fwrite

[Anon]

    $fp = fopen("file.txt", "a+");                            
    $fwrite = ("sup", "w");
    fclose($fp);

I am trying to write a $ to a file.. which is at the moment sup.

I want it to add a line each time it is submitted, but now it wont even write to it at all.

Any ideas?

thanks

For starters:

$fp = fopen("file.txt", "a+");
$fwrite = ("sup", "w");

This is not ok; if the file fails to open, you can't write to it. Instead, say

if ($fp = fopen("file.txt", "a+"))
   {
   fwrite(...);
   fclose($fp);
   }
else
   echo "Something went wrong: $php_errormsg";

Next, you don't really need "a+" mode unless you expect to rewind or seek to earlier parts of teh file and read from there. Just plain "a" mode is all you need.

Finally, and most interestingly, you're not calling fwrite. Instead, you're assigning something to a variable called $fwrite. Instead, call the function in the manner described on the manual page:

fwrite($fp, "something\n");

$file_name = "yourfile.txt";
$file_pointer = fopen($file_name, "a");
fwrite ($file_pointer, "what ever your wish to print");
fclose($file_pointer);

try this simple code it work's fine with me.

sigh
What did Kirk just say about checking wether the fopen worked?

$file_name = "yourfile.txt";
if ($file_pointer = fopen($file_name, "a"))
{
fwrite ($file_pointer, "what ever your wish to print");
fclose($file_pointer);
}
else
{
echo 'Could not open file '.$file_name;
};

Make everything as simple as possible, but no simpler!

That sounds quite simple...
