i have a table which has id's and i want to select them in one query, then put them in an array...

i tried this:

$query = "SELECT GROUP_CONCAT(id) AS id_coll FROM table ORDER BY id DESC";

$result = mysql_query($query) or die ("no query");

while($row = mysql_fetch_assoc($result))
{    $cs = implode(", ", $row);

please help me with this, it doesn't matter if i need to change the query in any other way. i just need to have the id's in an array (1,2,3,......,19384)

 

thanks!

You don't need GROUP_CONCAT for this. Just select ID normally, then loop through the results and put them into an array.

[Psycho]

But, the reason you are having a problem is that you are using GROUP_CONCAT() but you don't have a GROUP BY to group on.

By row 256 you have probably hit the 1000 char size limit

thank you all for replying, could you please give me an example of selecting all the id's and put them into an array?

one which works, because i couldn't build one until now....

[Psycho]

$query = "SELECT id FROM table ORDER BY id DESC";

$result = mysql_query($query) or die ("no query");


$idsArray = array();

while($row = mysql_fetch_assoc($result))

{

    //Add each ID as a new element in the array

    $idsArray[] = $row['id'];

}


//Output the array to verify

echo "<pre>" . print_r($idsArray, 1) . "</pre>";
