How can we connect a PHP script to MS Access (.mdb) file?
I tried by including following PHP code:
$db_path = $_SERVER['DOCUMENT_ROOT'] . '\WebUpdate\\' . $file_name . '.mdb';
$cfg_dsn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" . $db_path;
$odbcconnect = odbc_connect($cfg_dsn, '', '');
But it failed and I received following error message:
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in C:\web\WebUpdate\index.php on line 41
Here's a sample for a connect and a simple select...
<?php
$db_conn = new COM("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("./Northwind.mdb").";";
$db_conn->open($connstr);
$rS = $db_conn->execute("SELECT * FROM Employees");
$f1 = $rS->Fields(0);
$f2 = $rS->Fields(1);
while (!$rS->EOF)
{
print $f1->value." ".$f2->value."<br />\n";
$rS->MoveNext();
}
$rS->Close();
$db_conn->Close();
?>
In the filename, I'm looking at '\WebUpdate\' - it looks like you have one backslash at the beginning at two at the end. Are you maybe missing a backslash at the beginning?
$db_path = $_SERVER['DOCUMENT_ROOT'] . '\WebUpdate\\' . $file_name . '.mdb';
replace the backslashes with slashes use . '/WebUpdate/' .
it looks like a problem with the path seperators. ISTR that you have to pass backslashes not forward slashes
The following works for me - with an MDB file in the webroot called db4
$defdir = str_replace("/", "\\", $_SERVER["DOCUMENT_ROOT"]);
$dbq = $defdir . "\\db4.mdb";
if (!file_exists($dbq)) { die("Database file $dbq does not exist"); }
$dsn = "DRIVER=Microsoft Access Driver (*.mdb);UID=admin;UserCommitSync=Yes;Threads=3;SafeTransactions=0;PageTimeout=5;MaxScanRows=8;MaxBufferSize=2048;FIL=MS Access;DriverId=25;DefaultDir=$defdir;DBQ=$dbq";
$odbc_conn = odbc_connect($dsn,"","")
or die("Could not connect to Access database $dsn");
I'm not certain if this is a violation of best practices or security, but I would like to throw out this suggestion:
set up an ODBC connection and include the database's password in the odbc advance settings.
give the odbc conn a DSN name then save.
in your code, just set up the connection like:
try {
$conn = #odbc_connect("DSNName", "", "", "SQL_CUR_USE_ODBC");
// un and pw parameters are passed as empty strings since the DSN
// has knowledge of the password already.
// 4th parameter is optional
$exec = #odbc_exec($conn, $insert) or die ("exec error");
echo "success!";
}
catch (Exception $e) {
echo $e->getMessage();
} // end try catch

I am getting following error while using pdo in php.
My database is in C:xmapp/htdocs and php file is in C:xmapp/htdocs/selftest/
My error :
Error:SQLSTATE[HY000] SQLDriverConnect: -1811 [Microsoft][ODBC Microsoft Access Driver] Could not find file '(unknown)'.
My code:
$database_path = $_SERVER['DOCUMENT_ROOT']."\Database11.mdb";
//echo $database_path; die;
try
{
$conn = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$database_path; Uid=$db_username; Pwd=$db_password;");
$conn->setAttribute("PDO::ATTR_ERRMODE,PDO::ERRMODE_Exception");
$stmt=$conn->prepare("insert into user_details(firstname,lastname,filename,sex,qualification) values('$firstname','$lastname','$filename','$sex','$qualification')");
$stmt->exceute();
}
catch(PDOException $e)
{
echo "Error:".$e->getMessage();
}
$conn=null;
Backslash in string needs to be escaped. try
$database_path = $_SERVER['DOCUMENT_ROOT']."\\Database11.mdb";
or simply use forward slash
$database_path = $_SERVER['DOCUMENT_ROOT']."/Database11.mdb";
as forward slash does not have to be escaped but still works perfectly.
Also check if $_SERVER['DOCUMENT_ROOT'] points to the right location.
what is the best way for create a connection between PHP and SQL server that are seperate?(two server: server a SQL and server b PHP)
notice that I use wamp.
I read some articles like below but I want to know is there any new idea?
