Inner nested while loop is false on second iteration - php

Question

The code below creates html table data.
Row 1 is correct and returns column1 with $row['LNAME'] and then column2 with ALL of the $row1['NAME'] results (there are four).
Row 2 and onwards echo only column1 and an empty cell in column2.
while ($row = $sql->fetch_assoc()){
echo "<tr>";
echo "<td>";
echo $row['LNAME'];
echo "</td>";
echo "<td>";
while($row1 = $sql1->fetch_assoc()){
echo $row1['NAME'] . "<br>";
}
echo "</td>";
echo "</tr>";
}
It would seem that after the inner loop has completed it evaluates as false in future iterations of the outer loop where I would like it to evaluate as true.
What should I change so that the inner loop does not evaluate as false until the outer loop does?

Answer 1

This is because you're at the end of $sql1. You can seek to the beginning of it again, but my preference is to separate pulling the data from the DB and the iterations, so I'd write it like this (using your code as the starting point):
$lname = array();
while($row = $sql->fetch_assoc()){
$lname[] = $row;
}
$name = array();
while($row1 = $sql1->fetch_assoc()){
$name[] = $row1;
}
foreach($lname as $lvalue) {
echo "<tr>";
echo "<td>";
echo $lvalue;
echo "</td>";
echo "<td>";
foreach($name as $value) {
echo $value . "<br>";
}
echo "</td>";
echo "</tr>";
}

Answer 2

you will need to use mysql_data_seek($rs, 0) to reset your result pointer at the first row. this is under the assumption that mysql is hidden behind your object. for mysqli use mysqli_data_seek respectively
