PHP help (again)

[Guest]

Need a PHP script that does this, It Finds a txt file (localhost:443/forbid/count.txt

 

When the PHP file is Called, it will Get the Value of the Current number lie "1" and Change it to "2", "3", and so on.

 

How can i go about this?

 

Running PHP 7.4 with Apache (and the PHP file will be called from a javascript ajax request)

You can read system files using 'fopen' with the right access flag (r for read, w for write) https://www.w3schools.com/php/php_file_open.asp

[mariushm]

You can use fopen and fread and fclose  or you could just use file_get_contents and file_put_contents

Something like this

 

<?php
// __DIR__  is the folder where this script is saved

$path = __DIR__ .'/forbidden/counter.txt';

$content = file_get_contents($path);
if ($content===FALSE) {
	die("Fail: file $path not found.\n");
}
$value = intval($content);
$value++;

$result = file_put_contents($path,$value);
// output something here if you want to
// header('Content-Type: application/vnd.api+json');
// echo json_encode(array('counter'=>$value, 'success'=>TRUE));

?>
