当我使用foreach循环浏览sql请求的结果时出现问题我得到了这个错误queryWarning：当我使用foreach时非法的字符串偏移量：请有人帮助我，我已经失去了

这是我的代码：

connexion.php：

$bdd = new PDO('mysql:host=localhost;dbname=rep', '******', '******');

sendMail.php

include("connexion.php");
require 'PHPMailerAutoload.php';

$sql= $bdd->query('SELECT count(id) as id from inci where retour="0" AND 
atelier="test"');
       $data = $sql->fetch();

$mail = new PHPMailer;

$mail->SMTPDebug = 3;                               

$mail->isSMTP();                                     
$mail->Host = '******';                   
$mail->SMTPAuth = true;                              
$mail->Username = '******';                 
$mail->Password = '*******';                     
$mail->SMTPSecure = 'tls';                            
$mail->Port = 587;                                    
$mail->setFrom('******');
$mail->addAddress('******', 'name');     

$mail->Subject = ' valider';
$mail->Body    = "
<table>
 <thead>
<tr>

                        <th> Destinataire     |</th>
                        <th> Atelier          |</th>
                        <th> Anomalie                                                
</th>

</tr>
 </thead>
 "; 

 foreach($data as $raw) {
                $destinataire=$raw['destinataire'];
                $atelier=$raw['atelier'];
                $anomalie=$raw['anomalie'];




 $mail->Body .="
 <tr>


                        <td>  ".$destinataire."</td>
                        <td>  ".$atelier." </td>
                        <td>  ".$anomalie." </td>

</tr>
</table>

      @endforeach

";
     }
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';


if(!$mail->send()) {
  echo 'Message could not be sent.';
 echo 'Mailer Error : ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

错误：

您应该在第7行使用fetchAll()代替fetch()：

$data = $sql->fetchAll();
foreach ($data as $raw) {
    $destinataire = $raw['destinataire'];
    $atelier = $raw['atelier'];
    $anomalie = $raw['anomalie'];
}

方法fetch()仅返回结果集中的下一行。因此，另一种选择是在一段时间内使用fetch()：

while ($raw = $sql->fetch()) {
    $destinataire = $raw['destinataire'];
    $atelier = $raw['atelier'];
    $anomalie = $raw['anomalie'];

    // rest of your code
}
