A quick way to log to a file
This is handy to quickly dump debug information in a script:
file_put_contents('/var/tmp/debug.log', 'File: ' . __FILE__ . ' Line: ' . __LINE__ . " MyVar: $myVar" . "\n", FILE_APPEND);
or maybe:
file_put_contents('/var/tmp/debug.log', 'File: ' . __FILE__ . ' Line: ' . __LINE__ . " MyVar: " . print_r($myVar, true) . "\n", FILE_APPEND);
