Konvertieren in mysql_connect zu PDO

Question

Hallo Ich habe diesen Code funktioniert, aber ich muss den Code konvertieren, um als PDO zu arbeiten. Ich habe so viele Variationen versucht, aber nicht gearbeitet. Ich habe $ conn als Verbindung. Vielen Dank im Voraus.

 $projectrfpid = $_GET['projectrfpid']; 
     $allRecords = mysql_query('SELECT * FROM projectscostbreakdown WHERE projectscostbreakdown_projectid='.$projectrfpid.' AND projectscostbreakdown_deleted=1 ORDER BY projectscostbreakdown_areaname, projectscostbreakdown_order ASC'); 
     if(is_resource($allRecords)) 
     { 
      while($row = mysql_fetch_assoc($allRecords)) 
      { 
       ?> 
       <tr id="<?php echo $row['projectscostbreakdown_id']; ?>" > 
        <td ><img src="../test/images/icon-drag.png" height="30" style="cursor:pointer;"/></td> 
        <td><b><?php echo $row['projectscostbreakdown_areaname']; ?>:</b> <?php echo $row['projectscostbreakdown_itemname']; ?><br /><?php echo nl2br($row['projectscostbreakdown_itemdescription']); ?></td> 
       </tr> 
       <?php 
      } 
     } 
     ?> 

Answer 1

Tun Sie dies .. ändert

$con = mysqli_connect(DB_SERVER,DB_USER,DB_PASSWORD,DB_NAME); 
$sql ="SELECT * FROM projectscostbreakdown WHERE projectscostbreakdown_projectid='.$projectrfpid.' AND projectscostbreakdown_deleted=1 ORDER BY projectscostbreakdown_areaname, projectscostbreakdown_order ASC"; 

$allRecords = mysqli_query($con, $sql); 

while ($row = mysqli_fetch_array($allRecords , MYSQLI_ASSOC)) { 
    { 
    ?> 
     <tr id="<?php echo $row['projectscostbreakdown_id']; ?>" > 
     <td ><img src="../test/images/icon-drag.png" height="30" style="cursor:pointer;"/></td> 
     <td><b><?php echo $row['projectscostbreakdown_areaname']; ?>:</b> <?php echo $row['projectscostbreakdown_itemname']; ?><br /><?php echo nl2br($row['projectscostbreakdown_itemdescription']); ?></td> 
     </tr> 
    <?php 
    } 
} 

Answer 2

I am writing a general format. 
Fill up the below fields: 
$dbhost  = ""; 
$dbname  = ""; 
$dbuser  = ""; 
$dbpass  = ""; 

//make the connection 

$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass); 

$sql="SELECT * FROM projectscostbreakdown WHERE projectscostbreakdown_projectid=:id AND projectscostbreakdown_deleted=1 ORDER BY projectscostbreakdown_areaname, projectscostbreakdown_order ASC"; 

//always use parameterized queries 

$query=$conn->prepare("$sql"); 

//Bind parameter values using PDO's bindValue method 
$query->bindValue(':id', $projectrfpid); 

$query->execute(); 
$results = $query->fetchAll(PDO::FETCH_ASSOC); 

Look up the PDO section in the php manual to learn more.
