unable to print text on image - php

Question

I am trying to write text on image and displaying that image on browser. I tried below code but it is not working properly. Below code is showing one empty square (no image). Can anyone tell what's wrong I am doing here.
<?php
header('Content-type: image/jpeg');
$jpg_image = imagecreatefromjpeg('images/travel.jpg');
$white = imagecolorallocate($jpg_image, 255, 255, 255);
$text = "This is a sunset!";
imagettftext($jpg_image, 25, 0, 75, 300, $white, $text);
imagejpeg($jpg_image);
imagedestroy($jpg_image);
?>

Answer 1

The problem in your code is this line
imagettftext($jpg_image, 25, 0, 75, 300, $white, $text);
As mentioned in the doc http://www.php.net/manual/en/function.imagettftext.php
you have to pass font file path too
So just change the line
imagettftext($jpg_image, 15, 0, 15, 15, $white, 'Roboto-Bold.ttf',$text);
and put a font file to the folder and it will work.
If you don't want to give the font file replace the line
imagettftext($jpg_image, 25, 0, 75, 300, $white, $text);
With
imagestring($jpg_image,15,15,15,$text,$white);
Your code will be
<?php
header('Content-type: image/jpeg');
$jpg_image = imagecreatefromjpeg('https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQf66Ol6NAa6sdNhDJT0z1fVfTmjPjxAHkopPwExZ9AqHSqNzHP');
$white = imagecolorallocate($jpg_image, 255, 255, 255);
$text = "This is a sunset!";
imagestring($jpg_image,15,15,15,$text,$white);
imagejpeg($jpg_image);
imagedestroy($jpg_image);
?>
This will work for you
