Answer 1

Level, Type these are MySQL reserved keywords. You need to enclosed them properly

    <?php
try{
      $bdd=new PDO('mysql:host=localhost;dbname=cmadatabase','root','@Rugby3390', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
        $reponse= $bdd->query('SELECT `IR`,`Level`,`Type`,`ToBeAnalyzed`,`Supplier`,`Consequences`,`Remarks`,SUM(`Level`,`Type`,`Supplier`) AS sommeLvlTypeSup FROM andgate GROUP BY `IR`,`Level`,`Type`,`ToBeAnalyzed`,`Supplier`,`Consequences`,`Remarks` ORDER BY SUM(`Level`,`Type`,`Supplier`) ASC');
    while ($donnees = $reponse->fetch())
    {
        echo '<p>'.$donnees['IR'].','.$donnees['Level'].','.$donnees['Type'].','.$donnees['ToBeAnalyzed'].','.$donnees['Supplier'].','.$donnees['Consequences'].','.$donnees['Remarks'].','.$donnees['sommeLvlTypeSup'].'<p>';
    }
} catch(PDOExpection $px) {
    echo $px->getMessage();
}
    ?>

1st : Alias name in order by clause ORDER BY sommeLvlTypeSup ASC

2nd : Type is mysql keyword . so try to enclose the backticks around table name column name

try
{
    $bdd=new PDO('mysql:host=localhost;dbname=cmadatabase','root','@Rugby3390');
    $bdd->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $reponse= $bdd->query('SELECT `IR`,`Level`,`Type`,`ToBeAnalyzed`,
                                    `Supplier`,`Consequences`,`Remarks`,
                                    SUM(`Level`,`Type`,`Supplier`) AS sommeLvlTypeSup 
                            FROM `andgate` 
                            GROUP BY `IR`,`Level`,`Type`,`ToBeAnalyzed`,
                                     `Supplier`,`Consequences`,`Remarks` 
                            ORDER BY sommeLvlTypeSup  ASC');
    while ($donnees = $reponse->fetch()){
        echo '<p>'.$donnees['IR'].','.$donnees['Level'].','.$donnees['Type'].','.$donnees['ToBeAnalyzed'].','.$donnees['Supplier'].','.$donnees['Consequences'].','.$donnees['Remarks'].','.$donnees['sommeLvlTypeSup'].'<p>';
      }
}

catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage();}
