easier way to get counter from while loop?

I have the following:

$counter = 1;   
while($row= mysql_fetch_assoc($result)) {
    $counter2 = $counter++;

    开发者_开发百科echo($counter2 . $row['foo']);
}

Is there an easier way to get 1,2,3 etc for each result or is this the best way?

Thanks

You don't need $counter2. $counter++ is fine. You can even do it on the same line as the echo if you use preincrement instead of postincrement.

$counter = 0;   
while($row= mysql_fetch_assoc($result)) {
    echo(++$counter . $row['foo']);
}

I know it's not exactly what you have asked for - but why don't you simply use a for-loop instead of while?

for ($i = 0; $row = mysql_fetch_assoc($result); ++$i) {
    echo $i . $row['foo'];
}
