The following function to read all data out of a mysql-resultset, is may be faster than Rafaels solution:



<?

function mysql_fetch_all($result) {

   while($row=mysql_fetch_array($result)) {

       $return[] = $row;

   }

   return $return;

}

?>

It is probably worth pointing out that the array elements will actually be of type string, OR NULL if the field is null in the database.



Thus, either use a double equal comparison to look for empty or null



Or, use a triple equal comparison to be able to distinguish the two cases



e.g.



if ($field === '') echo "Empty, not NULL\n";



if ($field === NULL) echo "NULL\n";



if ($field == '') echo "Empty or NULL\n";

to print an array, simply use print_r(array name)



like this:

    $myrow = mysql_fetch_row($result);

echo "<pre>";

print_r($myrow);

echo "</pre>";



this will output the array in a readable form, with the index, too. Don't forget the 'pre' tags or the output will be on a single line.

Maybe worth pointing out that all the fields returned by this (and other?) calls are returned with type string. This had me puzzled for quite some time.

You could also use this language construct with mysql_fetch_row:



while (list($first, $second) = mysql_fetch_row($resource)) {

[...]

}

you can also use mysql_fetch_row() like this if you want to display inumerable results the same way:



#connect to the server and select db

mysql_connect("host","username","pass");

mysql_select_db("dbname");



#query the db

$query = "SELECT * FROM table";

$result = mysql_query($query)

or die(mysql_error());



#display results

while($i = mysql_fetch_row($result)) {

echo $i[0];

echo $i[1];

.....

}



and so forth...