I test this code that works perfectly:
try{
$user = 'user';
$password = 'pass';
$server="localhost";//or server IP
$database="database";
$conn = odbc_connect("Driver={SQL Server};Server=$server;Database=$database;", $user, $password);
} catch (PDOException $e) {
echo "Failed : " . $e->getMessage() . "\n";
exit;
}
I use PDO_ODBC Method:
1- Install ODBC on server that has wamp and enable PHP_PDO_ODBC extension on your wamp
2- Use this code that supports UTF-8:
try{
$hostname = "IP";
$dbname = "database";
$username = "username";
$pw = "password";
$pdo = new PDO ("odbc:Driver={SQL Server Native Client 10.0};Server=$hostname;Database=$dbname; Uid=$username;Pwd=$pw;");
} catch (PDOException $e) {
echo "Failed : " . $e->getMessage() . "\n";
exit;
}
$query = $pdo->prepare("select field_name from table");
$query->execute();
for($i=0; $row = $query->fetch(); $i++){
echo iconv("CP1256","UTF-8", $row['field_name'])."<br>";
}
3- replace these Items with yours:
IP-database-username-password-field_name-table
4- sometimes you need use "SQL SERVER" instead of "SQL Server Native Client 10.0" and sometimes you need use "IP,port" instead of "IP" and sometimes you need use "ISO-8859-6" instead of "CP1256".
From the PHP manual: http://php.net/manual/en/pdo.construct.php
Example #1 Create a PDO instance via driver invocation
<?php
/* Connect to a SQL Server database using driver invocation */
$dsn = "sqlsrv:Server=12345abcde.database.windows.net;Database=testdb", "UserName#12345abcde", "Password";
try {
$dbh = new PDO($dsn);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
?>
Just change the HOST ip to the IP and port of your mysql server.
I made a php script which'll echo an image if the correct password is entered; so that, nobody can access the images stored on my server directly, thus, making my server more secure. Now, for the php script I used GET method to generate a mysql_query to my database in order to check if the email and password entered by the user are associated with a relevant account and then echo the image from a folder on my server. Now, in order to pass the parameters while runtime, I'm adding them in the URL like this:
http://<mywebserver>/get_image.php/?email=<email>&password=<password>&file_name=<image-file-name>
But, something's wrong with this whole setup, and I'm getting the following error:
Warning: mysql_query() [function.mysql-query]: Access denied for user
'uXXXXXXXXX'#'XX.XX.XX.XX' (using password: NO) in
/home/uXXXXXXXXX/public_html/get_image.php on line 11
Warning: mysql_query() [function.mysql-query]: A link to the server
could not be established in /home/uXXXXXXXXX/public_html/get_image.php
on line 11 Error getting data: Access denied for user
'uXXXXXXXXX'#'XX.XX.XX.XX' (using password: NO)
Here is my php script, get_image.php:
<?php
$file_path = "/ProfilePics/";
if(isset($_GET['email']) && isset($_GET['password']) && isset($_GET['file_name'])) {
$id = "\"" . $_GET['email'] . "\"";
$typed_password = "\"" . $_GET['password'] . "\"";
$file = $_GET['file_name'];
$result = mysql_query("SELECT * FROM students WHERE email = $id AND password = $typed_password") or die ("Error getting data: " . mysql_error()); //line 11
if(!empty($result)) {
if (mysql_num_rows($result) > 0) {
$result = mysql_fetch_array($result);
$user = array();
$user["email"] = $result["email"];
$user["password"] = $result["password"];
$pass = "\"" . $user["password"] . "\"";
if($pass == $typed_password) {
$img_path = $file_path . $file;
echo '<img src="' . $img_path . '" name = "cover" />';
} else {
echo "Incorrect password";
}
} else {
echo "Unable to find user";
}
} else {
echo "Unable to find user";
}
} else {
echo "Required field(s) is missing";
}
?>
I agree, that there are lots of other questions already on stackoverflow stating similar problems. But, I didn't find the solution(s) to those questions applicable for my code. So, any help on this will be highly appreciated. Thank you for your time!
This is because you have not connected your file get_image.php to your MySQL database. Do so as follows:
$host="localhost"; // Host name
$username="username"; // Mysql username
$password="password"; // Mysql password
$db_name="database"; // Database name
$tbl_name="students"; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
Simply replace the information above with the correct information.
You don't seem to be connecting to the database before you try to send queries to it.
It should like something like this:
$conn = new mysqli($servername, $username, $password, $dbname);
Taken from the example here:
http://www.w3schools.com/php/php_mysql_select.asp
Furthermore, if you care, you should consider using PDO or some other method of preventing SQL injection attacks.
SQL Injection:
https://en.wikipedia.org/wiki/SQL_injection
Information on PDO:
http://code.tutsplus.com/tutorials/why-you-should-be-using-phps-pdo-for-database-access--net-12059
setup a database connection first:
$con = mysql_connect('server','username','password');
$rst = mysql_query('select...', $con);
remember that kind of library to access mysql is outdated.
imagine someone logging in with this password:
password = '"; DROP TABLE students;'
or something crafted better.
