I'm new here.
Anyway, I did my research on fwrite(), but I couldn't find solution, so i'm asking for help.
What I want is f.e. to add a new line of text after some other specific line.
F.e. I have a .txt file in which there is:
//Users
//Other stuff
//Other stuff2
Now what I'd like to do is be able to add a new user below //Users without touching "Other Stuff" and "Other Stuff 2". So it should look something like this:
//Users
Aneszej
Test321
Test123
//Other stuff
//Other stuff2
What I have so far:
$config = 'test.txt';
$file=fopen($config,"r+") or exit("Unable to open file!");
$date = date("F j, Y");
$time = date("H:i:s");
$username = "user";
$password = "pass";
$email = "email";
$newuser = $username . " " . $password . " " . $email . " " . $date . " " . $time;
while (!feof($file)) {
$line=fgets($file);
if (strpos($line, '//Users')!==false) {
$newline = PHP_EOL . $newuser;
}
}
fwrite($file, $newline);
fclose($file);
test.txt file
//Users
//Something Else
//Something Else 2
But this only writes users to the end of the .txt file.
Thanks a lot everyone for your help! It's solved.
I modified your code, I think follows is what you need, and I also put comment, function below will keep adding new user, you can add condition that to check user exist.
$config = 'test.txt';
$file=fopen($config,"r+") or exit("Unable to open file!");
$date = date("F j, Y");
$time = date("H:i:s");
$username = "user";
$password = "pass";
$email = "email";
$newuser = $username . " " . $password . " " . $email . " " . $date . " " . $time."\r\n"; // I added new line after new user
$insertPos=0; // variable for saving //Users position
while (!feof($file)) {
$line=fgets($file);
if (strpos($line, '//Users')!==false) {
$insertPos=ftell($file); // ftell will tell the position where the pointer moved, here is the new line after //Users.
$newline = $newuser;
} else {
$newline.=$line; // append existing data with new data of user
}
}
fseek($file,$insertPos); // move pointer to the file position where we saved above
fwrite($file, $newline);
fclose($file);
