PHP DELETE immediately after select
- by teehoo
I have a PHP server script that SELECTs some data from a MySQL database.
As soon as I have the result from mysql_query and mysql_fetch_assoc stored in my own local variables, I want to delete the row I just selected.
The problem with this approach is that it seems that PHP has done pass-by-reference to my local variables instead of pass-by-value, and my local variables become undefined after the delete command.
Is there anyway to get around this? Here is my code:
$query="SELECT id, peerID, name FROM names WHERE peer = $userID AND docID = '$docID' AND seqNo = $nid";
$result = mysql_query($query);
if (!$result)
self::logError("FAIL:1 getUsersNamesUpdate() query: ".$query."\n");
if (mysql_num_rows($result) == 0)
return array();
$row = mysql_fetch_assoc($result);
$result = array();
$result["id"] = $row["id"];
$result["peerID"] = $row["peerID"];
$result["name"] = $row["name"];
$query="DELETE FROM names WHERE id = $result[id];";
$result = mysql_query($query);
if (!$result)
self::logError("FAIL:2 getUsersNamesUpdate() query: ".$query."\n");
return $result;
