hi,
I got following function to check if a specific string already exist in a
specific file but it doesn't work.
I not even see the string: "valid file-pointer" but I don't know why. May
anyone help me please?
Thank you!
function string_exists($email)
{
$file=fopen ($blacklist,"r");
if ($file)
{
echo "valid file-pointer";
while(!feof($file))
{
$buffer = fgets($file,4096);
echo $buffer."<br>n";
if ($buffer==$email)
{
echo "already string exists!<br>n";
return true;
}
else
{
echo "not yet!<br>n";
}
}
return false;
}
}

$blacklist has not been defined, or it is outside the variablescope. I'm
guessing you've defined $blacklist elsewhere in the code. The easiest thing
to do is define $blacklist global. Just insert the line
global $blacklist;
at the first line of the funtion, before $file=fopen(.... That way the
function "sees" the variable as well, and therefore knows what to open.
Didn't check the rest of the code. Try with that and tell us what happens.
