I know i'm a few years late lol. But this is for anyone who still has come across this issue.
I ran across this issue today. Everything I did confirmed fwrite was only happening once, but yet
somehow, the data in the file said it was happening twice.
Then I thought maybe the script is being called twice. So I manually called the script via the
command line, and it only happened once. However, when I access the script by loading the webpage,
it happens twice.
Skipping to the end, I dumped the _SERVER contents, and found the second write came from a second
request browsers automatically make to /favicon.ico
The issue happened because I and as some others may have a fallback/ReWrite setup, so any
non-existent script request are re-routed to another file like index.php

No way... i tested again, the same code, the same code that was giving me troubles... I tested the
g_i_ivanov's code, and both are working! This must be a joke... I didn't change php
version, I didn't change the code... This can't be true :/...
I'm sorry for wasting your time. If I see any weird behavior, I will let you know it.

Not reproducible.
Try providing a working example script, the one in the report doesn't work.

I have the same problem:
Windows XP Professional SP3, Apache/2.2.14, PHP 5.2.13 (cli)
code:
------------------------------------------
$fp = fopen("d:/Projects/test/logs/testfile.txt", "a");
fwrite($fp, date('c') . " - Sample text" . PHP_EOL);
fclose($fp);
result:
------------------------------------------
2010-05-31T10:36:37+03:00 - Sample text
2010-05-31T10:36:37+03:00 - Sample text

Description:
------------
I'm having troubles with fwrite() function. It is writing twice a text I just need to write
once. I searched in google for the same problem, and I found the same bug reported here : http://bugs.php.net/bug.php?id=21916, and here : http://bugs.php.net/bug.php?id=16225, but neither
of both was solved.
This is how it writes into the file :
"First
Second
Hello world!
Hello world!
Third"
As you can see, the string "hello world!" is writed twice, and that should not happen.
Also, and this is weird, the line fwrite($op, $lastLine); prints the text correctly, just once...
Test script:
---------------
$file = "test.txt";
$string = "Hello world!\r\n";
$op = fopen($file,"r+");
$exp = explode("\n", fread($op, filesize($file)));
$lastLine = end($exp);
fseek($op, -strlen($lastLine), SEEK_END);
fwrite($op, $string);
fwrite($op, $lastLine);
fclose($op);
Expected result:
----------------
The text should be writed just once.
