[SOLVED] PHP Dynamic text file creation

Issue

I have this code

$ext = ".txt";
$filename = $namef.$ext;
if(!file_exists($filename))
{
$file = fopen($filename,"w");
fwrite($file, $privatekey);
fclose($file);
chmod($file,0777);
}

$namef is any name that gets input into this program. However when I run this, I keep getting:

Unable to access (name_of_file).txt in something.php
Warning: fopen(name_of_file.txt) [function.fopen]: failed to open stream: No such file      or directory in something.php 
Warning: fwrite(): supplied argument is not a valid stream resource in ./something.php on line 79

Warning: fclose(): supplied argument is not a valid stream resource in ./something.php on line 80

Warning: chmod() [function.chmod]: Unable to access in ./something.php on line 81

May i know if dynamic text file name creation is possible?

Thank you

Solution

Write this simple code no need of if statements. it will open the file in read write mode and create automatically if it doesn,t exist or open a file if it already exists.

$ext = ".txt";
$filename = $namef.$ext;
$file = fopen($filename,"w+");
fwrite($file, $privatekey);
fclose($file);
chmod($file,0777);
