lookup data from text file and removing a line problem

cobusbo · February 25, 2015

Hi I've created a scricpt thats devided into 4 parts

Part 1

Inserting info into a text file

Part 2

Removing info from the text file

Part 3

Lookup the value stored within the text file if it match show form if not don't show form

Part 4

Broadcasting the message

I'm currently experiencing a problem with Part 2. Every time I click the button it doesn't remove the info needed after a few clicks the whole unique.csv file gets removed

I assume HTTP_X_MXIT_USERID_R contains the users username? If so then try doing a simple str_replace

$raw = file_get_contents($source) or die("Cannot read file");
$raw = str_replace("$mxituid\n", "", $raw);
file_put_contents($source, $raw);

I see no need for regex for removing a user from the file.

Yes it recall the username - and still the username is found inside the unique.csv file. Selecting the option to remove it have no effect. What I'm basicly trying to achieve is to give users the opportunity to add and remove their usernames from my unique.csv Because part 4 of my script will be using the unique.csv file to keep sending pop up messages to the people on the unique.csv file. So I'm not sure what I'm doing wrong in my script because the broadcasting option aint working neither.
