不能写入文件PHP没有错误

Question

I am trying to write data into a text file from php using fwrite or file_put_contents . Although both fwrite and file_put_contents return 20 indicating Write operation successful and that 20 bytes were written into the file, but i can't find anything in the file. What might be the issue??

• My file is writable.
• PHP is able to find my file.
• I have even made the file wriable in $file_write_handle.

SO what is the problem here??

<?php

$file_name = "user_notes.txt";

$file_write_handle = fopen($file_name,'w');

$data = " i am a disco dancer";

if(file_exists($file_name))
{
    echo "exist";   
}else{
    echo "absent";
}

echo "&nbsp";


if(is_writable($file_name))
{
    echo "writable";
}else {
    echo "cant write";
}

$fw=fwrite($file_write_handle, $data);
echo "fw result" . $fw . "<br/>";

$fpc=file_put_contents($file_name, $data);
echo "fpc result : " . $fpc;
fclose($file_write_handle);

?>

当我在本地服务器上工作并且文件正在写入并存储在服务器而不是本地计算机上时，问题已解决。
