MySQL consequent numbers - php

Question

I use this function in my while loop to track the numbers of results.
$lvarcontributor = "SELECT * FROM dD_Contributors WHERE idAlbum = '".$idAlbum."' ORDER BY idContributor ASC";
$lvarresult=mysql_query($lvarcontributor);
$var = 0;
while ($lvarrow = mysql_fetch_array($lvarresult))
{
$var++;
//STUFF HERE...
}
How do I know the last result?
I need to know when $var++ is arrived at the last result. such as
If($var == "LAST RESULT") {
//do this
}
THANKS!

Answer 1

Use mysql_num_rows function - http://php.net/manual/en/function.mysql-num-rows.php

Answer 2

This function may be helpfull:
mysql_num_rows
if (($var + 1) == musql_num_rows($result))
{
//this is the last row
}

Answer 3

if( $var == mysql_num_rows($lvarresult) - 1 ) {
// this is the last row, do your thing
}

Answer 4

Maybe you want to check the mysql_num_rows function.
If you want to access only the last result, you should review your SQL query to fetch only this one (try messing with ORDER BY and LIMIT).
If you want to fetch every rows, but have a special treatment for the last result, then you can dut as follow:
$nextRow = mysql_fetch_array($lvarresult);
while ($nextRow)
{
$currentRow = $nextRow;
if($nextRow = mysql_fetch_array($lvarresult)) {
//Not the last row, data in $currentRow
}
else {
//Last row, data in $currentRow
}
}
