Question

Im working with a foreign API and im trying to get a fix on what all its sending to my file with the GET method.

How can i output something like print_r($_GET) to a file so i can read what all its sending?

Writing to a file:

You could use file_put_contents() to create the file with your output. This function will accept a string, or an array, which releases you of the burden to convert your array into a writable-format.

file_put_contents("myget.txt", $_GET);

As stated in the comments, this option isn’t ideal for multidimensional arrays. However, the next solution is.

Maintaining format:

If you’d like to maintain the print_r() formatting, simply set the second parameter to true to return the value into a variable rather than outputting it immediately:

$output = print_r($_GET, true);
file_put_contents("myget.txt", $output);
