How can I write to the console in PHP?

by

Or you use the trick from PHP Debug to console.

First you need a little PHP helper function

function debug_to_console($data) {
    $output = $data;
    if (is_array($output))
        $output = implode(',', $output);

    echo "<script>console.log('Debug Objects: " . $output . "' );</script>";
}

Then you can use it like this:

debug_to_console("Test");

This will create an output like this:

Debug Objects: Test
