from:"Info"

Thanks for that great response Geoff.

That very well may be what is wrong, however, my problem is I don't have admin 
access to this server - it hosted in a BaaS site where they do all the admin. 
They do provide mysql command line access and it works, but it won't let me log 
in as root, not even on the command line.

Where is the '@'ip70-162-142-180.ph.ph.cox.net' part coming from? I have to 
assume mysql_connect itself is appending that in the call since it's not part 
of the contents of the variable I pass from the form.

And if I can't get server root access then that begs the question: how do I 
tell mysql_connect to turn that off and just send the user as-is?

Thanks,

 Night now this is just a test server. On the real thing I'll do it right.
 
 FWIW, the error you describe is one that I've seen often when setting
 up a new development/test server. In my case, the issue has arisen
 because the user doesn't have permission to connect to the database.
 This drove me nuts for a couple of days until I read the error message
 a little more carefully. In your case, you have:
 
 *Warning*: mysql_connect() [function.mysql-connect
 http://localhost/wservices/function.mysql-connect]: Access denied for
 user 'user'@'ip70-162-142-180.ph.ph.cox.net' (using password: YES) in
 */Library/WebServer/Documents/wservices/connect.php* on line *29*
 
 Notice that the username isn't just 'user', but 'user@host'.
 Hopefully, you have access to the MySQL command line on the MySQL
 server. If so, log on as root then do:
 
 mysqluse mysql;
 mysqlselect user,host from user;
 
 In the results table, check which hosts your user is permitted to
 connect from. Let's say for now that your results table looks like:
 
  +--+---+
  | user | host  |
  +--+---+
  | root | myserver  |
  | root | 127.0.0.1 |
  | debian-sys-maint | localhost |
  | root | localhost |
  +--+---+
 
 To permit a user to connect from any host, change the host value to '%'
 e.g:
 mysqlupdate user set host='%' where user='root' and host='myserver';
 permits user 'root' to connect from any host rather than just from
 'myserver', the loopback IP address, and 'localhost'.
 
 If that doesn't work, you probably need to configure mysql to permit
 connections from any host. To do this, edit my.cnf (which should be
 /etc/mysql/my.cnf in Debian-based systems) and search for the line:
  bind-address  = 127.0.0.1
 Comment this out and replace with:
  bind-address  = 0.0.0.0
 
 Hopefully, that'll sort out the one test user you've tried so far.
 Note that you'll need to take responsibility for verifying your users
 at the application level or you'll need to create a new entry in the
 user table with CREATE USER; GRANT appropriate privileges; and then
 update the user's record to permit connection from the appropriate
 host(s).

[PHP] Re: mysql_connect noob question

Thanks Geoff,

I am aware of the security implications. I will deal with that later. Right now 
I am just trying to get the WS architecture working.

I am logging in with the creds the hosting provider gave me (xeround.com)

When I use those creds on the mysql command line, or hard-code them in the 
script, all works fine. It is only when I pass those values from my HTML form 
to the script that it fails - which was why I posted the question originally - 
the authentication works fine, but when entered from a form and passed to the 
script it fails, which is what is so baffling.

I don't understand why mysql_connect should append something in the case of a 
passed variable but not in the case of a local variable. Unless there is 
something in the form parsing machinery I am unaware of.

And I am trying both from the same host.

Thanks,

 Perhaps you can issue the commands of my previous email while logged
 in as the user who's credentials they've given to you. That said, I
 wouldn't be surprised if they denied you update privs on any of the

 I suspect that it's coming from DNS and that the MySQL instance is
 performing a reverse DNS lookup to resolve the IP address of the
 connecting host.
 
 And if I can't get server root access then that begs the question:

 I don't think that you can.
 
 However, the hosting company should have given you credentials to use
 to log into the database. If your application can log in with those
 credentials, I suggest that you rewrite your code to take
 responsibility for user verification. For example, you could have your
 own user table that gives username and password together with other
 user data you need. (BTW, for security, don't store plain-text
 passwords in your database, rather store hashes (e.g. MD5) of the
 passwords and then use the appropriate function to hash the user input
 and compare with the stored hash).

Re: [PHP] Re: mysql_connect noob question

If that is the case then why does logging in with exactly the same params from 
a UNIX shell work fine? Command line login supposedly would be adding the 
@localhost or @IP_address as well but isn't. Only when I pass the variables to 
the script is that happening.

I am doing exactly as you stated:

 mysql_connect('localhost', $_POST['username'], $_POST['password']);

Except that I am first storing $_POST['username'] in local $user and 
$_POST['password'] in local $pass first and then passing those to 
mysql_connect. And I am connecting to a remote server, not localhost.

I have already documented both the exact HTML and PHP code in this thread and 
so see no need to post it elsewhere.

