从Windows命令行CMD解雇php脚本

I feel like I'm missing something here. php is set up in my system variable PATH. I'm trying to execute a php script from the Window command line, here is my script:

<?php
$file = "test_log.txt";
$content = date("Y-m-d H:i:s") . " - Action logged. 
";
file_put_contents($file, $content, FILE_APPEND);

echo "That worked. I think.";
?>

When called from my browser it works perfectly. A log file is appended with the latest action. However when called from the command line I get the echo, but nothing else happens, no appendment of the log file. See below:

Any ideas?

This should do it:

file_put_contents(__DIR__.'/'.$file, $content, FILE_APPEND);

Reason: Your webserver has a different $_SERVER['DOCUMENT_ROOT'] (and current work directory) than the Command Line Interpreter.
