You don't need a strlen() call here, as substr understands count from the
right notation:
$sHTML = substr($sHTML, 0, -1);
... or, with Alex's correction:
$sHTML = substr($sHTML, 0, -2);

[PHP-DB] MySQLi Prepared Statements
Hi I am current trying to migrate an existing system using MySQLi to use PDO and I have a quick question with regards to Prepared Statements. Essentially I'd like to replicate the Prepared Statement functionality of PDO using MySQLi so that I can gradually update all the required pages to use similar function calls, and then swap everything over in one go rather than spending ages on a big rewrite. Using PDO you can pass parameters as an array which are bound to the query. Something like: $stmt = $pdo-prepare(SELECT * FROM Blah WHERE foo = ?); $params = array(SomeValue); $stmt-execute($params) The PDO function execute takes 1 parameter which is an array. There are similar functions in MySQLi such as bind_param and bind_result of which one of the parameters is of type mixed var1 [, mixed ...]. Is it possible to construct an array of this type and pass it to these functions, and if so how? I know is's possible to call these functions with something like: $stmt = $db-prepare(SELECT * FROM Blah WHERE foo = ?); $paramTypes = s; $params = array(SomeValue); $stmt-bind_param($paramTypes, $params[0]); But it seems you cannot pass the array itself using the '' operator.

[PHP-DB] Session don't store after header(Location: ...)
Hi everybody, I have a problem with mysql session handler and redirect.
My situation:
- mysql session handler
- one page is posted to another page, that saves a session variable
and redirect to the first page again.
If I do the redirect the variable is not properly setted, otherwise it's
all ok.
My PHP version is 4.3.10-16
They said me I have to use cookies, but I use this.
I use this code before starting session:
@ini_set('session.use_cookies', true);
@ini_set('session.use_only_cookies', false);
@ini_set('url_rewriter.tags', '');
@ini_set('arg_separator.output', 'amp;');
Can you help me?
bye and thanks in advance

Don't use Header(Location:...). Instead spit back very minimal
javascript that does something like:
script
document.location.href = '.';
/script
That way the cookies that get sent back in the header will take affect.

[PHP-DB] if() and else() help needed
Hi,
I'll admit it, this is damned messy. But I want to learn from the list in
how to sort it out. Than for future refrence I will know...
Now I am running 2 different queries/statements here completely seperate. I
have made the nickname field in the database UNIQUE. So than when I have
this sort of query setup no matter what their will only be one nickname entry
for that user. So when people update their profile a new nickname is not
inserted but it is updated. But I want it all in one PHP call. How do I do
this?
Here is the code:
?
if ($REQUEST_METHOD == POST) {
$usr = . $mysql_user . ;
$pwd = . $mysql_password . ;
$db = . $mysql_database . ;
$host = . $mysql_hostname . ;
$cid = mysql_connect($host,$usr,$pwd);
mysql_select_db($db);
// NOTE that form fields automatically become variables
$sql = update round . $round_number . SET
game1='$game1',game2='$game2',game3='$game3',game4='$game4',game5='$game5',game6='$game6',game7='$game7',game8='$game8',misc='y'
WHERE username='$username';
mysql_query($sql);
echo(Your tips have been
savedbrbr$game1br$game2br$game3br$game4br$game5br$game6br$game7br$game8br.);
}
else {echo(Ooops, something bad happened! Please try again shortly.);}
?
?
if ($REQUEST_METHOD == POST) {
$usr = . $mysql_user . ;
$pwd = . $mysql_password . ;
$db = . $mysql_database . ;
$host = . $mysql_hostname . ;
$cid = mysql_connect($host,$usr,$pwd);
mysql_select_db($db);
// NOTE that form fields automatically become variables
$sql = insert into round . $round_number . SET
game1='$game1',game2='$game2',game3='$game3',game4='$game4',game5='$game5',game6='$game6',game7='$game7',game8='$game8',misc='y',username='$username';
mysql_query($sql);
echo( );
}
else {echo(Ooops, something bad happened! Please try again shortly.);}
?
As you can see 2 PHP calls. What I want is to have it all in one PHP call.
On the update one I deleted the echo statement text. I want the insert one to
have the text that appears and the update text output to say your tips have
been updated...
Of course if the DB is down or something output an error to try again like
already in the else() statements.
The help would be great.
Thanks!

How are you differentiating between the statements?
eg they are logged in, or you check with a database query or ?
You could do something like this:
// check for $_GET['tipid'] - if it's there, we're updating our tips.
// if it's not, then we're adding new tips.
if (isset($_GET['tipid'])) {
$query = UPDATE ..
$success_message = Your tips have been updated;
} else {
$query = INSERT INTO .
$success_message = Your tips have been saved;
}
$result = mysql_query($query);
if ($result) {
echo $success_message;
} else {
echo Problem!!br/;
}

Re: [PHP-DB] if() and else() help needed
Hi,
Yes the user is logged in. The system knows who is tipping by their nickname
and unique id system.
So if I put the update query in the else statement would this be the easy fix?
I use something like a field called tipped in the table, so if they have
tipped it goes to y and if never tipped it's blank. I think it should show
that in the query. Cant remember, I did the scripts 2 or 3 years ago. Just
want to tidy it up.

[PHP-DB] Using OR in a SELECT statement
Newbie MySQL question...
I have a situation where if I don't have a custom value then I must use the
default value. There will always be a default value but there may also be a
custom value.
I could do this with:
select value where id and custom condition
if (EOF) {
select value where id and default condition
if (EOF) {
// no value found for this id - error, return false
}
}
// return value
If I change this to:
select value where id and (custom condition or default condition)
... will I always get the custom value if there is one, or do I have to have
2 selects to be sure that I always get the custom value if there is one? IE
does MySQL consistently read and process the OR statement from left to right
or does it change depending on what's most optimal?
Cheers
Arno
