Unable to create a file on ubuntu using php

Question

I am trying to create a simple text file on my server using PHP.

I have given 777 permission to the folder still I am unable to create the file it gives following error:

Warning: fopen(demo.txt): failed to open stream: No such file or directory in /var/www/code/fcreate.php on line 6 unable to create

The PHP code is as follows:

<?php

ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);

fopen('demo.txt','r') or die('unable to create');

?>

From the docs ~ mode 'r' - Open for reading only; place the file pointer at the beginning of the file. — Phil

fopen should create the file if it does not exists . But the file is not being created when i see in the folder — ashwinbhy

There are several modes that will attempt to create the file if it does not exist and you can see them all on the fopen manual page. Hint ~ r is not one of them — Phil

You're trying to read a file because of that flag you're using r (read).

The flag r stands for:

'r' Open for reading only; place the file pointer at the beginning of the file.

You can use a+ read/write. If the file does not exist, attempt to create it.

$handle = fopen('demo.txt','a+') or die('unable to create');

If you want more clarity. Kindly visit the manual for more details. (Check out the modes part).

fopen('demo.txt','w') or die('unable to create'); instead of demo.txt i need to give full path '/var/www/demo.txt' this solved my error
