 Hello All,

 I am trying to use the @ symbol to suppress errors returned by a
 mysql_query call.  This doesn't seem to be working as I get an new page
with
 the error in it in my browser.  Any help with this would be greatly
 appreciated.

 Here is a snippet of the code I am using

   $query = select user_id from users where username='$username';
   $query_db = @mysql_query($query, $db_connection);
   $row = @mysql_fetch_array($query_db);
   if($row) {
  $message[] = That username is already taken. Please select
 another.;
   } else {

 Thanks,
 Preston

RE: [PHP] suppressing errors

[Preston Wade]

The error is one from mysql stating that I am trying to add a duplicate
entry.  I would rather handle this in my code hence the following lines in
my code.

if($row) {
  $message[] = That username is already taken. Please select
another.;
  } else {

Thanks for the response.

Thanks,
Preston

 $query = select user_id from users where username='$username';
 $query_db = @mysql_query($query, $db_connection);
 $row = @mysql_fetch_array($query_db);
 if($row) {
$message[] = That username is already taken. Please select
   another.;
 } else {

 my code.

That error message wouldn't come from any of the lines above. You're not
INSERTing anything, just SELECTing. Are you sure there isn't another
mysql_query() somewhere else without an @ in front of it??

Re: [PHP] suppressing errors with @

[Uri Even-Chen]

Thanks! I also think it might be a bug. I reported it as a bug report.

Uri.

 It does seem to be a disagreement with the manual:
 
http://www.php.net/manual/en/language.operators.errorcontrol.php
 
 There it says that you can stick  before a variable name.
