write output of print_r in a txt file. PHP
php
Solution
`print_r()` has a second parameters that if passed as `TRUE` returns the output as a string.
$output = print_r($data, true);
file_put_contents('file.txt', $output);
You could even cosinder using `var_export` function, as it provides better information about data types. From `print_r` you can't tell if the variable is NULL of FALSE, but `var_export` lets use see exactly the data type of a variable.
