Sending data changed when it received

I have one textarea. I am sending the value of text area 

<textarea class="php" name="codeguru"></textarea></div>
<div class="hint">This code is editable. Click Run to execute.</div>
<input type="submit" value="Run" />

through $ajax method

$.ajax({
    type: 'GET',
    url: 'exec.php',
    dataType: 'JSONP',
    data: {
        code: code
    },
    success: function (data) {},
    jsonpCallback: 'mycallback',
    error: function (xhr, ajaxOptions, thrownError, err, textStatus) {

    }
});

Problem : When i am send a data like echo 'sanjay'; it is converted to echo \'sanjay'.

I have same implemented it on localhost and on cpanel. This works fine on localhost but not perfectly on cpanel. Any suggestions or ideas will be appreciated.

You should URL Encode it before the AJAX and decode it server side. This happens alot to me with specific chars in JSON strings, I usually URL encode it :

Meaning :

    $.ajax({
    type: 'GET',
    url: 'exec.php',
    dataType: 'JSONP',
    data: {
        code: encodeURIComponent(code)
    },
    success: function (data) {},
    jsonpCallback: 'mycallback',
    error: function (xhr, ajaxOptions, thrownError, err, textStatus) {

    }
});

And in server side :

$code = urldecode($_POST['code']); // or rwaurldecode, not sure

Try sending code with / and " and see how it responds, because I had issues with those as well, if it does try adding slashes to quotes, etc. I use the following function, but you can modify it to suit your needs :

function addslashes( str ) {
    return (str + '').replace(/[\\"]/g, '\\$&').replace(/\u0000/g, '\\0');
}
