In this tutorial we will create a online notepad script, this will demonstrate how to open and write to a file in PHP.

1. Create a blank .txt file called notepad within the same directory as you will create the PHP script below.
Make sure this file has permission to be wrote to.

2. Copy below and save it as notepad.php

notepad.php

<?php
$file = "notepad.txt"; // The .txt file to store content
 
if (isset($_POST['edit'])) { // Form submitted
    $content = stripslashes($_POST['edit']); // Remove slashes added by magic quotes, if any
    if (file_put_contents($file, $content) !== false) { // Write content to the file
        echo "<p>File updated successfully.</p>";
    } else {
        echo "<p>Error: Unable to update the file.</p>";
    }
}
 
// Read the file content
$fileContent = "";
if (file_exists($file)) {
    $fileContent = file_get_contents($file); // Get file content
    if ($fileContent === false) {
        echo "<p>Error: Unable to read the file content.</p>";
        $fileContent = ""; // Fallback to an empty string
    }
}
?>
 
<form method="post">
    <textarea cols="60" rows="20" name="edit"><?php echo htmlspecialchars($fileContent); ?></textarea><br>
    <input type="submit" value="Update">
</form>
