Hi ; I need to just take all the uıser id's from a CSV file. All the fields are seperated by ";" and in front of the id's there is a line break (a rectangle). Does anyone know how to ? ??

Use the file and explode functions.

http://www.php.net/file
http://www.php.net/explode

or fgetcsv.

http://www.php.net/fgetcsv

The latter has a user provided function that might work for you:

but I am trying to just take the id. I mean the algorithm is going to be like :
for every line take the value until the first comma and if the value is integer store it in somewhere..
Is it possible ??

preg_match_all() is what you want:
http://www.php.net/manual/en/function.preg-match-all.php
--the function returns an array of matches so will do all the work for you but you will have to break the ice with regular expressions
--regular expression can look for matches only at the beginnings of lines like you want but you have to set flags to do that.

a good online regular expression tutorial I use:

I still cannot find the beginning of the line function ? Does anyone have the code for that ?
