I didn't see this documented anywhere, but I'm trying to use str_replace to delete users
in a peice of code i'm working on, but an error message, saying "Warning: The length of
the needle must not be 0" shows up. This is the code, any ideas?
($todelete is inherited from the previous page, its the number of the user to delete.)
$open = fopen("userlist.txt", "r");
$saved = fread($open, filesize("userlist.txt"));
fclose($open);
str_replace("$username[$todelete]", "", $saved);
$open = fopen("userlist.txt", "w");
fwrite($open, $saved);
fclose($open);
