PDO: Could not find driver php/mysql - php

i'm having issues connecting to my database on a web host that I have, i'm using the following:
$dsn = 'mysql:host=mysql1.hosting.digiweb.ie;dbname=mydbname';
$user = 'myusername';
$password = 'mypassword';
According to the website: Host Name mysql1.hosting.digiweb.ie (ip address)
as the title says i'm getting a could not find driver error, am i entering the host incorrectly i tried entering whats above and also the ip address - Thanks!
Edit:
Here's all my code
<?php
$dsn = 'mysql:host=localhost;dbname=';
$user = '';
$password = '';
try {
// Connect and create the PDO object
$dbh = new PDO($dsn, $user, $password);
$dbh->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
echo 'Database connection failed - ';
echo $e->getMessage();
exit;
}
echo 'works';
?>

go to your php.ini file and uncomment this line
extension=php_pdo_mysql.dll
and then restart your apache

Change your extension dir to be absolute in php.ini. I changed it from
extension_dir = "ext"
to
extension_dir = "C:/{PATH TO PHP DIRECTORY}/ext"
and it worked.

PHP - oci_connect not found

I researched and found out oci_connect() is the way to go. I found out that i could either use the Connect Name from the tnsnames.ora file or use an easy connect syntax. Since my database isn't locally stored and I had no idea where the said, tnsnames.ora file was located in apex.oracle.com, I went with easy connect strings.Here's what I've done so far.
$username = "myemail";
$host = "apex.oracle.com";
$dbname = "name";
$password = "password";
// url = username#host/db_name
$dburl = $username . "#".$host."/".$dbname;
$conn = oci_connect ($username, $password, $dburl);
if(!$conn) echo "Connection failed";
I get a
Call to undefined function oci_connect()
So what would be the way to go?
UPDATE 1:
Here's the list of things I did:
Installed Oracle DB
Unzipped Oracle Instance client
Set the environment variables
Uncommented the extension=php_oci8_12c.dll in php.ini
Copied all the *.dll files from the instance client folder to xampp/php and xampp/apache/bin
also made sure the php/ext folder had the required dlls.
That was last night. I have restarted my PC multiple times, APACHE with it but I'm still getting this error:
Call to undefined function oci_connect()
At this point I'm frustrated and don't know where to go from here. PHP just doesn't seem to link up to oci8. I can view the databases I made from Database Configuration Assistant in cmd from 'sqlplus' command and a few select statements. So everything seems to be setup right, its just the php that's having problems trying to use oci_connect().
My database.php, now is setup as:
public function __construct()
{
error_reporting(E_ALL);
if (function_exists("oci_connect")) {
echo "oci_connect found\n";
} else {
echo "oci_connect not found\n";
exit;
}
$host = 'localhost';
$port = '1521';
// Oracle service name (instance)
$db_name = 'haatbazaar';
$db_username = "SYSTEM";
$db_password = "root";
$tns = "(DESCRIPTION =
(CONNECT_TIMEOUT=3)(RETRY_COUNT=0)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = $host)(PORT = $port))
)
(CONNECT_DATA =
(SERVICE_NAME = $db_name)
)
)";
$tns = "$host:$port/$db_name";
try {
$conn = oci_connect($db_username, $db_password, $tns);
if (!$conn) {
$e = oci_error();
throw new Exception($e['message']);
}
echo "Connection OK\n";
$stid = oci_parse($conn, 'SELECT * FROM ALL_TABLES');
if (!$stid) {
$e = oci_error($conn);
throw new Exception($e['message']);
}
// Perform the logic of the query
$r = oci_execute($stid);
if (!$r) {
$e = oci_error($stid);
throw new Exception($e['message']);
}
// Fetch the results of the query
while ($row = oci_fetch_array($stid, OCI_ASSOC + OCI_RETURN_NULLS)) {
$row = array_change_key_case($row, CASE_LOWER);
print_r($row);
break;
}
// Close statement
oci_free_statement($stid);
// Disconnect
oci_close($conn);
}
catch (Exception $e) {
print_r($e);
}
}
And it outputs:
oci_connect not found
OCI8 is listed in my phpInfo().
Okay I found out the culprit behind this whole ordeal. I had set the PATH Environment Variables but apparently forgot to add a new system environment variable named TNS_ADMIN and set the directory to PATH/TO/INSTANCE/CLIENT.
Here's the list of System Environment variable you need to add:
Edit PATH system variable and add the $ORACLE_HOME/bin dir
Edit PATH system variable and add the Instance Client dir
Add new system variable, name it TNS_ADMIN and add the Instance Client dir
I hope this helps those who come looking.
First, this has been asked before, but Oracle doesn't allow remote database connections to their free apex.oracle.com example service. Sorry. You can only interact with it through the web interface.
Second, if you do find a remote Oracle db to connect to, you'll need to install the Oracle Instant Client for your OS, and configure the PHP OCI8 extension.

