PHP Increment a counting variable in a text file

Question

This seems simple but I can\'t figure it out.

file_get_contents(\'count.txt\');
$variable_from_file++;
file_put_contents(\'count.txt\', $variable_from_file);         


        

Answer 1

This works for me though

$count = intval(file_get_contents('count.txt'));
file_put_contents('count.txt', ++$count);
echo file_get_contents('count.txt');
