Ajouter des chaînes numériques avec des virgules

Question

J'ai une boucle qui ajoute les résultats de ma base de données. Les valeurs sont des chaînes numériques dans ce format: $$$, $$$ $$ Je ne parviens pas à obtenir les résultats d'ajouter et d'afficher dans ce même format.

function totals(){ 
    $result = mysql_query("SELECT meta_value FROM postmeta WHERE postmeta.meta_key = 'Value'"); 
    $value = 0; 
    while($row = mysql_fetch_array($result)) { 
     $value = $value + str_replace(',', '', $row['meta_value']); 
    } 
    echo "Worth $".$value."!"; 
}; 

En utilisant ce qui précède, je reçois quelque chose comme Worth 653987.32 $. Maintenant, j'ai besoin de réinsérer les virgules donc j'essaie ceci:

$value = number_format($value, 2, '.', ','); 

Mais alors je reçois une valeur de 10.000,00 $!

sortie comme demandé:

Il est clair que quelque chose ne va pas. Quelqu'un peut-il aider?

Answer 1

Que produit-il? Il semble que votre numéro soit trop grand pour tenir dans 31bits, mais il est difficile de savoir jusqu'à ce que je vois votre sortie exacte.

Etes-vous sûr que toutes vos valeurs $row['meta_value'] sont des nombres simples avec des virgules? Essayez de le faire:

while($row = mysql_fetch_array($result)) { 
    echo "Value: {$row['meta_value']}\n"; 
    $value += str_replace(',', '', $row['meta_value']); 
} 

echo "final value: $value\n"; 
echo "formatted: ".number_format($value, 2)."\n"; 

Je me demande si certaines valeurs ne sont pas conformes à vos attentes.

Answer 2

Vous pouvez encore jeter la valeur en un nombre flottant:

(float)str_replace(',','',$row['meta_value']) 

EDIT:

code complet:

function totals() { 
    $result = mysql_query("SELECT meta_value FROM postmeta WHERE postmeta.meta_key = 'Value'"); 
    $value = 0; 
    while ($row = mysql_fetch_array($result)) { 
     $value += (float)str_replace(',', '', $row['meta_value']); 
    } 
    echo "Worth \$$value!"; 
}; 

Answer 3

Vous pouvez également les obtenir correctement mis en forme de la requête lui-même et opérer sur le terrain que vous voulez:

SELECT replace(meta_value, ',', '') as number_value, meta_value as original_value 
FROM postmeta 
WHERE postmeta.meta_key = 'Value'
