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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51640&edit=1
