How do I get fwrite() to not print to the page? - php

Question

I'm using fwrite() to write a file, however, every time it runs, it prints all of the information to the webpage it's on and writes to the file, too. I'd rather it not echo it to the page.
Alright, I've retrieved the code. Here it is:
fwrite($data_file, "Confirmation Data: \r\n\r\n Song: " . $input_song . "\r\nFile1: " . $file_var1 . "\r\nFile2: " . $file_var2 . "\r\nFile3: " . $file_var3 . "\r\nFile4: " . $file_var4 . "\r\nExplanation Text: " . $input_explanation);
Whenever I run this, it outputs everything in the second place of fwrite() onto the page, so it outputs the follow onto the page, except with the variables replaced for their values:
Confirmation Data: \r\n\r\n Song: " . $input_song . "\r\nFile1: " . $file_var1 . "\r\nFile2: " . $file_var2 . "\r\nFile3: " . $file_var3 . "\r\nFile4: " . $file_var4 . "\r\nExplanation Text: " . $input_explanation

Answer 1

You should post your code, so we can follow it but most probably you are also echoing out the code as HTML in your PHP file and this is why it prints out on the screen.

Answer 2

You said your information is being echoed and not written to file. Perhaps you are using echo instead of using file related functions. However, without access to your code, I can only post how to write information to a file in PHP:
<?php
error_reporting(E_ALL);//display all errors
ini_set('display_errors', true);
$filename = "testfile.txt";//the name of your output file
$fh = fopen($myFile, 'w');//create a filehandler - fh) and open the file in write mode
$string = "ABCDEFGH\n";//test string to write to the file
$myvar = fwrite($fh, $string);
$string = "IJKLMNO\n";//update the string variable with new data
fwrite($fh, $string);//write more data - can be repeated ad -infinitum
fclose($fh);//finally, close the file
But, if you truly want definitive answers, post your code so that we may be able to help you.
