How can PHP developers troubleshoot issues with displaying images generated from text on different browsers?

To troubleshoot issues with displaying images generated from text on different browsers, PHP developers can check the image output format, ensure proper headers are set, and use appropriate image functions for generating the image. They can also test the image generation code on multiple browsers to identify any specific compatibility issues. 

<?php
// Sample PHP code for generating an image from text
header('Content-Type: image/png');

$text = 'Hello, World!';
$font = 4;
$width = imagefontwidth($font) * strlen($text);
$height = imagefontheight($font);

$image = imagecreate($width, $height);
$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);

imagestring($image, $font, 0, 0, $text, $black);

imagepng($image);
imagedestroy($image);
?>
