Php Script to read write to a file Very handy

<?php

if (isset($_POST['ini'])) 
   //do something
{   


$file_open = fopen("Somefile.txt","w+"); //fopen("Somefile.txt","a+"); to add the contents to file
fwrite($file_open, $_POST['ini']);
fclose($file_open);
}
?>

<form action="<?php $_PHP_SELF ?>" method="POST">
<center><textarea name="ini" COLS=185 ROWS=40>
