplayFrom)<GetDate()) AND ((Sliders.DisplayUntil)>getdate())) ORDER BY Sliders.sort;";
$stmt = sqlsrv_query( $conn, $sql);
if( $stmt === false ) {
die( print_r( sqlsrv_errors(), true));
}
$result = sqlsrv_query($conn, $sql);
$maxx = 0;
while($row = sqlsrv_fetch_array($result)) {
$maxx++;
}
while($row = sqlsrv_fetch_array($result)) {
echo “<br>” . $row[‘Image’];
}
The second loop does not output any results. why? Is it because $row is already at the end? If so, how do I move first like in ASP without having to create $result2 and $row2, 3, 4, 5, ...
Would it be better to use for loops like in vb.net?
for ($i = 0; $i <= $maxx; $i++){
}
But then How do I specify the output if I have no $row?
and if I only wanted to output the first row like I do in vb.net, how would I write the following in PHP?
dsqueryResults.tables(0).rows(0).item("Image");
would I still use a while loop and have a variable inside the loop to hold the row number and only output if row = 0?
$WhichRow = 0;
while($row2 = sqlsrv_fetch_array($result2)) {
if ($whichRow == 0){
echo “<br>” . $row2[‘Image’];
}
$WhichRow++;
}

Use the $max++ counter inside the while loop if you really want to use that for other purposes.
If you just want a count then run a count query on MySQL or do an array count of returned result.
If you just want to print 1 row use
LIMIT 0,1
at the end of your query as there's no point in fetching all rows and waste resources.
Based on additional comments you can try this to get your current row number.
$result = sqlsrv_query($conn, $sql);
$rownumber = 0;
while($row = sqlsrv_fetch_array($result)) {
$rownumber = $rownumber + 1;//Your current row number.
echo “<br>” . $row[‘Image’];
}
