如何避免两次使用mysql_fetch_assoc

Question

Current page uses the:

$row_rsMyData = mysql_fetch_assoc (rsMyData);

As part of the mysql query created by Dreamweaver.

Later on in the page I'm using:

while ($row_rsMyData = mysql_fetch_assoc($rsMyData))

To fetch filenames from the database to add to an array.

The problem is the first fetch gets the first records in the row and doesn't leave the data there for the second fetch meaning the result is an array with one record missing.

What could I use instead of the second fetch or is there a way to reset before the second one takes place.

I have tried

mysql_data_seek()

But it doesn't seem to work for me.

Answer 1

The statement:

  $row_rsMyData = mysql_fetch_assoc (rsMyData);

does not reference an array-type variable. To gather multiple values into an array instead use:

  $row_rsMyData[] = mysql_fetch_assoc (rsMyData);

Answer 2

Besides the fact that you should not be using mysql_* functions, you can just check the current value of $row_rsMyData in the loop condition, use those data, and then fetch the next row at the end of the loop:

while($row_rsMyData)
{
    //do stuff with the data in $row_rsMyData

    //fetch the next row
    $row_rsMyData = mysql_fetch_assoc($rsMyData);
}

This of course assumes you can't do anything about removing the line generated by Dreamweaver.
