SETUP

From your terminal,

• run git clone to copy this repo to your local working directory.
• start the server php -s 0.0.0.0:[port-number]. For example, php -S 0.0.0.0:2021.

If you clone the repo into your already established application server which are being used to run PHP based apps, you don't need to start the server as instructed above.

HOW TO LOG ERRORS TO FILES

Being consulted from the thread, I simplify here how to log errors to files.

$data = array('shopid' => 3,'version' => 1, 'value' => 1);  //here $data is dummy variable

$log_file = $_SERVER['DOCUMENT_ROOT']."/errors-".date("Y-n-j").".log";

error_log(print_r($data,true), 3, $log_file);

// In $data we can mention the error message and create the log
    

Under the root directory of your PHP scripts, there is a log file named errors-2021-11-18.log which was created on 18/11/2021.
