PHP:
<?php

function create_image($user){
global $fontname;
global $quality;
$file = "covers/".md5($user[0]['name'].$user[1]['name'].$user[2]['name']).".jpg";
// if the file already exists dont create it again just serve up the original
//if (!file_exists($file)) {
// define the base image that we lay our text on
$im = imagecreatefromjpeg("pass.jpg");

// this defines the starting height for the text block
$y = imagesy($im) - $height - 365;
// loop through the array and write the text
foreach ($user as $value){
// center the text in our image - returns the x value
$x = center_text($value['name'], $value['font-size']);
imagettftext($im, $value['font-size'], 0, $x, $y+$i, $color[$value['color']], $fontname,$value['name']);

<input type="text" value="<?php if(isset($_POST['email'])){echo $_POST['email'];}?>" name="email" placeholder="Email"><br/>
<input name="submit" type="submit" class="btn btn-primary" value="Update Image" />
