Je crée une base de données qui va interagir avec une table SQL.Interaction avec la base de données SQL
Ce que j'ai accompli jusqu'à présent:
- Ajouter des lignes à la table.
- Supprimez les lignes de la table.
- Recherche les lignes de la table.
- Paginez les résultats.
Ce que je dois réaliser:
- Un journal dans l'invite lorsqu'un tente invités à accès à la page.
En fait, j'ai installé avec succès un script de connexion pour elle, mais il semble ne pas fonctionner correctement, est ici l'erreur:
Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 77824 bytes) in /home/vol3/byethost12.com/b12_3598660/htdocs/coordbase/database.php on line 238
Maintenant que je n'ai pas la permission de laisser plus mémoire de mon hôte, j'aurais besoin d'un moyen de contourner cela. J'ai déjà essayé de séparer le fichier en plusieurs pages, mais il semble qu'il essayait toujours d'allouer la même quantité d'octets.

J'ai remarqué que la mémoire dépasse la limite quand je session.php inclure à mon dossier. Le problème est que j'ai besoin de ce fichier pour mon invite de connexion au travail.
et que voulez-vous exactement que quelqu'un fasse avec cela? –
Hmmmm, il semble que mon post est trop long, session .php ne rentre pas. – user151797
C'est une page où les gens peuvent ajouter et supprimer des données dans une base de données SQL. Il va également rechercher des données dans celui-ci. C'est comme une base de données géante pour stocker des informations. – user151797
