Using PHP’s image functions we can able to add text on a image or a background programmatically using PHP.In this tutorial we will be designing a webform through which you enter the text and create an image file that will have the submitted text.

Final Output:

Things needed: Background image and font file

Here I have used the chunkyfive open type font to style the text.Different fonts can be used by adding otf file.

Code:

<?php<br />
// Select the background image<br />
$imgPath = 'background.png';<br />
$im = imagecreatefrompng($imgPath);

//Font colour<br />
$white = imagecolorallocate($im, 255, 255, 255);

// Path to font file<br />
$font = 'Chunkfive.otf';

// Write it<br />
imagettftext($im, 35, 0, 95, 100, $white, $font, '15.7 MBPS');<br />
imagettftext($im, 25, 0, 95, 200, $white, $font, 'Average Internet speed in');<br />
imagettftext($im, 25, 0, 125, 200, $white, $font, 'South Korea');

// Output to browser<br />
header('Content-Type: image/png');

//write the final image to a file<br />
imagepng($im,"output.png");<br />
imagedestroy($im);

?><br />

 

imagecreatefrompng: Function will read the png file.

imagecolorallocate: Set the colour of the text.

imagettfbbox: This function will create a bounding box inside which we will be writing the text.For this X and Y coordinates have to be provided

imagettftext: Actual image that writes the text to the image.

Design a html form that accepts text to be added on the image.

      It depends on how you implement the third party image hosting site.If you are using any API then check if they offer the image url after upload completes.
