You are confusing the PHP and MySQL.
<?php
$count = count($categoriesIN);
for ($ii = 0; $ii < $count; ++$ii) {
$sql = "INSERT INTO temp (example) VALUES ('" .
mysql_real_escape_string($categoriesIN[$ii]) . "')";
$result = mysql_query($sql, $db);
}
?>
MySQL also has an alternative syntax that you can use to do this in a
single statement:
<?php
$count = count($categoriesIN);
if ($count > 0) {
$sql = "INSERT INTO temp (example) VALUES ";
for ($ii = 0; $ii < $count; ++$ii) {
if ($ii > 0) $sql .= ', ';
$sql .= "('" . mysql_real_escape_string($categoriesIN[$ii]) . "')";
}
}
$result = mysql_query($sql, $db);
?>
