PHP uses Oracle database

oracle| Data | database "Summary" HP provides 2 major class APIs (application interfaces) to operate Oracle databases. One is the standard Oracle processing function (ORA) and the other is the Oracle 8 call interface function (OCI8). The latter can only be used on Oracle 7 or 8 versions. Because OCI8 offers a number of optimization options, the OCI8 interface should be used whenever possible.

In php3.0 above, PHP has nearly all of the current database processing functions, including Oracle; In this article we have an example of how to use these functions to manipulate Oracle databases.

PHP provides 2 classes of APIs (application interfaces) to operate Oracle databases. One is the standard Oracle processing function (ORA) and the other is the Oracle 8 call interface function (OCI8). The latter can only be used on Oracle 7 or 8 versions. Because OCI8 offers a number of optimization options, the OCI8 interface should be used whenever possible. Here we demonstrate each of these two function sets.

First of all this article assumes that you have installed the Oracle database environment and the PHP development environment. If you do not know how much relationship, there are a lot of relevant good articles on the internet can be referenced.

First step: Create an experimental database

This problem you can ask your database administrator or refer to the Oracle User manual processing, here no more talk

Set up data tables with ORA

Even if you have already created the datasheet, please look at the text of this paragraph. It can tell you how to operate Oracle with PHP+SQL technology.

In this case, we created a data table for storing personal emails.

Related PHP Code:

PutEnv ("Oracle_sid=orasid");
$connection = Ora_logon ("username", "password");
if ($connection = = False) {
  echo ora_errorcode ($connection). ":". Ora_error ($connection). "";
  exit;
}  
$cursor = Ora_open ($connection);
if ($cursor = = False) {
  echo ora_errorcode ($connection). ":". Ora_error ($connection). "";
  exit;
}  
$query = "CREATE Table Email_info".
       "(FullName varchar (255), email_address varchar (255))";
$result = Ora_parse ($cursor, $query);
if ($result = = False) {
  echo ora_errorcode ($cursor). ":". Ora_error ($cursor). "";
  exit;
}
$result = Ora_exec ($cursor);
if ($result = = False) {
  echo ora_errorcode ($cursor). ":". Ora_error ($cursor). "";
  exit;
}
Ora_commit ($connection);
Ora_close ($cursor);
Ora_logoff ($connection);
?> 

To handle Oracle databases, we first have to establish a connection with Oracle.
The syntax is ora_logon (user, password), which returns a Connectid.
Reminder: Before this we must also set the environment variable: ORACLE_SID value.

Now we can interact with Oracle through the ID of the join. The name of the data sheet is called Email_info. The table consists of 2 domains, one storage personal name, (such as: both) a storage email address such as (xiaoyue@163.net)

A cursor Ora_open is also required. This cursor is often used to enumerate data.  We query Oracle's result set with Ora_parse or ora_exec.  Ora_parse the correctness of the SQL syntax and ora_exec executes the corresponding SQL statement. If all this works, then we'll run ora_commit to confirm it.

Create a Table Using OCI

Below we will create an email personal information book. This time using the OCI8 API Directive

related PHP code:

!--? php

PutEnv ("Oracle_sid=orasid");

$connection = Ocilogon ("username", "password");
if ($connection = = False) {
   echo ocierror ($connection).
";
   exit;
}   

$query = "CREATE Table Email_info".
              (fullname varchar (255), email_address varchar (255)) ";

$cursor = Ociparse ($connection, $query);
if ($cursor = = False) {
   echo ocierror ($cursor). "
";
   exit;
}

$result = Ociexecute ($cursor);
if ($result = = False) {
   echo ocierror ($cursor). "
";
   exit;
}

Ocicommit ($connection);
Ocilogoff ($connection);

?>

We can see that the 2 code syntax is almost the same, the difference is only the function name is different, and secondly, in OCI8 we do not need to run the instructions to open the cursor specifically in the call ociparse The system automatically returns a cursor ID.

using ORA to enter data into the datasheet ' Email_info '

When the user browses this script, displays a form that consists of a name, an email input field, and when the user adds a good data click Submit, the script will save the name and email to the ' email_info ' datasheet.

Related PHP Code:

-->
if ($submit = = "click") {
The Submit button was clicked!
Get the input for fullname and email then store it in the database.
PUTENV ("Oracle_sid=orasid");

$connection = Ora_logon ("username", "password");
if ($connection = = False) {
echo Ora_errorcode ($connection). ":". Ora_error ($connection). "
";
Exit
}

$cursor = Ora_open ($connection);
if ($cursor = = False) {
echo Ora_errorcode ($connection). ":". Ora_error ($connection). "
";
Exit
}

$query = "INSERT into email_info values (' $fullname ', ' $email ')";
$result = Ora_parse ($cursor, $query);
if ($result = = False) {
echo Ora_errorcode ($cursor). ":". Ora_error ($cursor). "
";
Exit
}

$result = Ora_exec ($cursor);
if ($result = = False) {
echo Ora_errorcode ($cursor). ":". Ora_error ($cursor). "
";
Exit
}

Ora_commit ($connection);
Ora_close ($cursor);
Ora_logoff ($connection);
}
else{

<input name=fullname> </INPUT>

Please enter your email address

}

?>

Yes, this script must be saved as insert.php because the insert.php is specified as the form handler in the calling page
