[ Exemples avec mysqli_stmt_num_rows ]   PHP 5

Style procédural

int  mysqli_stmt_num_rows ( mysqli_stmt   stmt )

Style orienté objet (méthode)

mysqli_stmt int num_rows

mysqli_stmt_num_rows retourne le nombre de lignes dans le résultat stmt . L'utilisation de la fonction mysqli_stmt_num_rows dépend de l'utilisation ou non de la fonction mysqli_stmt_store_result pour stocker le résultat dans la ressource de commande.

Si vous utilisez mysqli_stmt_store_result , mysqli_stmt_num_rows peut être appelée immédiatement.

Un entier représentant le nombre de lignes dans le résultat.

Style orienté objet

<?php
/* Ouvre la connexion */
$mysqli = new mysqli("localhost", "utilisateur", "mot_de_passe", "base");

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

$query = "SELECT Nom, Pays FROM Ville ORDER BY Name LIMIT 20";
if (
$stmt = $mysqli->prepare($query)) {

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

    
/* Stockage du résultat */
    
$stmt->store_result();

    
printf("Nombre de lignes : %d.\n", $stmt->num_rows);

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

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

<?php
/* Ouvre la connexion */
$link = mysqli_connect("localhost", "utilisateur", "mot_de_passe", "base");

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

$query = "SELECT Nom, Pays FROM Ville ORDER BY Name LIMIT 20";
if (
$stmt = mysqli_prepare($link, $query)) {

    
/* Execution de la requête */
    
mysqli_stmt_execute($stmt);

    
/* Stockage du résultat */
    
mysqli_stmt_store_result($stmt);

    
printf("Nombre de lignes : %d.\n", $stmt->num_rows);

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

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

L'exemple ci-dessus va afficher :


Nombre de lignes : 20.
