Shorter example please, if you want us to take a look at your problem, you will need
to take the effort of making an as-short-as possible example.
>From the summary: doesn't return; and/or return $return_value; work?

I've got a problem with a little function in a test script :
I want to return a string value, that exists before returning from the function. And
when I try to get back this string out of the function, the value found is 0 (zero),
and definitly not the one echoed in the function...
You can see below the bugged script (you will have to suppress comments to run it) ,
with some 'echo' to localise the problem, the csv file I tried to analyse, the output
obtained in my browser, and finally, a few lines commenting the problem...
PHP version is 4.04pl1, running with an Apache server, on a NT4 system.
<?
// Here is the script

return "";
else
{$str=addslashes(fgets($f_p,4096));echo
"<BR>getline : $str";return $str;}
// return addslashes(fgets($f_p,4096));
}

a pas d'erreur dans le csv

pages dans le csv...
