Array seems to stop after 7 items - php

Question

I have this odd behavior from a table I am drawing. When I add more than 7 entries to the DB for the table to draw, it seems like it crashes and doesn't draw anything. 7 or less and it works just fine.
I have no idea why it would be doing this???
$strSQL = "
SELECT u.username playername
, IFNULL(a.avatar,'default.jpg') playeravatar
FROM add_tournament_repeat_guests p
JOIN nfojm_users u
ON p.guestID = u.id
LEFT
JOIN nfojm_comprofiler a
ON u.id = a.user_id
WHERE p.parent_id = $tournID
";
$query = mysqli_query($con, $strSQL);
while ($row = mysqli_fetch_array($query)) {
if (!in_array($row["playername"], $playernames)) {
$i=0;
$indexes[$row["playername"]] = 0;
$playernames[] = $row["playername"];
} else {
$indexes[$row["playername"]]++;
$i = $indexes[$row["playername"]];
}
if (!in_array($row["playeravatar"], $playeravatars)) {
$i=0;
$indexes[$row["playeravatar"]] = 0;
$playeravatars[] = $row["playeravatar"];
} else {
$indexes[$row["playeravatar"]]++;
$i = $indexes[$row["playeravatar"]];
}
}
print('<table class="block" style="border:2px solid #999999; width:175px; background-color: aliceblue; margin-top:-7px"><thead><tr><th style="color:white; background-color:#444444; height:35px;"> <h2>Leaderboard</h2> </th></tr></thead><tbody>');
foreach (array_combine($playeravatars, $playernames) as $playeravatar => $playername) {
print("<tr><td style='padding-left:8px;' class='block'><h4><img src='http://www.arcadeicons.com/images/comprofiler/" . $playeravatar . "' height='35' width='35' style='border-radius:50%'> " . $playername . "</h4></td></tr>");
}

Answer 1

$playeravatars and $playernames have different lengths, that's why array_combine() returns FALSE instead of combined array as you expect (php.net/array_combine)
2 users with different names and without avatars will generate 2 rows in $playernames, but only 1 row in $playeravatars -- that is the reason of length mismatching
You may write your code simplier:
echo '<table class="block" style="border:2px solid #999999; width:175px; background-color: aliceblue; margin-top:-7px"><thead><tr><th style="color:white; background-color:#444444; height:35px;"> <h2>Leaderboard</h2> </th></tr></thead><tbody>');
while ($row = mysqli_fetch_array($query)) {
echo "<tr><td style='padding-left:8px;' class='block'><h4><img src='http://www.arcadeicons.com/images/comprofiler/" . $row['playeravatar'] . "' height='35' width='35' style='border-radius:50%'> " . $row['playername'] . "</h4></td></tr>";
}
