This paper briefly analyzes the method of PHP connecting to Oracle database. Share to everyone for your reference, specific as follows: PHP provides two sets of functions that are connected to Oracle, namely the Ora_ and OCI functions. Where the Ora_ function is slightly stale. The OCI function update is said to be better. The use of the syntax is almost the same. Your PHP installation options should be able to support both use. Because the OCI func
