Display the result table for 2 sql queries in php - php

Question

I'm writing a php file, and I want to show two tables by executing 2 seperate queries, and store them in $result and $result_bike. However, when I try to open the html page for this action form, it only shows the table for the first query, and gives the error " Commands out of sync; you can't run this command now" at the place of the second table.
Also, I don't want to combine these two tables, as they show entirely different information and I want to insert some text explaining each table.
I think there might have something to do with not able to print two tables for php (which I doubt)? What change should I make?
Thank you in advance for the help!
$result = mysql_query("CALL CrashTypeRate_Ped('$city')", $conn);
if (!$result){
echo "Fail to retrieve result for pedestrian crashes!\n";
print mysql_error();
} else {
echo "<table border=1>\n";
echo "<tr><td>CrashType</td><td>Count</td><td>TotalCount</td></tr>\n";
while ($myrow = mysql_fetch_array($result)) {
printf("<tr><td>%s</td><td>%s</td><td>%s</td></tr>\n", $myrow["crash_type"], $myrow["type_count"], $myrow["total_count"]);
}
echo "</table>\n";
}
$result_bike = mysql_query("CALL CrashTypeRate_Bike('$city')", $conn);
if (!$result_bike) {
echo "Fail to retrieve result for bike crashes!\n";
print mysql_error();
} else {
echo "got here!!!!!!";
echo "<table border=1>\n";
echo "<tr><td>CrashType</td><td>Count</td><td>TotalCount</td></tr>\n";
while ($myrow = mysql_fetch_array($result_bike)) {
printf("<tr><td>%s</td><td>%s</td><td>%s</td></tr>\n", $myrow["crash_type"], $myrow["type_count"], $myrow["total_count"]);
}
echo "</table>\n";
}

Here is from PHP Documentation user comments. Hope this helps
Link to PHP Documentation
When calling multiple stored procedures, you can run into the following error: "Commands out of sync; you can't run this command now".
This can happen even when using the close() function on the result object between calls.
To fix the problem, remember to call the next_result() function on the mysqli object after each stored procedure call. See example below:
<?php
// New Connection
$db = new mysqli('localhost','user','pass','database');
// Check for errors
if(mysqli_connect_errno()){
echo mysqli_connect_error();
}
// 1st Query
$result = $db->query("call getUsers()");
if($result){
// Cycle through results
while ($row = $result->fetch_object()){
$user_arr[] = $row;
}
// Free result set
$result->close();
$db->next_result();
}
// 2nd Query
$result = $db->query("call getGroups()");
if($result){
// Cycle through results
while ($row = $result->fetch_object()){
$group_arr[] = $row;
}
// Free result set
$result->close();
$db->next_result();
}
else echo($db->error);
// Close connection
$db->close();
?>
