PHP Imagestring() Function

Imagestring( ) function is another inbuilt PHP function mainly used to draw a horizontal string. The function works using the x and y-axis, used to set coordinates for the starting point from where the picture has to be drawn. The origin coordinates ( 0, 0 ) are in the browsing window's top-left corner. We can set the coordinates accordingly from the origin to get the resulting picture according to our needs.

<body>
<? Php
   // to define the size of the image
$image= imagecreate(400, 300);
// to define the background color of the image
$background-color= imagecolorallocate($image, 0, 155, 0);
  
// to define the text color of the image

// Prints all character of string 
Imagestring ( $image , 6 , 180 , 100 , ? HELLO WORLD ? , $ text ? color ) ;

header('Content-type: image/png');
imagepng($image);
?>
</body>
</html>

Output

Here in this program, we have declared various variables like $image to define the size of the image that we require, $background color to define the color of background we require, $text color to define the color of text we require. We have used the image string ( ) function to declare the complete string we want to display as an image. To display the output of the image, we have used an inbuilt PHP command header and imagepng to display on the browser.
