How to Connect to a Oracle/Peoplesoft Database using PHP

Entry from within tnsnames.ora file

ORA_SERVICE = (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME=ora_service)))

 This is sample script to connect and execute a query:

$db_conn["host"] = "ORA_SERVICE"; # service name in the tnsnames.ora file 
$db_conn["user"] = "myuser"; # username 
$db_conn["pass"] = "mypass"; # password 
$db_conn["library"] = "OCI"; 
 
$connect_id = ocilogon($db_conn["user"], $db_conn["pass"], $db_conn["host"]); 
 
$query = "SELECT * FROM table"; 
$statement = ociparse($connect_id, $query); 
ociexecute($statement); 
 
$result = array(); while(ocifetchinto($statement, $tmp, OCI_ASSOC + OCI_RETURN_NULLS + OCI_RETURN_LOBS)) { 
  array_push($result, $tmp); } 
 
ocifreestatement($statement); 
 
var_dump($result); # result is here
