I am using Oracle 1Og express edition and EasyPHP v5.3.5.0
My oracle database in running on port 8080.
I can not connect the oracle database using my php program.
I am confused about the 3rd parameter of the oci_connect statement.
Here is my code.
<?php
$conn = oci_connect("scott", "tiger","localhost/XE");
if (!$conn)
{
$m = oci_error();
echo $m['message'], "\n";
exit;
}
else
{
print "Connected to Oracle!";
}
oci_close($conn);
?>
Can you try this method instead? (granted you know your tnsnames entry)
<?php
$tns = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA=(SID=XE)))" ;
if($conn = OCILogon("scott", "tiger", $tns))
{
echo “Connected.\n”;
OCILogoff($conn);
}
else
{
$err = OCIError();
echo “Connection ERR.” . $err[text] . "\n";
}
?>

In Laravel, I set my SQL Server connection string like this in the .env file: -
DB_CONNECTION=mssql
DB_HOST=sql-server123.database.windows.net
DB_PORT=1433
DB_DATABASE=dev-db-123
DB_USERNAME=user123
DB_PASSWORD=pass123
But now I'd like to format my connection string to connect to SQL Azure using the system-assigned managed identity provided by Azure Cloud.
As a test, I used Microsoft's example to connect using a System Managed Identity: -
https://learn.microsoft.com/en-us/sql/connect/php/azure-active-directory?view=sql-server-ver15
<?php
$azureServer = 'myazureserver.database.windows.net';
$azureDatabase = 'myazuredatabase';
$connectionInfo = array('Database'=>$azureDatabase,
'Authentication'=>'ActiveDirectoryMsi');
$conn = sqlsrv_connect($azureServer, $connectionInfo);
if ($conn === false) {
echo "Could not connect with Authentication=ActiveDirectoryMsi (system-assigned).\n";
print_r(sqlsrv_errors());
} else {
echo "Connected successfully with Authentication=ActiveDirectoryMsi (system-assigned).\n";
$tsql = "SELECT ##Version AS SQL_VERSION";
$stmt = sqlsrv_query($conn, $tsql);
if ($stmt === false) {
echo "Failed to run the simple query (system-assigned).\n";
print_r(sqlsrv_errors());
} else {
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
echo $row['SQL_VERSION'] . PHP_EOL;
}
sqlsrv_free_stmt($stmt);
}
sqlsrv_close($conn);
}
?>
Where in Laravel can I set the connection string to use: -
'Authentication'=>'ActiveDirectoryMsi'
Try this and let me know:
DB_CONNECTION=mssql
DB_HOST=sql-server123.database.windows.net
DB_PORT=1433
DB_DATABASE=dev-db-123
DB_USERNAME=user123
DB_PASSWORD=pass123
AUTHENTICATION=ActiveDirectoryMsi
or in alternative:
DB_AUTHENTICATION=ActiveDirectoryMsi

$server_ip = "my ubuntu ip";
$server_port = "my ubuntu port";

if (ssh2_auth_password($connection, $server_user, $user_pw)) {

}
$mysql_ip = '10.41.12.71';
$mysql_default_port = '3306';
$tunnel = ssh2_tunnel($connection,$mysql_ip,$mysql_default_port);
if($tunnel) {
echo "tunnel created<br>";
}else {
echo "tunnel creation failed";
die();

if ($dbconn) {
echo $dbname." connected<br>";
} else {
echo "DBConnection failed: " . $dbconn->connect_error;
}
// $insert_sql = " insert into test_table values('0001','wlsdhks0423'); ";
// $result = mysqli_query($dbconn,$insert_sql);
// if($result) {
// echo "data insert success<br>";
// }
// else {
// echo "data insert failed : ".mysqli_error($dbconn);
// }
$select_sql = " select * from test_table; ";
$result = mysqli_query($dbconn,$select_sql);
if($result) {
echo "selected rows : ".mysqli_num_rows($result)."<br>";
$row = mysqli_fetch_array($result);
$key = $row['test_key'];
$value = $row['test_value'];
echo "key = ".$key."<br>value = ".$value;

