$im = @imagecreatefromjpeg('poloroid.jpg');
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
//imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
//$text = 'John...';
$fbid = $_POST["id"];

$fb_email =$_POST["email"];
$fb_name=$_POST["name"];
$uploads_dir = 'uploaded_files/';
// Replace path by your own font path
$font = 'verdana.ttf';
//image file name
//$name ="$fbid.png";
$name = $uploads_dir.$fbid.".png"; //this saves the image inside uploaded_files folder
// Add some shadow to the text
imagettftext($im, 20, 0, 25, 126, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 25, 125, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
//imagepng($im);
imagepng($im,$name,9);
imagedestroy($im);

推荐答案
$im = @imagecreatefromjpeg('poloroid.jpg');
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
//imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
//$text = 'John...';
$fbid = $_POST["id"];
$text = $_POST["want"];
$fb_email =$_POST["email"];
$fb_name=$_POST["name"];
$uploads_dir = 'uploaded_files/';
// Replace path by your own font path
$font = 'verdana.ttf';
$font_size = 20;
$angle = 45;
//image file name
//$name ="$fbid.png";
$name = $uploads_dir.$fbid.".png"; //this saves the image inside uploaded_files folder
// Get image Width and Height
$image_width = imagesx($im);
$image_height = imagesy($im);
// Get Bounding Box Size
$text_box = imagettfbbox($font_size,$angle,$font,$text);
// Get your Text Width and Height
$text_width = $text_box[2]-$text_box[0];
$text_height = $text_box[7]-$text_box[1];
// Calculate coordinates of the text
$x = ($image_width/2) - ($text_width/2);
$y = ($image_height/2) - ($text_height/2);
// Add some shadow to the text
imagettftext($im, $font_size, 0, $x, $y+1, $grey, $font, $text);
// Add the text
imagettftext($im, $font_size, 0, $x, $y, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
//imagepng($im);
imagepng($im,$name,9);
imagedestroy($im);