There are different libraries like PDO or MYSQLI that take cares of this for you.
in newer releases of php standard mysql libis deprecated and removed
Hi guys i want to connect USERNAME,PASSWORD protected MS ACCESS 2000 (.*mdb) database using PHP, ODBC or any other database connection. But given below code show WARNING and doesn't connect to the database. please anyone help.
CODE 1
$mdbFilename = "C:\Documents and Settings\Hp\Desktop\Door\DB\IMSDB.mdb";
$user = 'test';
$password ='123';
$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};DBQ=$mdbFilename;",$user,$password);
if($connection)
{
echo "Success";
}
else
{
exit("Connection Failed: ".$connection);
}
WARNING MESSAGE
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Microsoft Access Driver] You do not have the necessary permissions to use the '(unknown)' object. Have your system administrator or the person who created this object establish the appropriate permissions for you., SQL state 42000 in SQLConnect in C:\xampp\htdocs\punch\test.php on line 6
Output -> Connection Failed
CODE 2
I tried given below code also. there are no any ERRORS or WARNING MESSAGE but not connect to the access database.
$mdbFilename = "C:\Documents and Settings\Hp\Desktop\Door\DB\IMSDB.mdb";
$systemDbFilename = "C:\Documents and Settings\Hp\Desktop\Door\DB\SYSTEM.MDW";
$user = 'test';
$password ='123';
$adoCon = new COM("ADODB.Connection") or die("Cannot start ADO");
$connection= $adoCon->Open("Driver={Microsoft Access Driver (*.mdb)};DBQ=$mdbFilename; SystemDB=$systemDbFilename;Uid=$user; Pwd=$password;");
if(($connection->State) > 0)
{
echo "Success";
}
else
{
exit("Connection Failed: ".$connection);
}
Output -> Connection Failed
CORRECT ANSWER
Finally I found the answer. I tried PDO to connect ODBC.
WORKING CODE
try {
$dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=D:\Door\DB\IMSDB.mdb;SystemDB=D:\Door\DB\SYSTEM.MDW;Uid=test;Pwd=123;");
if($dbh)
{
echo "Connection Success";
}
}
catch (PDOException $e)
{
echo $e->getMessage();
}
I have a simple project and that is to create a function that will check for mysql and odbc connection. I'm already done in creating the function for mysql, here's my sample code:
function check() {
$serverName = 'localhost';
$userName = 'root';
$password = '123';
$db = 'sample';
$conn = mysql_connect($serverName, $userName, $password);
mysql_select_db($db, $conn);
$trans = 'SELECT * FROM Labels';
$trans_result = mysql_query($trans, $conn);
if(!$trans_result) {
die(mysql_error());
} else {
echo "connected";
}
}
Well this one works for me when checking for the mysql connection. Now, my question is, is it possible to create something like this for checking my odbc data source connection? So that would be like
$conn = odbc_connect("spmuse1","" ,""); # Open connection.
$trans = "SELECT French FROM Labels";
$trans_result = odbc_exec($conn, $trans);
if(!$trans_result) {
echo "error?";
} else {
echo "connected";
}
You know what I mean? When I use this code, I always have 2 this error
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified, SQL state IM002 in SQLConnect
Warning: odbc_exec(): supplied argument is not a valid ODBC-Link resource
Please help! Thanks.
First you need to decide vendor of odbc driver, I hope below example will works for you
<?php
// Configure connection parameters
$db_host = "server.mynetwork";
$db_server_name = "Dev_Server";
$db_name = "Dev_Data";
$db_file = 'c:\dbstorage\dev.db';
$db_conn_name = "php_script";
$db_user = "dbuser";
$db_pass = "dbpass";
$connect_string = "Driver={Adaptive Server Anywhere 8.0};".
"CommLinks=tcpip(Host=$db_host);".
"ServerName=$db_server_name;".
"DatabaseName=$db_name;".
"DatabaseFile=$db_file;".
"ConnectionName=$db_conn_name;".
"uid=$db_user;pwd=$db_pass";
// Connect to DB
$conn = odbc_connect($connect_string,'','');
// Query
$qry = "SELECT * FROM my_table";
// Get Result
$trans_result= odbc_exec($conn,$qry);
if(!$trans_result) {
echo "error?";
} else {
echo "connected";
}
?>
I spent several days looking for a simple answer, and came up with this, which works for me:
if (#odbc_connect("DBName","un","pw",SQL_CUR_USE_ODBC) == FALSE){
echo "Database does not exist";
} else {
$connection=odbc_connect("DBName","un","pw",SQL_CUR_USE_ODBC);
echo "Database exists";
}
The # suppresses the basic error if the database does not exist, so the connection try will just return false. Of course if the connection is good, then it creates the connection object.
