The first anatomically modern humans, known as Homo sapiens, evolved in Africa about 300,000 years ago. However, human-like species have existed for millions of years, with the earliest known human ancestor being Sahelanthropus tchadensis, which lived in Chad about 7 million years ago. Over time, different human species have evolved and gone extinct, leading to the emergence of modern humans. The exact timeline of human evolution is complex and constantly evolving as new discoveries are made.

Sahelanthropus tchadensis is a scientific name given to a species of extinct hominid that lived about 7 million years ago in what is now Chad. The name "Sahelanthropus" comes from the location where the fossil was found, Sahel, which is a region in Africa that stretches from the east to west coast. "Tchadensis" refers to the country where the fossil was discovered, Chad. The species is important because it is one of the oldest known human-like species, and its discovery has contributed to our understanding of human evolution.

If you want to read all items from a MySQLi database table and save them into a text file, you can modify the previous example code like this:

// Connect to the database
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

// Select all data from the table
$sql = "SELECT name, email, phone, message FROM contact_form";
$result = $conn->query($sql);

// Check if any results were returned
if ($result->num_rows > 0) {
  // Create a string with the data for all rows
  $data = "";
  while ($row = $result->fetch_assoc()) {
    $data .= "Name: " . $row["name"] . "\n";
    $data .= "Email: " . $row["email"] . "\n";
    $data .= "Phone: " . $row["phone"] . "\n";
    $data .= "Message: " . $row["message"] . "\n\n";
  }

  // Write the data to a file
  $filename = "contact_data.txt";
  $file = fopen($filename, "w");
  fwrite($file, $data);
  fclose($file);

  echo "Data saved to file: " . $filename;
} else {
  echo "No results found.";
}

// Close the database connection
$conn->close();

In this modified code, we're selecting all rows from the contact_form table and creating a string with the data for each row using a while loop. We're also adding an extra newline character \n between each row to make the text file more readable.

Note that if you have a large amount of data in the table, you may want to consider paginating the results or limiting the number of rows returned to avoid memory issues. You can use the LIMIT and OFFSET clauses in the SQL query to achieve this.

Again, make sure to properly sanitize and validate user input to prevent SQL injection attacks and other security vulnerabilities, and handle any errors that may occur when reading from the database or writing to the file.

Here's a basic PHP code to create a customer form with input fields and save the data to a file:

HTML Form Code:

<form method="post" action="save_data.php">
  <label for="name">Name:</label>
  <input type="text" name="name" id="name" required>
  
  <label for="email">Email:</label>
  <input type="email" name="email" id="email" required>
  
  <label for="phone">Phone:</label>
  <input type="text" name="phone" id="phone" required>
  
  <input type="submit" value="Submit">
</form>

PHP Code to Save Data to a File (save_data.php):

<?php
// Get form data
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];

// Define file name and location
$file = "customer_data.txt";

// Open file in append mode
$fp = fopen($file, "a");

// Write customer data to file
fwrite($fp, $name . "," . $email . "," . $phone . "\n");

// Close file
fclose($fp);

// Redirect user back to form
header("Location: customer_form.php");
?>

This code will save the customer data to a file called "customer_data.txt" in the same directory as the PHP script. The data will be saved in CSV format, with each line containing the name, email, and phone number of a single customer.

Note: Be sure to validate and sanitize the user input to prevent security issues like SQL injection or cross-site scripting (XSS).

Here's an example PHP code that reads the customer data from the "customer_data.txt" file and displays it in a table format using your custom layout:

<?php
// Define file name and location
$file = "customer_data.txt";

// Read file into array
$data = file($file);

// Output table header
echo "<table>";
echo "<tr><th>Name</th><th>Email</th><th>Phone</th></tr>";

// Loop through data and output table rows
foreach($data as $line) {
  $fields = explode(",", $line);
  echo "<tr>";
  echo "<td>" . $fields[0] . "</td>";
  echo "<td>" . $fields[1] . "</td>";
  echo "<td>" . $fields[2] . "</td>";
  echo "</tr>";
}

// Output table footer
echo "</table>";
?>

In this code, we first define the file name and location, and then use the file() function to read the contents of the file into an array.

We then loop through the array and split each line into fields using the explode() function. We output the data in a table format using your custom layout, with each row containing the name, email, and phone number of a single customer.

You can customize the HTML code inside the loop to match your custom layout.

Yes, a disc storage lock can be picked open, although the level of difficulty will depend on the specific lock and the skill of the person attempting to pick it. Disc storage locks are designed to be difficult to pick, but they are not completely impervious to picking.

Disc storage locks typically have a series of pins inside them that must be aligned in a certain way in order for the lock to be opened. A skilled lock picker can use specialized tools, such as picks and tension wrenches, to manipulate the pins and get them into the correct position to open the lock.

However, picking a disc storage lock can be time-consuming and require a lot of skill and practice, so it's not something that can be easily done by someone who is not experienced in lock picking. Additionally, there are other methods of bypassing a lock, such as using a key, using a bypass tool, or drilling the lock, that may be easier or faster than picking the lock.
