Php mysql query displaying data it shouldn't - php

Question

I've got a project that involves getting flight information from a database.
I want the results to look like:
01 Nov 2017 - Eastern Airways 7601
Departing from Southampton, Eastleigh (SOU) at 0840
However my code seems to bring up the below with a mysterious live of nonsense as per below
01 Nov 2017 - Eastern Airways 7601
Departing from , () at 084001 Nov 2017 - 7601 //this line I don't want
Departing from Southampton, Eastleigh (SOU) at 0840
$link = mysqli_connect('xxx', 'xxx', 'xxx', 'xxx' );
foreach ($flights as $b) {
$query = "SELECT * FROM `airlines` WHERE `iatacode` = '$airline' LIMIT 0 , 30;";
$query .= "SELECT * FROM `airports` WHERE `Airport Code` = '$depdest' LIMIT 0 , 30;";
/* Execute queries */
if (mysqli_multi_query($link, $query)) {
do {
/* store first result set */
if ($result = mysqli_store_result($link)) {
while ($row = mysqli_fetch_array($result))
/* print results */
{
$date=date_create($depdate);
echo "<b>" . date_format($date,"d M Y"). " - ". $row['airlinename']." ".$flightno. "</b><br/>";
echo "Departing from " .$row['City Name'].", ".$row['Airport Name']." (".$row['Airport Code'].") at " . $deptime;
}
mysqli_free_result($result);
}
} while (mysqli_next_result($link));
}
Can anyone see what I'm doing wrong?
Data base tables are as below
table 1 - Name "airports"
Airport ID City name Airport Code Airport Name Country name Country Abbrev. World Area Code
1, 108 Mile Ranch, ZMH , 108 Mile Ranch , Canada, CA, 906,
2, Aachen, AAH Aachen/Merzbruck, Germany, DE, 429,
3, Aachen, ZIU, Railway, Germany, DE, 429,
4, Aalborg, AAL, Aalborg, Denmark, DK, 419,
etc
table 2 - Name "airlines"
airline id, Iata, Airline Name
1, 0A, Amber Air,
2, 0B, Blue Air,
3, 0C, IBL Aviation,
etc
Thanks!

Answer 1

If I was to guess, I would say that there is a problem with the $b variable.
It seems your output is being written twice: the value "084001" in the middle of the second line looks to be the 0840 flight time from one entry, and then immediately starting the next entry as the date.
I would guess that the foreach is looping twice, instead of once, causing two outputs.
Could you do an output of the $b variable?
echo "<pre>";
print_r($b);
echo "</pre>";
