PHP Loop through results

Question

I am trying to loop through my database and check to see if the user already exists in another table. If they do then I want to increment a value, if they don't then I want to add the user.

When I run the code below it happily loops through all the results:

 <?php $servername = "p:10*********"; $username = "*******"; $password = "*******"; $dbname = "******"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT * FROM payroll WHERE user != ' ' "; $result = $conn->query($sql); if ($result->num_rows > 0) { echo $result->num_rows; while($row = $result->fetch_assoc()) { $user= $row['user']; $time= $row['time']; $id= $row['id']; echo $id; echo $user; } } else { echo "0 results"; } $conn->close(); ?> 

However when I add in the SQL to check to see if they exist in the other table the loop no longer functions correctly and echos the same user each time.

 <?php $servername = "*******"; $username = "******"; $password = "********"; $dbname = "*****"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT * FROM payroll WHERE user != ' ' "; $result = $conn->query($sql); if ($result->num_rows > 0) { echo $result->num_rows; while($row = $result->fetch_assoc()) { $user= $row['user']; $time= $row['time']; $id= $row['id']; echo $id; echo $user; $sql = "SELECT * FROM smsreport WHERE user = '$user'"; $result = $conn->query($sql); if ($result->num_rows > 0) { echo "found"; } else { echo "USER NOT FOUND"; } } } else { echo "0 results"; } $conn->close(); ?> 

Any help much appreciated.

In the open eye: Rename the inside $result variable. It is over writting the first $result .

It could be the problem. Not tested though.