I have the error: SQLSTATE[HY000] [2005] Unknown MySQL server host

I'm using a mysql database. I would like to connect to it with the script i wrote :
<?php
function getDatabase() {
$host = 'localhost:3306';
$db = 'freya';
$login = 'root';
$pw = 'helloitsme';
try {
return new PDO('mysql:host='.$host.';dbname='.$db.';charset=utf8', $login, $pw);
} catch (Exception $e) {
die('Erreur : '.$e->getMessage());
}
}
$db = getDatabase();
I have seen that this error is recurent but none of the solutions worked for.
I checked the my.cnf, and i'm sure that i'm using the port where the mysql db is.
I'm also sure that the db name, the login and the password are correct, because i'm using them to reach the db with the shell.
What could be the problem ?
You don't need to specify the port as 3306 is default for mysql, but if you do, the correct connection string is
'mysql:host=localhost;port=3306 ...'

PHP connection "Failed to get DB handle: could not find driver"

I'm using the following code to try and connect:
try {
$hostname = "*****";
$port = 1443;
$dbname = "*******";
$username = "********";
$pw = "************";
$dbh = new PDO ("dblib:host=$hostname:$port;dbname=$dbname","$username","$pw");
} catch (PDOException $e) {
echo "Failed to get DB handle: " . $e->getMessage() . "\n";
exit;
}
This is my Error:
Failed to get DB handle: could not find driver
And the DLL Files are already in the php/ext and modified in the php.ini
What else can I do?
There is following of possibility here,
enable mssql in php.ini
;extension=php_mssql.dll
to
extension=php_mssql.dll
try editing your setting at the php.ini mssql.secure_connection must be set to on.
mssql_connect can use secured connection if php is configured ...
go into the php.ini and verify the mssql.secure_connection parameter
[MSSQL]
mssql.secure_connection = On
3.Try this:
Uncomment the following in php.ini by removing the ";"
;extension=php_pgsql.dll
I hope this will help you.

could not find driver php&pdo [duplicate]

i'm having issues connecting to my database on a web host that I have, i'm using the following:
$dsn = 'mysql:host=mysql1.hosting.digiweb.ie;dbname=mydbname';
$user = 'myusername';
$password = 'mypassword';
According to the website: Host Name mysql1.hosting.digiweb.ie (ip address)
as the title says i'm getting a could not find driver error, am i entering the host incorrectly i tried entering whats above and also the ip address - Thanks!
Edit:
Here's all my code
<?php
$dsn = 'mysql:host=localhost;dbname=';
$user = '';
$password = '';
try {
// Connect and create the PDO object
$dbh = new PDO($dsn, $user, $password);
$dbh->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
echo 'Database connection failed - ';
echo $e->getMessage();
exit;
}
echo 'works';
?>
go to your php.ini file and uncomment this line
extension=php_pdo_mysql.dll
and then restart your apache
Change your extension dir to be absolute in php.ini. I changed it from
extension_dir = "ext"
to
extension_dir = "C:/{PATH TO PHP DIRECTORY}/ext"
and it worked.

PDOException "could not find driver" on MAMP

I'm trying to work with PDO on my localhost. I'm running MAMP on OSX 10.7.4.
I've checked phpinfo(), and as far as I can see I should be fine.
I checked the php.ini to see that "extension=pdo_mysql.so" is in fact uncommented.
I read some were that I had to make the file PROJECTFOLDER/config/parameters.ini with the following content so i did, but with no luck. (Changed it to reflect my setup of cause)
database_driver = pdo_mysql
database_host = localhost
database_port =
database_name = databasename
database_user = msqlusername
database_password = mysqlpassword//if not make blank
mailer_transport = smtp
mailer_host = localhost
mailer_user =
mailer_password =
locale = en
secret = ThisTokenIsNotSoSecretChangeIt
Any ideas as to how I can get PDO up and running?
BTW I'm using the following code to make the connection:
try {
$host = 'localhost';
$dbname = 'ifjernsyn';
$user = 'root';
$pass = 'root';
# MS SQL Server and Sybase with PDO_DBLIB
$DBH = new PDO("mssql:host=$host;dbname=$dbname, $user, $pass");
$DBH = new PDO("sybase:host=$host;dbname=$dbname, $user, $pass");
# MySQL with PDO_MYSQL
$DBH = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
# SQLite Database
$DBH = new PDO("sqlite:my/database/path/database.db");
}
catch(PDOException $e) {
echo $e->getMessage();
}
So there is not mssql and sybase 's driver.
You need PDO_DBLIB to access Microsoft SQL Server and Sybase databases.
