I was trying to query a mysqli database to display part of my blog articles on my main page using php. It output a messy character as shown on the link. www.myimcm.com (unwanted commas and stuffs like that. The simple code for this was:

 $q ="SELECT SUBSTRING_INDEX(post_content,' ',130) AS post,(post_title) AS title,ID AS id FROM wp_posts WHERE post_type='post' ORDER BY post_date DESC LIMIT 1";
$r = @mysqli_query ($dbc, $q); // Run the query.

if ($r) { // If it ran OK, display the records.
    echo '<h2>LATEST FROM OUR GUIDES</h2>'; 
// Fetch and print all the records:
while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) {
     echo"<p class='title'>". ($row['title'])."</p>";
     echo nl2br($row['post']);

echo '<a href="http://guides.myimcm.com/wp"> Continue reading</a>';

}
    mysqli_free_result ($r); // Free up the resources.  

} else { // If it did not run OK.

    // Public message:
    echo '<p class="error">The are no latest from our blog. We apologize for any inconvenience.</p>';

    // Debugging message:
    echo '<p>' . mysqli_error($dbc) . '<br /><br />Query: ' . $q . '</p>';

} // End of if ($r) IF.
mysqli_close($dbc); // Close the database connection.

Answer 1

use utf-8 encoding in your webpages. Use this code in your head section.

 header("Content-Type: text/html; charset=utf-8");

Answer 2

Your page claims to be encoded in UTF-8, but that is not true. It contains the following octets: 85 , 91 , 92 , a0 which (on their own) are not valid UTF-8. They are probably from one of the Windows-125x character encodings, such as Windows-1252 .

You need to set up your database to use the correct character encoding for the Database, Table, and connection. See the MySQL manual and PHP manual for details.
