8.81.85 mysqli_stmt_bind_param()stmt->bind_param()Lie des variables à une requête MySQL

[ Exemples avec mysqli_stmt_bind_param ]   PHP 5

Style procédural

bool  mysqli_stmt_bind_param ( mysqli_stmt   stmt , string   types , mixed   var1 , mixed   ... )

Style orienté objet (méthode)

mysqli_stmt bool  bind_param ( string   types , mixed   var1 , mixed   ... )

mysqli_stmt_bind_param sert à lier des variables à une requête MySQL préparée par mysqli_prepare . La chaîne types contient un ou plusieurs caractères qui spécifient le type de la variable à lier :
Caractère Description
i Type entier
d Type double (nombre à virgule flottante)
s Type chaîne
b Type BLOB, qui sera envoyé par paquets

Note

Si la taille des données dépasse la taille maximal d'un paquet, ( max_allowed_packet ), vous devez spécifier le caractère b dans le paramètre types et utiliser la fonction mysqli_stmt_send_long_data pour envoyer le message par paquets.

Le nombre de variables et la taille de la chaîne types doivent correspondre au nombre de variables de la requête.

Cette fonction retourne TRUE en cas de succès, FALSE en cas d'échec.

Style orienté objet

<?php
$mysqli
= new mysqli('localhost', 'utilisateur', 'mot_de_passe', 'base');

/* Vérification de la connexion */
if (mysqli_connect_errno()) {
  
printf("Connexion échouée : %s\n", mysqli_connect_error());
  exit();
}

$stmt = $mysqli->prepare("INSERT INTO Langage VALUES (?, ?, ?, ?)");
$stmt->bind_param('sssd', $code, $language, $official, $percent);

$code = 'DEU';
$language = 'Bavarian';
$official = "F";
$percent = 11.2;

/* Exécution de la requête préparée */
$stmt->execute();

printf("%d Ligne insérée.\n", $stmt->affected_rows);

/* Fermeture de la commande */
$stmt->close();

/* Nettoyage de la table Langage */
$mysqli->query("DELETE FROM Langage WHERE Langue='Bavarian'");
printf("%d Ligne effacée.\n", $mysqli->affected_rows);

/* Fermeture de la connexion */
$mysqli->close();
?>
Style procédural

<?php
$link
= mysqli_connect('localhost', 'utilisateur', 'mot_de_passe', 'base');

/* Vérification de la connexion */
if (!$link) {
  
printf("Connexion échouée : %s\n", mysqli_connect_error());
  exit();
}

$stmt = mysqli_prepare($link, "INSERT INTO Langage VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($stmt, 'sssd', $code, $language, $official, $percent);

$code = 'DEU';
$language = 'Bavarian';
$official = "F";
$percent = 11.2;

/* Exécution de la requête préparée */
mysqi_stmt_execute($stmt);

printf("%d ligne insérée.\n", mysqli_stmt_affected_rows($stmt));

/* Fermeture de la commande */
mysqli_stmt_close($stmt);

/* Nettoyage de la table Langage */
mysqli_query($link, "DELETE FROM Langage WHERE Langue='Bavarian'");
printf("%d ligne effacée.\n", mysqli_affected_rows($link));

/* Fermeture de la connexion */
mysqli_close($link);
?>

L'exemple ci-dessus va afficher :


1 ligne insérée.
1 ligne effacée.

mysqli_stmt_bind_result , mysqli_stmt_execute , mysqli_stmt_fetch , mysqli_prepare , mysqli_stmt_send_long_data , mysqli_stmt_errno et mysqli_stmt_error .
