PHP connection oracle database_PHP tutorial
PHP connection to access Oracle uses the oci function. The following is a compiled document
1. Install Apache and php packages
yum install -y httpd php*
2. Download Oracle components
oracle-instantclient-basic-10.2.0.4-1.i386.rpm
oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm
oracle-instantclient-devel-10.2.0.4-1.i386.rpm
oracle-instantclient-odbc-10.2.0.4-1.i386.rpm
#rpm -ivh oracle-instantclient* (all four components installed)
At this time, the /usr/lib/oracle/10.2.0.4/client/lib/ directory will be generated
3. Modify the /etc/ld.so.conf file
#vim /etc/ld.so.conf
Add the following content
/usr/lib/oracle/10.2.0.4/client/lib/
#ldconfig (execution command)
4. Download OCI8 component
#tar zxvf oci8-1.4.1.tgz
5. Edit OCI8 module
#cd oci8-1.4.1
#phpize (execute command)
#./configure --with-oci8=instantclient,/usr/lib/oracle/10.2.0.4/client/lib/
#make install
After success, the system will prompt you: oci8.so has been successfully placed in the /usr/lib/php/modules/ directory
6. Modify the php.ini file
#vim /etc/php.ini
Add the following content
extension=oci8.so
7. Restart the Apache service
service httpd restart
8. Use the phpinfo() function to view
9. Edit the php code to connect and test the oracle database
$conn = oci_connect('scott', 'oracle', '192.168.12.133/orcl');
if (!$conn) {
$e = oci_error();
print htmlentities($e['message']);
exit;
}
$query = 'select ename,sal from scott.emp';
$stid = oci_parse($conn, $query);
if (!$stid) {
$e = oci_error($conn);
print htmlentities($e['message']);
exit;
}
$r = oci_execute($stid, OCI_DEFAULT);
if(!$r) {
$e = oci_error($stid);
echo htmlentities($e['message']);
exit;
}
print '
'.($item?htmlentities($item):' ').' | ';
oci_close($conn);
?>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
