checking for previous user

[Anon]

When a user registers to create an account, I want the script to check my text file to see if the username is already listed there. If it is report an error, if its not continue registering. I also want to do the same thing with the email. If the username is available but the same email address is found, it wont' register it.

"One account per email"

Can someone please send me the code to do these things?

Thanks!

The text file looks like this

username|password|email|full name
username|password|email|full name

it can go on forever...

Open the textfile,
Read each line
Explode each line to get the username/email
Compare to the new input.
If match, close the file and report an error.

This will take ages!
This is really a job for a database!

what's the code to do this?

I'm not sure how to read it in, explode it and compare it...

I'm not sure if you actually deserve a reply when you are demanding source code...

However...

Take a look at the file() function
www.php.net/manual/function.file.php
It reads a file into an array.

Then take a look at each() which returns keys and values from an array.
http://www.php.net/manual/function.each.php

Then check out list() which is a language construct used to assign multiple variables in one statement (for example multiple return values).
http://www.php.net/manual/function.list.php

You will have to parse out the values so a good look at explode() will be neccesary.

Now, check out the pseudocode previously posted and to your you as a programmer and implement it 😉

I'm sure someone can, but this isn't the appropriate place to ask. Try posting an ad in the phpbuilder jobs section.

I will do it for $20 😉
