How to use inputs in PHP

I have this PHP file, which will write the text to a file:

<?php
$file = 'something.txt';
// Open the file to get existing content
$current = file_get_contents($file);
// Append a new line to the file
$current .= "Some Text\n";
// Write the contents back to the file
file_put_contents($file, $current);
?>

But how do I make it so it takes the text from a input tag instead? I am not very good at PHP, so sorry if it is obvious to you :(

html:

<form action="example.php">
    <input type="text" name="field">
    <input type="submit" value="Submit">
</form>

PHP:

<?php
if (isset($_GET['field'])) {
$file = 'something.txt';
// Open the file to get existing content
$current = file_get_contents($file);

// Append a new line to the file
$current .= "\n".$_GET['field'];

// Write the contents back to the file
file_put_contents($file, $current);
}
?>

or you can use the append flag mentioned in the previous comments.

Assume you have a form in your webpage:

<form action="write.php" method="post">
    <input type="text" name="field">
    <input type="submit" value="Submit">
</form>

Then in your "write.php" should have this:

<?php
    $file = 'something.txt';
    // Open the file to get existing content
    $current = file_get_contents($file);
    // Append a new line to the file
    $current .= $_POST["field"];
    $current .= "\n";
    // Write the contents back to the file
    file_put_contents($file, $current);
?>
