find the creation date of a json file in php

You can use the filectime function in PHP to get the file creation time of a JSON file. Here is an example code snippet:

main.php
$json_file = "example.json";
$creation_time = filectime($json_file);
echo "File creation time: " . strftime('%Y-%m-%d %H:%M:%S', $creation_time);
146 chars
4 lines

In this example, we first specify the JSON file we want to check in the $json_file variable. We then use the filectime function to get the file creation time, which will return a Unix timestamp. Finally, we use the strftime function to format the timestamp into a human-readable date and time. You can adjust the date format as needed by changing the first argument in strftime.