 Nothing is being added by anything. When you log in to MySQL it takes both 
 the username and the IP address/hostname of the machine you're logging in 
 from and looks those up in the users table. This means that user abc logging 
 in on localhost becomes abc@localhost. User abc logging in from 192.168.0.187 
 becomes abc@192.168.0.187, and is treated as a completely separate user from 
 abc@localhost.
 
 The host comes from your end of the connection. So if you connect on 
 localhost, your end is also localhost. If you connect on the IP address or 
 hostname, your end is the rDNS lookup of your IP address - note that this may 
 be the same address as the one to which you are connecting, but will 
 represent a different user to @localhost as far as MySQL is concerned.
 
 The only thing that may be being added to the variable when the form data is 
 parsed is slashes, and then only if you have magic_quotes_gpc switched on in 
 php.ini. I believe this has already been eliminated as the cause earlier in 
 this thread.
 
 The problem you describe is not possible, so I'm betting your description is 
 missing something. Given a request with POST parameters of username=abc and 
 password=def, the following two lines are equivalent:
 
  mysql_connect('localhost', 'abc', 'def');
  mysql_connect('localhost', $_POST['username'], $_POST['password']);
 
 If this is exactly what you're doing then something very strange is going on. 
 If this is not exactly what you're doing, please narrow your code down to the 
 minimum required to demonstrate the problem and post it somewhere like 
 gist.com then send us the link.
 
 However, a more important question for me is why you are doing this. You say 
 you are aware of the security implications, and that you'll deal with that 
 later, but I question how you're going to deal with it. What exactly are you 
 developing that requires DB credentials to come from a form on a web page?

 I'm wondering, if you can get it to work with the creds in the script,
 why do you have to have them come from a web form at all? What value
 is that providing at all? While it is certainly an interesting
 question as to why it doesn't work, if you have other things in your

Re: [PHP] mysql_connect noob question

One other thing I noted in the FAQ was this:

Dots in incoming variable names
Typically, PHP does not alter the names of variables when they are passed into 
a script. However, it should be noted that the dot (period, full stop) is not a 
valid character in a PHP variable name. For the reason, look at it:

?php$varname.ext;  /* invalid variable name */
?
Now, what the parser sees is a variable named $varname, followed by the string 
concatenation operator, followed by the barestring (i.e. unquoted string which 
doesn't match any known key or reserved words) 'ext'. Obviously, this doesn't 
have the intended result.
For this reason, it is important to note that PHP will automatically replace 
any dots in incoming variable names with underscores.

I should note my user name in this case *is* an email address, however the dots 
in that address are *not* being converted to underscores as mentioned (at least 
not visibly).

What makes you so sure it's not?

It is. I promise you it is. You're not seeing it because you're not getting an
error logging in. Do it on the command line again, but use a username that
doesn't exist and you will see the host it's adding in the error message.

Indeed you are correct:

--port=8904 --user=fakeuser --password=somepassword

Warning: Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user
'fakeuser'@'ip70-162-142-180.ph.ph.cox.net' (using password: YES)

iMac-333:~ glob$

I am doing exactly as you stated:

mysql_connect('localhost', $_POST['username'], $_POST['password']);

Except that I am first storing $_POST['username'] in local $user and
$_POST['password'] in local $pass first and then passing those to
mysql_connect. And I am connecting to a remote server, not localhost.

Side note: why are you putting them in other variables first when you're only
going to use them in that one place? It's a waste of memory. It's a minor
niggle but it's a pet hate of mine.

I am using them in other places - printing them on the response page to
see their values/show the user who logged in, etc.

I have already documented both the exact HTML and PHP code in this thread and
so see no need to post it elsewhere.

And you're saying that when, instead of using $_POST variables you hard-code
the username and password in the script it work? I doubt it.

I can assure you it does. However, I may have found the problem: the
port. As a security measure the BaaS provider appears to have changed
MySQL to a non-standard port. So

On the command line:

sudo mysql --host=instance43490.db.xeround.com --port=8904
--user=realuser --password=realpass

WORKS perfectly - entering the MySQL Monitor.

However, on the same host, same command line:

sudo mysql --host=instance43490.db.xeround.com:8904 --user=realuser
--password=realpass

Does NOT work - returning an error that the host is not found.

So it appears to be the port, which begs the obvious question: is there
a way to tell mysql_connect() to use a different port?

On the command line are you simply doing mysql -u username -p and then entering the
password? In that case it's using localhost. Is MySQL running on the same server as PHP? If so, try
changing the remove server name to localhost in your script. I'm better a magnum of decent
champagne that it works.

See above - I am specifying the host explicitly - as stated in a
previous email the MySQL DB is running on BaaS provider xeround, but the
PHP and forms are running on localhost.

It's very rare (and pretty stupid) for a web host to allow remote servers to
connect to their MySQL instances, unless they have a shared MySQL instance for
all of their customers. Given that you have command line access to the MySQL
server, and can log in without specifying the host, I'm thinking you're trying
to use it in a way they don't allow.

