The main issue the user is facing is replacing content in a text field and updating a table in PHP. To solve this issue, you can use PHP to retrieve the updated content from the text field and then update the corresponding record in the database table using SQL queries. 

<?php
// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Retrieve updated content from text field
$newContent = $_POST['new_content'];

// Update table with new content
$sql = "UPDATE your_table_name SET content = '$newContent' WHERE id = your_record_id";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();
?>
