mysql fetch array individual echo php - php

Question

need to get row content from a mysql select statement. Currently starting at high id and desc. Need to take the highest id and get it, and the next 15 in line, and need to store them as variables. Here is an example:
$servername = "localhost";
$username = "_p";
$password = "1";
$dbname = "w";
mysql_connect("localhost", "p", "s") or die(mysql_error());
mysql_select_db("p") or die(mysql_error());
$highest_id = mysql_result(mysql_query("SELECT MAX(id) FROM NE2"), 0);
$result = mysql_query("SELECT content, id FROM NE2 order by ID desc LIMIT 15 ");
while($row[0] = mysql_fetch_array($result)){
echo $row[0]['content'];

Answer 1

You could do it with one query and access the top 16 ids, (the max id and the 15 next ids)
$servername = "localhost";
$username = "_p";
$password = "1s";
$dbname = "wc";
mysql_connect($servername, $username, $dbname) or die(mysql_error());
mysql_select_db("we_ppp") or die(mysql_error());
// Let's get the 16 first highest id's and their content
// Why 16 ? We want the highest and the 15 next
$result = mysql_query("SELECT content, id FROM SEARCH2 order by ID desc LIMIT 0, 16");
// Now it's easied to handle if we just stack the result in a big array
$data_array = array();
while($row = mysql_fetch_array($result)) {
$data_array[] = $row;
}
// Now we have $data_array[0] to $data_array[15] (the 16th row) each one containing
// an associative array resulting from the mysql_fetch_assoc().
// Now if I want the highest id :
$highest_id = $data_array[0]['id'];
$highest_content = $data_array[0]['content'];
// And the next 15 are
for($i = 1; $i < 16; $i++) { // We start at the second line until the 16th (numer 15)
echo $highest[$i]['id'];
echo $highest[$i]['content'];
}
// Now you do whatever you want with $highest and the next ones

Answer 2

use it like this
$result = mysql_query("SELECT content, id FROM S_ENGINE2 order by ID desc LIMIT 15");
if (mysql_num_rows($result) > 0)
{
while($row = mysql_fetch_array($result))
{
echo $row['content']."<br>";
}
}
may this will help you

Answer 3

The while loop executes row by row, and at an instance you could have only one row (just like array index), so do like
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
echo $row["id"];
echo $row["contetnt"]);
}