Again this is a test server, the deployment configuration will be different.

You have multiple database users who will need to do this, or just one database 
user? If just one then it makes more sense to hard-code the username and 
password in the script and use something else like HTTP authentication to 
protect the script from unauthorised users. Giving internal database 
credentials to external users is generally a really really bad idea.

Also, consider the time it will take to learn phpMyAdmin (it's simple - 
install, use) against the time it's taking to get your script working. The time 
you've spent developing the script is already sunk so there's no point sinking 
more in an effort to make that already-sunk time worthwhile.

Also, how well tested is your script? I don't know but I can say with absolute 
confidence that phpMyAdmin has been tested far more.

Replace the first parameter to your mysql_connect call with

The idea of sunk time is that it's already been spent, so spending more in an 
attempt to justify the fact you spent it (i.e. to make it work because it's 
already cost you time/money) is daft when you discover a pre-built solution. To 
refuse to investigate it due to a refusal to throw the result of that time away 
is pure stubbornness, a normally expensive path to walk.


I want the script to work - as it should if PHP is 1/2 what it's cracked up to 
be. If not, I'll have to look for another solution (like C which I have been 
using for 20 years).

Am I supposed to care whether you use PHP or not? But sure, let me know how 
much time it takes you to write a web-based MySQL management tool in C. In the 
meantime I'll install phpMyAdmin in five minutes, show it to your client, and 
probably not even charge them for it.

C? Really? Why not assembly language, since the relationship between PHP and C 
is the same as that between assembly and C? Hell, take it all the way to punch 
cards if you want

Re: [PHP] mysql_connect noob question


Thanks for that good suggestion.

I tried that and as expected, the passed variables are coming through 
exactly as expected:


array(3) {
  [user]=
  string(3) joe
  [password]=
  string(11) complacency
  [login]=
  string(5) Login
}

The bottom one seems to be the submit button's tag.

I'm at a loss too. It should work. Replacing all 3 script variables with 
hard-coded values for the login works fine - so I know the host string 
is fine.


Very weird!

I'm at a loss here. The only thing Ican think of is to try something like
this at the top of the script:

?php

error_reporting(-1);
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
header(Content-type: text/plain);
var_dump($_POST);
exit;

?

and see precisely what is being passed in from your form.

First guess is that you don't have privileges for
'user'@'ip70-162-142-180.ph.ph.cox.net', but you may have privileges
for
'user'.

And, what are you using for the $host value? If the script and mysql
are on
the same server, it shouldn't need to be anything other than

'localhost'.

Do your user or password contain spaces, thereby requiring quotes in

your call?

Re: [PHP] mysql_connect noob question


Goog suggestion. The user name is an email address so it does contain @.

Password is all pure lowercase ASCII.

Wonder if the shift-2 is causing the problem?

Pretty much the same goes for me.

It could be charset issue, do your username and password consist of only
ASCII characters, or do they also contain others? If so, then it might be
that your sending these characters in a different charset.

Why are you allowing anyone to connect to your database from a form?


A little OT, but...
What do you mean by this question?  How do you check someone's credentials if 
not by connecting to a db to verify the login?  Cause I'm doing the same kind 
of thing all over the place.  With good practices on validation and such before 
doing my query of course.

I'm pretty sure that's not what tedd meant. The code is logging in to the 
database server using the username and password from the form. There are very 
few legitimate reasons to be doing this, so the question is well worth asking.

-Stuart

Stuart is exactly right.

If you are checking someone's credentials to access your site, such as a user, then 
giving them the keys to the kingdom is a bit of an overkill.

My advice, set up user_id and password fields in a user table for users 
you want to access some portion of your site, here's the code to do that:

http://sperling.com/php/authorization/log-on.php

Where I have said // define your user id here is the place to actually open 
your database and access your user table to gather the correct user_id and password.

I also suggest that when you open the database you only use literals from a 
config.php file ($dbhost,$dbuser,$dbpass) for accessing the actual database and 
then check the user_id and password before giving them authorization to private 
areas.

Keep the private stuff private!

Cheers,

tedd

Already did that. I printed the form values in the PHP script after they

Try printing the $form_user and form_pass values, it might be that it's
just an error elsewhere, maybe field name is different in the html?
Otherwise, it might be you have some php init setting, like magic quotes
that does something with the input data.

Re: [PHP] mysql_connect noob question


Nope, quotes are not visible in the output.

Both the HTML and the script it calls are shown below. They are in 2 
separate files. The variable names in both are user and password. 
The data comes through to the PHP script fine - if I print them I see 
exactly what I typed in the form, but when I pass them to my DB host on 
another server via mysql_connect it give me an error.

You would see the quotes if they were there in the output. There's no
reason why it should not work this way, though I doubt it's safe to do. Can
you show us the rest of the code, including the HTML form?
And exactly what error are you getting? (eg. from mysql_error())
