hi julian,
how about using this snip
 $result = mysql_query($sql)or die("fehler:".mysql_error());
 $num = mysql_num_rows($result);
 $erg = array();
 for ($i = 0; $i < $num; $i++) {
  $erg[$i] = array();
  $erg[$i] = mysql_fetch_object($result);
 }
i work with it, and its just fine. put it in a function or a class and 
you wont have to bother about processing the results anymore.

have fun.

and that works fine. Then later I need to access $result as a complete 
array again. Is there a way I can keep $result array intact and still 
take a couple values out beforehand. I can get it to work, by doing 
the select twice, but thats less than ideal.

Thanks enormously if you can help

http://us2.php.net/manual/en/function.mysql-data-seek.php 

This lets you set the internal row pointer of the mysql result. In your case
you would want mysql_data_seek($result,0).

Subject: doing SELECTS and keeping the array intact with php

Hi all,

this has been bugging me for some time now.

I want to do a mysql select
then using php

while ($a_row = mysql_fetch_array($result))
  {
do something to get a small portion of the data }


and that works fine. Then later I need to access $result as a complete array
again. Is there a way I can keep $result array intact and still take a
couple values out beforehand. I can get it to work, by doing the select
twice, but thats less than ideal.

Thanks enormously if you can help

More of a PHP question, but use reset($result); instead of a new query
