无法弄清楚简单的PHP / MySQL“问答”数据库中的错误

Question

I'm creating a simple questions DB, here are some details to start:

1st off, I am not using PDO - it's an old webapp, and this question is not about upgrading to PDO.

The DB

CREATE TABLE IF NOT EXISTS `questions` (
  `id` int(11) unsigned NOT NULL auto_increment,
  `question` varchar(255) NOT NULL,
  `userID` int(11) unsigned NOT NULL,
  `active` tinyint(1) NOT NULL default '1',
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;

Already inside the DB:

INSERT INTO `apl_questions` (`id`, `question`, `userID`, `active`) VALUES
(1, 'Do you have a dog?', 1, 1),
(2, 'Have you ever been arrested?', 1, 1),
(3, 'Pick yes or no...', 1, 1);

The PHP

$questionsResult = mysql_query("select * from questions where userID = 1 AND active = 1"); // Get all activated questions
    if(mysql_num_rows($questionsResult) > 0){
        $questions = mysql_fetch_assoc($questionsResult);
        var_dump($questions);
    }

The RESULT (of the PHP)

array(4) { ["id"]=> string(1) "1" ["question"]=> string(18) "Do you have a dog?" ["userID"]=> string(1) "1" ["active"]=> string(1) "1" } 

As you can see, this is only grabbing the first row - when it should be grabbing all rows since the userID and "active" column of all 3 rows are 1. Anyone see anything here that could be causing this problem? If I put the query into PHP MyAdmin, the query works correctly - so I have to assume at this point that it's the PHP... This is blowing my mind!

Thanks.

Answer 1

It seems mysql_fetch_assoc is row fetching, opposite to bulk fetching, which means it will fetch row per row inside a given array.

You have to loop over, for example in the php page:

while ($row = mysql_fetch_assoc($result)) {
   echo $row["userid"];
   echo $row["fullname"];
   echo $row["userstatus"];
}

rgds.

Answer 2

try:

$questionsResult = mysql_query("select * from questions where userID = 1 AND active = 1"); // //Get all activated questions
if(mysql_num_rows($questionsResult) > 0){
    while($questions = mysql_fetch_assoc($questionsResult)){
      var_dump($questions);
    }
 }
