saving strings into an array - php

Question

I've got a query which finds the top 10 most loaned books in my loan table, however i want to store these ten values into a single array so that I can then use the array again. Here is the code I have so far... Thanks for any help in advance!
//select a database to work with
$selected = mysql_select_db("ds2",$dbhandle)
or die("Could not select examples");
//execute the SQL query and return records
$result = mysql_query("SELECT book.title, book.book_id, count(book.book_id) AS count_book_id, loan.book_id FROM book
INNER JOIN loan ON book.book_id = loan.book_id
GROUP BY book.book_id ASC
ORDER BY count(book.book_id) DESC");
$titles = array();
while($row = mysql_fetch_array($result))
{
echo $row['title'];
echo "<br>";
}
echo "<br><br>";
for($index = 1; $index <= 10; $index++)
{
array_push($titles,$result[$row]);
print_r($titles);
echo "<br>";
}

Answer 1

Rather than echo $row['title'] You can use below code to store them into an array
$titles[] = $row['title'];
Use array notion to access them later.
$titles[0]; // 1st item
$titles[1]; //2nd item
You can even use a foreach loop to loop through all the items.
foreach($titles[] as $title)
echo $title;
Below will allow you to get a comma separated string(Just for your information if you need it)
$comma_separated_titles = implode(",", $titles);

Answer 2

Try,
while($row = mysql_fetch_array($result))
{
echo $row['title'];
$arr[] = $row['title']; //Store in an array
echo "<br>";
}
echo "<br><br>";
//Since you need only 10 values, else this for loop is not required.
for($index = 1; $index <= 10; $index++)
$titles[] = $arr[$index]['title'];
unset($arr); //unset the original array if you don't need it anymore.
print_r($titles); //Print top 10 values
echo "<br>";

Answer 3

You should fill your array in the loop, not after it in a separate loop:
$count = 0;
while($row = mysql_fetch_array($result))
{
echo $row['title'];
echo "<br>";
if ($count < 10)
{
array_push($titles, $row);
}
$count++;
}
