QUERY works in phpyMyAdmin but not in PHP - php

Question

My Query don't work in PHP but when I test it in my database it works well.
Code:
<?php
//Database connectie
$link = mysqli_connect("*", "*", "*", "*") or die("Error ". mysqli_error($link));
ini_set('memory_limit', '1024M'); // or you could use 1G
//Query //
$query = "SET SQL_BIG_SELECTS = 1;";
$query = "SELECT * FROM datakram, datakram2, datakram3, datakram4 WHERE datakram.ISIN = datakram2.ISIN AND datakram2.ISIN = datakram3.ISIN AND datakram3.ISIN = datakram4.ISIN";
$result = mysqli_query($link, $query);
?>
<table>
<thead>
<tr class="warning">
<th>Naam</th>
<th>ISIN</th>
<th>Jaar</th>
<th>Closely Held Shares</th>
<th>Outstanding Sahres</th>
<th>Market capitalistion</th>
</tr>
</thead>
<tbody>
<?php
while($row = mysqli_fetch_assoc($result))
{
?>
<tr>
<td><?php echo $row['company-name'];?></td>
<td><?php echo $row['ISIN'];?></td>
<td>2017</td>
<td><?php echo $row['2017'];?></td>
<td><?php echo $row['2017-shares'];?></td>
<td><?php echo $row['2017-market'];?></td>
</tr>
<?php
}
?>
Knows somebody why? I have tried: $result = mysqli_multi_query($link, $query); But that didn't work.
I have fix it, don't tell me how ;) but it works. Here if somebody need it:
//Database connectie
$link = mysqli_connect("*", "*", "*", "*") or die("Error ". mysqli_error($link));
ini_set('memory_limit', '1024M'); // or you could use 1G
//Query //
$query = "SET SQL_BIG_SELECTS = 1;";
$query .= "SELECT * FROM datakram, datakram2, datakram3, datakram4 WHERE datakram.ISIN = datakram2.ISIN AND datakram2.ISIN = datakram3.ISIN AND datakram3.ISIN = datakram4.ISIN";
if (mysqli_multi_query($link, $query)) {
do {
?>
<table>
<thead>
<tr class="warning">
<th>Naam</th>
<th>ISIN</th>
<th>Jaar</th>
<th>Closely Held Shares</th>
<th>Outstanding Sahres</th>
<th>Market capitalistion</th>
</tr>
</thead>
<tbody>
<?php
if ($result = mysqli_store_result($link)) {
while($row = mysqli_fetch_assoc($result))
{
?>
<tr>
<td><?php echo $row['company-name'];?></td>
<td><?php echo $row['ISIN'];?></td>
<td>2017</td>
<td><?php echo $row['2017'];?></td>
<td><?php echo $row['2017-shares'];?></td>
<td><?php echo $row['2017-market'];?></td>
</tr>
<?php
}
}
} while (mysqli_next_result($link));
}
?>
