easier way to get counter from while loop?

Question

I have the following:

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

    echo($counter2 . $row[\'foo\']);
}
<         


        

Answer 1

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']);
}

Answer 2

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'];
}
