How to insert symbols into MySQL database? [duplicate]

Problem :

This question already has an answer here:

I created a page that inserts some data into MySQL database using PHP and jQuery. It's working great but the problem is when I try to insert symbols, for example:

 :) :( :P =D :o ;) :v >:( :/ :'( ^_^ 8) B| <3 3:) O:) -_- o.O >:o :3 (y) 

I get this error:

You have an error in your SQL syntax

Code (that inserts the data into the database)

<script type="text/javascript" src=""></script>
<script type="text/javascript">

      var meesg=$("#reply").val();
      $.post('full.php', {messagge: meesg, from: 'cevin', to: 'calvin'},
      return false;
    function clear() {
      $("#myre:input").each(function() {
<a id="insert" title="Insert Data" href="#">Push into mysql</a>


$query=mysql_query("INSERT INTO `thetable`(`to`,`from`,`message`) VALUES ('$to','$from','$msg')");
    echo "Inserted successfully!";
    echo "An error occurred!"; 

How can I solve this problem of inserting symbols into the database?

Solution :

You need to escape parameters, NOT the whole query (especially you made it after execution, which simply makes no sense at all as it is simply far too late). So this is wrong:

# this is wrong!
$query=mysql_query("INSERT INTO `thetable`(`to`,`from`,`message`) VALUES ('$to','$from','$msg')");

This is better (but still, switch to PDO or at least use mysqli_):

# this is right
$q = sprintf("INSERT INTO `thetable`(`to`,`from`,`message`) VALUES ('%s','%s','%s')",
