Extension functions to work more comfortably with JSONObject. The idea is to capture nulls instead of Exception or bother with .has function
// WARNING, this code doesn't work, is an example of usage
val json = JSONObject()
json.safeGetString("property")?.let {
// Do awesome things with property value
}

PHP - Add transparent text watermark to an image to make it binary unique
<?php
// Create image resuource, use 'imagecreate*' that you need
$im = imagecreatefromstring($img_string);
imagesavealpha($im, true);
$trans_colour = imagecolorallocatealpha($im, 0, 0, 0, 127); // transparent background
imagefill($im, 0, 0, $trans_colour);
$text_color = imagecolorallocatealpha($im, 0, 0, 0, 126); // almost transparent text color "not visible human eye"
imagestring($im, 1, 0, 0, "UNIQUE_ID", $text_color);
