Display php output on a txt file Linux command line

If your blacklist.php writes output to standard output, you can run your PHP script like this

php blacklist.php > blacklist.txt

We can do it using file_put_contents

<?php
file_put_contents('blacklist.txt ', file_get_contents('blacklist.php'));  
?>

Another alternative: Use exec()

<?php
exec ('php blacklist.php', $output); 
file_put_contents('blacklist.txt', $output); 
?>

Another alternative:Output redirection to a text file using Command line

In Windows:

C:\xampp\php>php C:\xampp\htdocs\blacklist.php >blacklist.txt

In Linux:

$ php blacklist.php >blacklist.txt

You can use file_put_contents():

file_put_contents('your file', 'your data')

Just run the script and redirect it to the .txt file. Something like

php blacklist.php > blacklist.txt
