[PHP-DB] Join Sentences

[Gaby]

Hi,

( Excuse me for my english )

I wish execute in PHP some consecutives sentences , but if one of them returns un 
error, the program must'n execute anyone. I need one set of sentences that executes 
the code like one.

I don't know if I explain ... Thanks a lot.

Lo que me gustaria es ejecutar un grupo de sentencias como si fueran solo una
