If you are just appending ", hello" to your file (As that seems like what you are doing from the code above), Try using "a" as the file mode instead of "r+", and simply writing ", hello" to your file (Which should appear at the end.)

Best of luck,

You didn't say what you expected to happen. But this looks like it will just add one line to the end of the file (last input line plus the word hello).

What happened? And what did you expect?

First Thank you for your helpfull reply,
My purpose is ( to open a txt file,and read all the words, give these words to a variable named $words,then write new words which got from a form to the txt file,and add $words to the end of the txt file!)to add new word in the front of a txt file, I'll be glad if you give me a simple example!

See if this does what you want. There's still a small chance that two visitors at the same time will both try to write the file.

$filename="data.txt";

$words='';
$myfile=fopen($filename,"r");
while(!(feof($myfile))) $words .= fgets($myfile,225);
$myfile=fopen($filename,"w");
fputs($myfile,"$words,hello");
fclose($myfile);
