PHP - Assistance With Preg_match

This topic has been moved to PHP Regex.

ok... I'm still struggling with PHP syntax, my editor's linting keeps flagging a line as incorrect. it's supposed to read as " when d1 minus 1 is less than or equal to d2 with d2 being less than or equal to d1 plus 1" so in other words its supposed to be true if d2 is between d1 minus 1 and d1 plus 1, inclusive. I don't want d2 being the previous number, the same number or the next number relative to d1. The same goes for d3, d4, and d5 (4 and 5 are un coded because why code in errors).

That being said... This isn't exactly my correct goal but I'm not sure how to code what I really want...
Rules
a 3 - 5 digit combo (0 - 99 per digit) whe
1. the numbers are not in order. (1,2,3,4 or 55,56,57,58,59 or 4,3,2,1 or 59,58,57,56,55)
2. no more than 2 numbers in the combo may be the same. (45,12,67,12,78 is ok 17,35,17,24,17 is not)
3. repeat numbers may not occur next to each other (45,12,67,12,78 = valid 45,67,12,12,78 = invalid)

I can't seem to find a good way to test this without the commands I know from other languages like CountIf, Iffn and RandSamp. (those are Ti-Basic commands)

I know "please do it for me" is frowned upon, and hate saying it (I'd rather learn to do it myself), but if anyone can explain how to do this I'd really appreciate it.

Hello all,
I wrote a script that will upload an avatar to a users profile and to do this the user has to get a randomly generated pin that is stored to thier profile info in a MySQL db what i am trying to accomplish with this code is once the form is submitted this code checks the database to see if the ID is there and that the pin matches if so then it continues to upload the file if not it stops displays an error and the upload form. For some reason the script continues to upload even when i input fake values that are not in the DB .... i know its something simple that im jsut over looking so perhaps a fresh set of eyes will help...

I'm pretty new to php... I need a short script that I can place at the top of my web page that does the following:

In theory, a person only be able to access page2.php unless they come directly from page1.php (The message that appear should say you are not authorized to access this page)

I do not want to create login of any kind... Can you help?

thanx in advance!

Alright, so I've been building code in my computer science class (no prior PHP experience before approx. this past week).  We're just importing the first array from a MySQL database, and it's not working for me.  Our teacher included a broken-linked image that apparently tells us how to close the connection, but being unable to see it....I can't.

I'm not sure exactly what's not working, but here's my current code:

Code: [Select]

<html>
<body>
<?php

echo "<h1>This is a test. Does this script insert values?</h1>";

// Connect to the database
$dbc = mysqli_connect('localhost', 'root', 'root', 'myrent-a-movie-final') or die('Error connecting to MySQL server.');

// Build the query
$query = "SELECT * FROM customers";

$result = mysqli_query($dbc, $query) or die('Error querying database.');

//Display Results through Array Loop
While ($row = mysqli_fetch_array($result)) {
echo $row['surname'];
echo $row['given_name'];
echo $row['address'];
echo $row['city'];
echo $row['province'];
echo $row['postal_code'];
echo $row['phone_number'];
echo $row['email'];

// Close the database connection
mysqli_close($dbc);


?>
</body>
</html>




And here is my accompanying error message: "Parse error: syntax error, unexpected $end in Z:\www\mysql_basics\view_data.php on line 32"
