When php connects to Oracle, it prompts CalltoundefinedfunctionOra_Logon(), how to solve it?

PHP connects to Oracle and prompts Call to undefined function Ora_Logon()
A short piece of code written according to the information

<?

if ($cOnn=Ora_Logon( “hr@ TNSNAME “, “hr “))
{
echo “SUCCESS ! Connected to database\n “;
}
else
{
echo “Failed 🙁 Could not connect to database\n “;}
Ora_Logoff($conn);
phpinfo();
?>

Prompt Ora_Logon function is defined , why?

I have removed the semicolon of extension=php_oci8.dll in php.ini
and imported php_oci8.dll into windows/system32.

It’s not like you You can install the Oracle extension…

And ora_logon belongs to CXIII. Oracle function (obsolete)

You have to use CVII. Oracle function

Did you config your php with Oracle while installing it? Please check below

./configure –prefix=/appbin/php –with-apxs2=/appbin/apache/bin/apxs –with- oci8=$ORACLE_HOME

$ORACLE_HOME is path which your Oracle clinet/server located,

then use oci_connect() or use oci_newconnect(), Please check php doc for detail
