how to replace image in php?
<p>I used this code for replacing an image, but the image is not uploaded in upload folder, but the database is updated.  I need to replace the image.</p>

<pre><code>&lt;?php
require("header.php");

$patientid = $_POST['patientid'];
$pname = $_POST['pname'];
$fname = $_POST['fname'];
$address = $_POST['address'];

if(!$pname || !$address) {
    echo "&lt;center&gt;";
    echo "Fillup required fields&lt;br&gt;&lt;br&gt;";
    echo "&lt;/center&gt;";
}
else {
    $ran2 = $patientid;
    $new_name2 = $ran2."b";
    $new_file_name2 = $new_name2."."."jpg";
    $path = "./members/".$new_file_name2;

    $copied = move_uploaded_file($_FILES['img_name']['tmp_name'], $path);

    if ($copied) {
        $sql = mysql_query("UPDATE info_store 
        SET pname='$pname', fname='$fname', address='$address', image1='$new_file_name2'
        WHERE patientid='$patientid'");
        return true;
    }
    else {
        echo "&lt;center&gt;&lt;h3&gt;There are An Errors In Uploading!&lt;/h3&gt;&lt;/center&gt;";
        return false;
    }
}
?&gt;
</code></pre>