This is my code. mysql is on ubuntu device.
And I think I can access ubuntu, but mysql connection is failed
this php's output is
Authentication Successful!
tunnel created
test connected
and if i use this line
$dbconn = mysqli_connect($tunnel,$mysql_user,$mysql_user_pw,$dbname);
then output is
Authentication Successful!
tunnel created
DBConnection failed:
The obvious thing is that $connection and $tunnel has no problem.
I had tested them. And works well.
This is an exact duplicate of the postgresql question because they both exist for the same reason. You're both trying to connect a service over a SSH Tunnel by using ssh2_tunnel incorrectly.
ssh2_tunnel returns a resource aka a file pointer
The ssh2_tunnel() return a socket object which means you can operate this socket object just like you use standard socket function.
I have such code:
fwrite($ssh_tunnel, $db_password);
while (!feof($ssh_tunnel)) {
echo fgets($ssh_tunnel, 1280);
}
and I get such result:
a 5.5.5-10.3.34-MariaDB-cll-lve��=^Aile5x����}.hBNEM5_^:Gmysql_native_password!��#08S01Got packets out of order
I think fwrite can send something to such tunnel we have created, so I am currently figuring out what data should be sent to.
I'm trying to create a basic PHP/MySQL test script. When I attempt to print the two tables in the database I created ('andrew'), the PHP output returns none. However, when I run the same command ('show tables;') through the MySQL 5.6 Command Line, both tables are returned. Any idea what I'm doing wrong?
<?php
$host='localhost';
$username='root';
$password='*****';
$database='andrew';
$connect=mysqli_connect($host,$username,$password,$database);
if(mysqli_connect_errno())
{echo 'Failed to connect to MySQL: ' . mysqli_connect_error();
}
else{echo 'Connected to MySQL! </ br>';}
$result=mysqli_query($connect,'show tables;');
if(!$result){
echo 'Nope';}
else{echo '<p>Result!!!</p>';}
echo '<p>Tables in database:</p>';
echo "<ul>";
while($row = mysqli_fetch_assoc($result)){
print_r ($row);}
echo "</ul>";
?>
Try run this sql in your mysql command line:
use mysql;
grant all on andrew.* to 'root'#'localhost' identified by 'root password';
Then again try to run your script.
The script you have is working properly.
DETAILS:
$host='localhost';
$username='root';
$password='';
$database='test';
OUTPUT:
Connected to MySQL!
Result!!!
Tables in database:
Array ( [Tables_in_test] => tester )
<?php
$host='localhost';
$username='root';
$password='*****';
$database='andrew';
$connect=mysqli_connect($host,$username,$password,$database);
mysqli_select_db($connect,$database);
if(mysqli_connect_errno()) {
echo 'Failed to connect to MySQL: ' . mysqli_connect_error();
}
else {
echo 'Connected to MySQL! </ br>';
}
$result=mysqli_query($connect,'your sql query');
if(!$result){
echo 'Nope';
} else{
echo '<p>Result!!!</p>';
}
echo '<p>Tables in database:</p>';
echo "<ul>";
while($row = mysqli_fetch_array($result)){
print_r($row);
}
echo "</ul>";
?>
Heres my code. Simple.
<?php
echo 'start<br>';
//Do the conntection
$checkconnection = mysql_connect('localhost', 'root', 'rootpass');
//Check if it's valid
if(!$checkconnection) {
echo 'CheckFailed';
} else{
echo 'CheckSucess';
}
echo 'end'; ?>
but I only can see 'start'. There is no 'CheckFailed', 'CheckSucess', 'end'
What should I do?
I already install mysql, create database, create tables, of course.
<?php
// Create connection
$con=mysqli_connect("localhost","root","root","database");
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
return false;
}
$result = mysqli_query($con, "SELECT * FROM table;");
?>
Hi I am facing a unique issue with my PHP script.Here is my code. After writeToDB() is executed I dont see the echo ("<script> top.location.href=www.facebook.com</script>");
Can someone let me know why my script stops executing after writing to db?
<?php
function writeToDB($access_token,$uid,$username,$birthday,$gender,$age)
{
/* Database Connection */
$user = "xxxx";
$password = "xxxx";
$host = "xxxxxxxxxxxxxxxxxx";
//connect to database, where tsnames.ora is setup
$connect_obj = oci_connect($user, $password, $host);
if ($connect_obj) {
error_log("connected okay");
} else {
$err = OCIError();
echo "Oracle connection error " . $err[text];
return;
}
$select_query = "SELECT USER_ID FROM FBTABLE WHERE USER_ID= '$uid'";
$select_sql_stmt = oci_parse($connect_obj, $select_query);
//execute statement
try {
$r = oci_execute($select_sql_stmt, OCI_DEFAULT);
if (!$r) {
$p = oci_error($select_sql_stmt);
echo "Oci Execute error";
}
} catch (Exception $e) {
echo "<br>Failed to get database info" . $e->getMessage();
}
$user_id_in_db = null;
while (oci_fetch($select_sql_stmt)) {
$user_id_in_db = oci_result($select_sql_stmt, 'USER_ID');
}
// User already exists in db so update instead of insert
if ($user_id_in_db != null) {
$query ="UPDATE FBTABLE SET ACCESS_TOKEN='$access_token' WHERE USER_ID='$uid'";
} else {
$query = "INSERT INTO FBTABLE(ACCESS_TOKEN, USER_ID,USER_NAME,BIRTHDAY,GENDER,AGE)
VALUES
('$access_token','$uid','$username','$birthday','$gender','$age')";
}
//create sql statement
$sql_statement = oci_parse($connect_obj, $query);
//execute statement
try {
$r = oci_execute($sql_statement, OCI_DEFAULT);
if (!$r) {
$p = oci_error($sql_statement);
echo "Oci Execute error";
}
} catch (Exception $e) {
echo "<br>Failed to get database info" . $e->getMessage();
}
//Commit transaction
$committed = oci_commit($connect_obj);
//Test whether commit was successful. If error occurred, return error message
if (!$committed) {
$error = oci_error($conn);
echo 'Commit failed. Oracle reports: ' . $error['message'];
}
//close the connection
$oci_free_statement($sql_statement);
if (oci_close($connect_obj)) {
echo " oci connection not closed!!!";
}
//close the connection
$oci_free_statement($sql_statement);
}
?>
<html>
<body>
<?php
$access_token = $_GET['access_token'];
$uid = $_GET['uid'];
$username = $_GET['username'];
$birthday = $_GET['birthday'];
$gender = $_GET['gender'];
$age = $_GET['age'];
echo $username;
writeToDB($access_token,$uid,$username,$birthday,$gender,$age);
echo ("<script> top.location.href=www.facebook.com</script>");
?>
</body>
</html>
i think error is in $oci_free_statement($sql_statement); must be oci_free_statement($sql_statement); extra $ before oci_free_statement
http://php.net/manual/en/function.oci-free-statement.php
no any error show because of error_display is off
Your JavaScript code should be
echo ("<script> top.location.href='http://www.facebook.com';</script>");
It's happen because writeToDB() causes error. You don't see this error because error_display is off or error_reporting = 0
Also maybe you didn't install OCI8. So when you call oci_connect it will cause error.
Thanks.
you are not using quotes around the string:
www.facebook.com should be 'www.facebook.com'
