PHP How to generate new file txt per day with data - php

Question

I've created data collection for a specific txt file. I need the script to separate records per days.
For example: today is 100 data and i need have a log16Jan.txt file, tomorrow we have 52 data and i need have a log17Jan.txt file?
How i can do that?
<?php
$name = $_POST['name'];
$tekst = "Name: $namee \r\n";
$uchwyt = fopen("log.txt", "a");
fwrite($uchwyt, $tekst);
fclose($uchwyt);
header("Location: http://#/complete.html");
?>

Answer 1

You can get the date using the date() function and add it to the file name, like this:
$name = $_POST['name'];
$tekst = "Name: $name \r\n";
// Adding today's date to the log file
$uchwyt = fopen("log".date("dM").".txt", "a");
fwrite($uchwyt, $tekst);
fclose($uchwyt);
header("Location: http://#/complete.html");

Answer 2

You could use the date() function.
And since you are creating log files you should consider using a log file name that will sort natively in date order in a directory listing. This will make it easier to find a specific log file in a large listing of files. It will also give you more log file cleanup/removal options.
For example:
// 2018-01-16-log.txt
$logFilename = date("Y-m-d") . "-log.txt";
$uchwyt = fopen($logFilename, "a");
UPDATE: per your request about adding a line number before each log line, there are many ways to do this and some depend on your server environment (Linux/Windows). You could read each line from the log and keep a counter. Or you could use a server utility, like Linux wc (Word Count). Here's one way to do it:
<?php
// 2018-01-16-log.txt
$logFilename = date("Y-m-d") . ".log";
echo "Log file = $logFilename\n";
if (! file_exists($logFilename)) {
$count = 0;
} else {
// use Linux wc utility
$count = system("wc -l < $logFilename");
$count = trim($count);
}
echo "Lines = '$count'\n";
$name = $_POST['name'];
if (! $name) {
$name = "NONE";
}
$tekst = "$count. Name: $name \n";
$uchwyt = fopen($logFilename, "a");
fwrite($uchwyt, $tekst);
fclose($uchwyt);
?>
