如何将多行MySQL数据库放入多维数组（PHP）？

Question

I am working on a system where a query checks the database for records matching multiple ids and puts each row into it's own array. So far I only got the last row to echo out in it's own array. Here is the query code:

$query = "SELECT * FROM messages WHERE senderid IN ($senderids) ORDER BY messageid DESC";
$resource = mysql_query($query, $database);
$result = mysql_fetch_array($resource);
foreach($result as $result1)
    {
    print_r($result1);
    echo '<br>';
    }

This is what echos in the browser:

2
2
1
1
TEST MSG 2
TEST MSG 2
2014_09_13_01:29:59
2014_09_13_01:29:59

This is what should echo:

Array ([messageid] => 1 [senderid] => 1 [message] => test message [date] => 2014_09_13_01:01:09)
Array ([messageid] => 2 [senderid] => 1 [message] => TEST MSG 2 [date] => 2014_09_13_01:29:59)

How would I go about fixing this issue?

mysql_fetch_array does not return the whole result set, just the row at the current cursor. Your code isn't moving the mysql cursor; to do that, your code should be:

$resource = mysql_query($query, $database);
while($row = mysql_fetch_array($resource)){
  print_r($row);
  echo '<br />';
}

Also, for the desired output you posted, you should use mysql_fetch_assoc instead as it will be a hash with column names instead of an indexed array
