Amélioration de code pour gestion plusieurs BDD

Bonjour à tous,

Je gère actuellement plusieurs bases de données identiques, et j'interviens souvent en rajout/modifications de champs sur celles ci.

Sauf que J'ai plusieurs fonctions et a chaque fois que j'appelle une fonction je dois rappeler toutes les informations de connexions, qui sont propres à chaque table.

Code:

---

1 2 3 4 5 6 7 8 9 10 11

if ($nom=='CL_0'){ $host="BDD_0.mysql.db"; $dbname="BDD_0"; $loginbdd="BDD_0"; $passbdd="MDP_0"; $suff_table="extratest_";} if ($nom=='CL_1'){ $host="BDD_1.mysql.db"; $dbname="BDD_1"; $loginbdd="BDD_1"; $passbdd="MDP_1"; $suff_table="extratest_";} if ($nom=='CL_2'){ $host="BDD_2.mysql.db"; $dbname="BDD_2"; $loginbdd="BDD_2"; $passbdd="MDP_2"; $suff_table="extra_";} if ($nom=='CL_3'){ $host="BDD_3.mysql.db"; $dbname="BDD_3"; $loginbdd="BDD_3"; $passbdd="MDP_3"; $suff_table="ext_";} if ($nom=='CL_4'){ $host="BDD_4.mysql.db"; $dbname="BDD_4"; $loginbdd="BDD_4"; $passbdd="MDP_4"; $suff_table="extra_";} if ($nom=='CL_5'){ $host="BDD_5.mysql.db"; $dbname="BDD_5"; $loginbdd="BDD_5"; $passbdd="MDP_5"; $suff_table="extratest_";} if ($nom=='CL_6'){ $host="BDD_6.mysql.db"; $dbname="BDD_6"; $loginbdd="BDD_6"; $passbdd="MDP_6"; $suff_table="extratest_";} if ($nom=='CL_7'){ $host="BDD_7.mysql.db"; $dbname="BDD_7"; $loginbdd="BDD_7"; $passbdd="MDP_7"; $suff_table="ext_";} if ($nom=='CL_8'){ $host="BDD_8.mysql.db"; $dbname="BDD_8"; $loginbdd="BDD_8"; $passbdd="MDP_8"; $suff_table="extra_";} //ect..... 200 CL

Ne puis je pas mettre une seule fonction qui gère les identifications aux données dans les autres fonctions ?

Je n'arrive pas a trouver sur le net des infos concernant des functions en cascade.

Merci de votre aide,

voici mon code :

Bonjour,

il faut factoriser tout ça, le mettre dans un array, et dans une fonction qu'on appelle sur un seul paramètre.

1- A supposer que CHAQUE client a son PROPRE table, alors "CL_xx" doit pouvoir définir un unique paramétrage :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

function get_bdd_parameters_by_nom( $nom ) { // -------------- $bdd_params = array( 'CL_0' => array( 'host'=>'BDD_0.mysql.db', 'dbname'=>'BDD_0', 'loginbdd'=>'BDD_0', 'passbdd'=>'MDP_0', 'suff_table'=>'extratest_' ), 'CL_1' => array( 'host'=>'BDD_1.mysql.db', 'dbname'=>'BDD_1', 'loginbdd'=>'BDD_1', 'passbdd'=>'MDP_1', 'suff_table'=>'extratest_' ), 'CL_2' => array( 'host'=>'BDD_2.mysql.db', 'dbname'=>'BDD_2', 'loginbdd'=>'BDD_2', 'passbdd'=>'MDP_2', 'suff_table'=>'extra_' ), // ... // ... ); // -------------- $bdd_datas = array(); if( array_key_exists( $nom, $bdd_params ) { $bdd_datas = $bdd_params[$nom]; } // -------------- return $bdd_datas; }

---

Utilisation (là où c'est nécessaire) :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

function affchamps($nom, $table, $requete) { // -------------- $bdd_datas = get_bdd_parameters_by_$nom( $nom ); if( !empty($bdd_datas) ) { $host = $bdd_datas['host']; $dbname = $bdd_datas['dbname']; $loginbdd = $bdd_datas['loginbdd']; $passbdd = $bdd_datas['passbdd']; $suff_table = $bdd_datas['suff_table']; } // -------------- // ... }

---

2- Une autre solution (meilleure ?) est de créer une table SQL en BDD (au lieu d'un array) !

3- Si on suppose que ces paramètres ne vont pas changer en cours de script (on traite UN SEUL client à la fois), on peut définir des CONSTANTES :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

function define_bdd_parameters_by_$nom( $nom ) { // -------------- $bdd_params = array( 'CL_0' => array( 'host'=>'BDD_0.mysql.db', 'dbname'=>'BDD_0', 'loginbdd'=>'BDD_0', 'passbdd'=>'MDP_0', 'suff_table'=>'extratest_' ), 'CL_1' => array( 'host'=>'BDD_1.mysql.db', 'dbname'=>'BDD_1', 'loginbdd'=>'BDD_1', 'passbdd'=>'MDP_1', 'suff_table'=>'extratest_' ), 'CL_2' => array( 'host'=>'BDD_2.mysql.db', 'dbname'=>'BDD_2', 'loginbdd'=>'BDD_2', 'passbdd'=>'MDP_2', 'suff_table'=>'extra_' ), // ... // ... ); // -------------- if( array_key_exists( $nom, $bdd_params ) { define( 'BDD_HOST', $bdd_params[$nom]['host']; ); define( 'BDD_NAME', $bdd_params[$nom]['dbname']; ); define( 'BDD_LOGIN', $bdd_params[$nom]['loginbdd']; ); define( 'BDD_PASS', $bdd_params[$nom]['passbdd']; ); define( 'BDD_SUFF', $bdd_params[$nom]['suff_table']; ); } // -------------- }

---

Utilisation : on appelle cette fonction UNE SEULE FOIS, en début de script (quand $nom est défini) :

Code:

---

define_bdd_parameters_by_$nom( $nom );

---

Les CONSTANTES sont alors disponibles dans les autre

Bonsoir jreaux62,


Merci pour ces deux idées, bien que je préfère la première qui correspond mieux à ce que je veux faire précisément.

J'ai fais 2 petites corrections à ton code qui est parfait.

Code:

---

1 2 3 4 5 6 7

$bdd_datas = array(); if( array_key_exists( $nom, $bdd_params )) { $bdd_datas = $bdd_params[$nom]; } // --------------

---

et

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

function affchamps($nom, $table, $requete) { // -------------- $bdd_datas = get_bdd_parameters_by_$nom( $nom ); if( !empty($bdd_datas) ) { $host = $bdd_datas['host']; $dbname = $bdd_datas['dbname']; $loginbdd = $bdd_datas['loginbdd']; $passbdd = $bdd_datas['passbdd']; $suff_table = $bdd_datas['suff_table']; } // -------------- // ... }

---

Merci de ton aide et excellente soirée à tout le monde.
