PHP Error: mysql_fetch_array() expects parameter 1 to be resource, boolean given

I'm very confused with this error, it shows when I try to return a result from the DB that doesn't exist ... I tried mysql_num_rows() but it returns the same error but instead of mysql_fetch_assoc expects ... it says mysql_num_rows() expects ...

I set error_reporting(0) to avoid showing this error, but I'm not satisfied with this solution ...



Here's the proper way to do things:

$sql = 'some query...';
$result = mysql_query($q);

if (! $result){
   throw new My_Db_Exception('Database error: ' . mysql_error());

while($row = mysql_fetch_assoc($result)){
  //handle rows.

Note the check on (! $result) -- if your $result is a boolean, it's certainly false, and it means there was a database error, meaning your query was probably bad.

mysql_real_escape_string just takes a string for an argument. That's it.

$string = mysql_real_escape_string('string')

If you want to specify the link identifier, it is the optional second argument:

$string = mysql_real_escape_string('string', $dbc)

Sometimes that warning is that if the result of the query within while returns no value, that is, such as when no records on table.

What I mean is that in some cases your code and your application is correct and yet the warning appears.

to hide the warning uses the character @.


while(@$rs = mysql_fetch_array($sql)) {

Probably mysql_query() failed. In this case it returns false. Use mysql_error() to find out, what happens.

yo need create the user "pma" in mysql or change this lines(user and password for mysql):

/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma'; 
$cfg['Servers'][$i]['controlpass'] = '';

Linux: /etc/phpmyadmin/
