How can a user choose a file to be read in PHP code?

To allow a user to choose a file to be read in PHP code, you can use a file input field in a form. This form will allow the user to select a file from their local machine, which can then be processed by the PHP code. Once the file is uploaded, you can use PHP functions such as file_get_contents() or fopen() to read the contents of the file. 

<form action="read_file.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Read File">
</form>

<?php
if(isset($_FILES['file'])) {
    $file = $_FILES['file']['tmp_name'];
    $content = file_get_contents($file);
    echo $content;
}
?>
