Imap, Check User
If imap_open(string) doesn't work i gets an error message.
I don't want that message. I tried to get around the problem by using:

if (imap_open(string) == false) {
echo("Go back and try again!");
} else {
header("Loacation: show_inbox.php");
}

but I still got that error message if the openstring's not correct.

Check If A User Is Logged In
I'm trying to create a login app and I need to check if a user is logged in already or not and the send them to the aproriate page. Is this possible? If so, how do I do it?

Check If User Has Authenticated
I've got a web site that has a mix of public and private sections.
When you first come to the site, the final option on the menu is
"Private" which forces an authentication and then gives you an
expanded menu that includes all the private sections of the site.
What I'd like to do is give users the proper menu ("public only" or
"public and private") depending on whether they have authenticated
with the site.

I thought of just checking for $_SERVER["REMOTE_USER"] or
$_SERVER["PHP_AUTH_USER"] but if you are on a public page, those don't
exist whether or not you have authenticated with the private sections.
I was hoping not to have to deal with sessions or cookies but is that
the only option I have? Or is there some value somewhere that will
tell me that a user has authenticated and that is available (to PHP)
even in the public areas?

How To Check If User Is Logged In In VBulletin With PHP
Anybody knows how to check if a visitor in vBulletin with a PHP script?

Check User/password On Included Pages
if i have itlike tihs: login.php checks the username and sets $_SESSION[] variables login to 1 username to username and password to password:

then it takes you to main.php. all that one does is include navigation and all the content. if the link is clicked. it also checks if the user's logged in. what i am wondering is.

all the pages that are to be included. is it ok not to check username/password on them and only check if the variable $inc exists. that variable is set on main.php, plus the include pages dont have session_start() on them. will that stop people from accessing them individually? they cant fake variables right?

Check If User Is On Mobile Device Or If Flash Is Disabled?
I'm currently researching the use of flash in web pages and realise that many portable devices such as mobile phones or pdas can't run flash.

Is there a way of checking if they're on a mobile device or if flash is disabled using php?

I've looked into it and it seems like it's only possible to check if flash is disabled using javascript and even then it's highly unreliable.

How To Check If A Database Exists?
I'm writing a class to create Databases, and I'll also make one to create Tables. But how do I check if a database already exists? just by checking if you can select it like so:

// Select the MySQL database
$this -> db_select = mysql_select_db ($this -> database);

// Test the database selection
if (!$this -> db_select) { return false; }

(don't mind the "$this" it's coded in OOP but I didn't think I would need to put it in the OOP forum for this simple example) So is this the right way to check it or is there another way?

How To Check A Checkbox Based On Database Value
I have saved a "Y" or "N" in the database field, based on a Checkbox setting in the "Add Contact" screen.

Check To See If A Variable Exists In An SQL Database
I am working on a project. I want to safegaurd against a user entering a number into the database multiple times. So what i want to do is run a query and check the users entry against the database, and then return an error if it exists. Here is how i thought it would work

The script would take the Text Field posted and asign it a variable

$var = $POST_['textfld'];
Then i thought it might work if i were to say

$var2 = mysql_query("SELECT item FROM table WHERE var = '$var'");

Then i could have a statement similar to

if { $var = $var2
echo "Number already entered into Database";
}
else echo "Thank You";

I thought that would be a good way to make it work, but its not working so far, any suggestions?

Retrieving Database Info Based On User
I'm still quite new to php and mysql but I have been unable to figure this out. I'm attempting to display a specific row and column from a mysql database based on the user.

$result = mysql_query("SELECT fbleague FROM users WHERE username = $_SESSION[username]");
fbleague is the column
users is the table
username is the primary key column
$_SESSION[username] is the username variable

Then later I try to display it with

echo "You are in league $result ";

I know $_SESSION[username] is set correctly because I can display that with no problems.

What Is Indexing In Mysql And How It Will Be Useful And How We Can Retrieve Database Content Easily From A Database Table Containing About 5lakhs Datas
I need to select data from a database table containing huge amount of
data. Now I am storing data using one primary key and I am just using
simple select statement, and this process gives me the output but it is
taking long to execute the query. As much I had heared I want to use

Mysql Check.
<?php
$sql = "SELECT * FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1";
mysql_query($sql) or die ("Couldn't execute $sql: " . mysql_error());
if (mysql_query($sql) == NULL){
echo "No such song";
} else {
$sql2 = "DELETE FROM songs WHERE Title = '".$_POST['songtitledelete']."' LIMIT 1";
mysql_query($sql2) or die ("Couldn't execute $sql: " . mysql_error());
}
?>

That should make sense? I want to check if the song is there. Otherwise it always says "Song Deleted". I want something to detect whether it's there before deleting the row.

When i run it now i dont see "No such song" when i enter an invalid song name.

Convert User Entered Date And Time To Unix Timestamp Before Inserting To Database
How do you convert a user inputted date to a unix timestamp before
insterting it into your database? I have a form, with a textfield for

together and converted to one Unix Timestamp and then inserted to the

of the standard 0000-00-00 format of MYSQL so that I can do better
calculations and queries.

Check Contents Of Mysql Table
ok, so now that I've figured out how to allow users to upload files (with help!) I'm trying to run a script that will check the name of the uploaded file and determine if that file name already exists in a specific mysql table. Here's what I've got so far:

$filename = $_FILES['uploadfile']['name'];

$query = "SELECT * FROM $table";
$result = mysql_query($query, $conn);

while ($checkfile = mysql_fetch_assoc($results)){
$existfile = $checkfile['filename'];
}//end while

if ($existfile == $filename){
print "A file with that name already exists.";
}
else {
some script that adds the file info to $table
}

Now, this combination of while and if statements will only catch a match with an already existing filename if the already existing filename was the last one to be updated. I've tried adding the if and else statements into the while statement but then the file info gets added to the table multiple times. Does anyone have any ideas? Am I even making any sense?

Sanity Check: L10N, PHP, And MySQL
I am currently working on a multi-lingual site that allows users to switch
back and forth between languages per page. Static elements, such as links
and headings, are handled nicely by 'gettext' and 'setlocale()' dynamic
content, including form elements (country/city/category names), comes from
DB tables indexed by id/lang key pairs.

So far, so good. However, what's a good way to store and display a bit
more 'generic' content (ie., date; time; zip; phone #s) depending on
locale setting? Ideally, such values should be stored generically as INT,
TIME, DATE, TIMESTAMP, etc; and, after retrieval from the DBMS, formatted
according to locale.
