在PDO中输出选择查询

Question

I'm used to using BindParam() and since this is a SELECT query Param's are not related. Basically I'm trying to make a notification system that will check the database and if any of the rows' status is '0' then it would output all the rows information.

I have the following columns: id, api, request, apikey, apiemail, keyauth, ip, dateandtime, status .

How would I make PDO put all the information it gathers from all rows with status='0' and put them into usable variables like: $id, $api, $request ? Of course there could be more then one row with status='0' so maybe have the variables arrays and output like $id[0], $id[1] etc

PDO:

<?php

include('/cdn/global/db.php');

$opt = array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION );
$dsn = "mysql:host=$host;dbname=$dbname";

$DBH = new PDO($dsn, $username, $password, $opt);
$DBH->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$DBH->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

$STH = $DBH->prepare("SELECT id, api, request, apikey, apiemail, keyauth, ip, dateandtime, status FROM apirequests WHERE status = 0");

$STH->execute();

echo "<p>The link is now in Queue, An admin will check the link soon!</p>";


# close the connection  
$DBH = null;

Answer 1

You can fetch them as objects(Also order by a field if you want the results in a specific order):

$STH = $DBH->prepare("SELECT id, api, request, apikey, apiemail, keyauth, ip, dateandtime, status FROM apirequests WHERE status = 0 ORDER BY id");
$STH->execute();
if($STH->rowCount()){
 while($row = $STH->fetch(PDO::FETCH_OBJ)){
  #Perform whatever operation you need on a single row
  echo "$row->id, $row->api, $row->request, $row->apikey, $row->apiemail\n";
 }
}

put them into usable variables like: $id, $api, $request etc

There is no point in doing that. $row['id'] is no less usable but WAY more flexible. Although you can use extract() function to assign array members to corresponding variables.

of course there could be more then one row with status='0' so maybe have the variables arrays and output like $id[0], $id[1] etc

This would make even less sense and nobody is doing it this way. Anyways, PDO won't make such variables for you. Instead, array of rows have to be used, like shown in other answers.

Answer 3

$value = 0;     
$STH = $DBH->prepare("SELECT id, api, request, apikey, apiemail, keyauth, ip, dateandtime, status FROM apirequests WHERE status = ?");
$STH->execute(array($value));
 $variable[] = $STH->fetchAll(PDO::FETCH_ASSOC);
