Question

I have the code below and it’s working as it should however instead of echoing the results to the screen, I need to store the results in a php variable called $var. How would I go about doing that?

<?php
$sql = "SELECT id_member FROM smf_members WHERE FIND_IN_SET(24,additional_groups)";

$con = mysql_connect('localhost', 'sqluser', 'sqlpass');
if (!$con) {
   die('Could not connect: ' . mysql_error());
}

mysql_select_db("test_db");
$result = mysql_query($sql, $con);

while ($row = mysql_fetch_array($result)) {
   echo $row['id_member'];
}

mysql_close($con);
?>

Depending on what you want to achieve here is a few possible ways of doing this

$var = "";

while ($row = mysql_fetch_array($result)) {
  $var .= $row['id_member'] . "\n";
}

$var = array();

while ($row = mysql_fetch_array($result)) {
  $var[] = $row['id_member'];
}
