Eperimenting PHP just for fun, But As being newbie, I'm unable to understand curcial parts of PHP....Please help me to sort out this problem which I'm explaining by example :
Suppose
$sql = "SELECT id, text,uid FROM feeds WHERE uid='".$ud."' LIMIT 10";
$items = mysql_query($sql);
echo mysql_error();
if (#mysql_num_rows($items) > 0)
{
while ($item = mysql_fetch_array($items))
{
$feed = $item[1];
$nick = getnick($item[2]);
}
}
So I want to display like this :
3 Records with uid details...
jay,vicky, sumair and 17 others like this.
Please help me to get output of something like this !!
Thanks !!

Answer 1

I can't stretch this enougth,
DO NOT USE MYSQL_* API anymore. [Read this]
It is VULNERABLE, mysqli_* functions are just as similar very little difference.
And You already are doing the things required for that output mysql_num_rows() already gives the number of total result. So:
if (mysql_num_rows($items) > 0)
{
$count = mysql_num_rows($items);
echo $count." Records with uid details..."; //Display the count of records
$threeNameHolder = array; // Hold the first three names on this
while ($item = mysql_fetch_array($items))
{
$feed = $item[1];
$nick = getnick($item[2]);
if(count($threeNameHolder) < 3) {
$threeNameHolder[] = $nick;
} else break; // End the loop here
}
//Now display the name
echo implode(",", $threeNameHolder). " and ".($count - 3)." others like this.";
}
Safer and MYSQLi Version
if (mysqli_num_rows($items) > 0)
{
$count = mysqli_num_rows($items);
echo $count." Records with uid details..."; //Display the count of records
$threeNameHolder = array; // Hold the first three names on this
while ($item = mysqli_fetch_array($items))
{
$feed = $item[1];
$nick = getnick($item[2]);
if(count($threeNameHolder) < 3) {
$threeNameHolder[] = $nick;
} else break; // End the loop here
}
//Now display the name
echo implode(",", $threeNameHolder). " and ".($count - 3)." others like this.";
}

To understand the basics fundaments, I really recommend the official documentation PHP
http://www.php.net/manual/en/ref.mysql.php
A simple sample to execute a query and display the output:
$query = mysql_query("SELECT a, b FROM table_name WHERE c='".$something."' LIMIT 10");
$num_rows = mysql_num_rows($query);
$test = array(); // create a empty array
/* while there is result */
while ($item = mysql_fetch_array($items)){
$columnA = $item[0];// first column (a)
$columnB = $item[1]); // second column (b)
$test[] = $columnB; // push_back a item on array
}
echo $num_rows. " Records with **" . $something . "**...";
echo implode($test, ", ") . "and some text";
