Funções Php Para Conectar No Oracle Ex: Ociparse

[Guest Rubens Saad]

Pessoal, é o seguinte fiz um aplicativo com oracle mas quando executa ocorre o seguinte erro:

Fatal error: Call to undefined function ocilogon() in C:\apachefriends\xampp\htdocs\index.php on line 5

Lembrando que retirei o comentario do extension=php_oracle.dll no PHP.ini

mas mesmo assim continua não funcionando.

Então executei em uma maquina que usava servidor de internet, e ela funcionava o ocilogon, mas quando coloquei a danada pra executar minha aplicação ocorre o seguinte:

Warning: ociparse(): supplied argument is not a valid OCI8-Statement resource

o mesmo com ociexecute():

ocifetch():

ocirollback():

preciso de ajuda, obrigado pessoal

Cara posta ai seu script pra eu dar uma olhada nessas funções não definidas

Antes de ter postado o tópico reclamando, o sr. leu isso: http://phpbrasil.com/articles/article.php/id/575 ?

Cara a aplicação é grande e to rodando em windows e eu tenho as dlls na maquina:

Lembrando que o maior problema é a OCIparse e as outras sequentes.
