Only Displaying one row Mysql - php

Question

I want this data to display all the results, in the query I get 129 results. But when I display it on the page I only get one row. I have used very similar code to get multiple results before, so I know it`s something simple, but I just can't get it. Any thoughts would be greatly appreciated!
<?php
$sql = "SELECT SUM(datamb) AS value_sum FROM maindata GROUP BY phonenumber";
$sql1 = "select dataplan as currentplan from maindata GROUP BY phonenumber";
$sql2 = "SELECT DISTINCT phonenumber AS value_sum1 FROM maindata";
$result = mysql_query($sql);
if (!$result) {
echo "Could not successfully run query ($sql) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
$result1 = mysql_query($sql2);
if (!$result1) {
echo "Could not successfully run query ($sql1) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result1) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
$result2 = mysql_query($sql2);
if (!$result2) {
echo "Could not successfully run query ($sql2) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result2) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
while ($row = mysql_fetch_assoc($result)){
echo "<TABLE id='display'>";
echo "<td><b>Data Usage This Period: ". ROUND ($row["value_sum"],2) . "MB</b></td> ";
}
while ($row1 = mysql_fetch_assoc($result1)){
echo "<TABLE id='display'>";
echo "<td><b>Data Plan: ". $row1["currentplan"] . "</b></td> ";
}
while ($row2 = mysql_fetch_assoc($result2)){
echo "<TABLE id='display'>";
echo "<td><b>Phone Number: ". $row2["value_sum1"] . "</b></td> ";
}
?>
Updated based on suggestions - Very helpful thank you, I am very close, all values are correct but I can not get them in the same table, thoughts?

Answer 1

TRY To use ,
Loop in you code eg.
$result1 = mysql_query("SELECT DISTINCT phonenumber AS value_sum1 FROM maindata");
echo '<table>';
echo '<tr>';
echo '<th>id</th>';
echo '</tr>';
while($record = mysql_fetch_assoc($result))
{
echo '<tr>';
foreach ($record as $val)
{
echo '<td>'.$val.'</td>';
}
echo '</tr>';
}
echo '</table>';

Add
"LIMIT 0, 1" at the end of query
or
edit query like "select TOP 1 from....."
