convert a value from json_decode to a string
<p>how do i convert my value from json_decode to string so i can pass in a the string value to check if an email exists here is my code.</p>

<p>my json is in this format:</p>

<pre><code>{email:'test@test.com' }
</code></pre>

<p>PHP:</p>

<pre><code>$var = json_decode($_REQUEST["email"], true);
$result = $membership-&gt;CheckEmailAddress($var); // get $var to become a string
</code></pre>

<p>It looks pretty ugly im just starting php and Im not getting very far aye lol.</p>

<p>jquery:</p>

<pre><code>$('#checkemail').click(function () {
    var json = {
        email: $('#email').val()
    };
    $.post('http://' + location.host + '/buyme/include/getemailaddress.php', {
        'email': 'test@yahoo.co.nz'
    }, function (res) {
        var obj = JSON.parse(res);
        alert(obj.message)
    });
});
</code></pre>

<p>also how do I put my json variable in my $.post function cose thats the value I want to put there</p>
