PHP function: Simple picture watermark function code_PHP tutorial

For work needs, I wrote a simple PHP image watermarking function.

2. /*
3. Image watermarking function
4. $imag_url is the path to the image to be watermarked
5. $str is the string to be added to the picture
6. $route is the storage path after watermarking
7. */
8. function watermark($ imag_url,$str,$route) {
9. $type_array=explode(.,$imag_url);
10. $imag_type=$type_array[count($type_array)-1];
11. switch($imag_type) {
12. case gif: $img=imagecreatefromgif($imag_url); break;
13. case jpeg: $img=imagecreatefromjpeg($imag_url); break;
14. case jpg: $img=imagecreatefromjpeg($imag_url); break;
15. case png: $img=imagecreatefrompng($imag_url); break;
16. default: $im g= imagecreatefromgif($imag_url); break;
17. }
18. //Font color
19. $gray = imagecolorallocate($img, 235, 235, 235);
20. $pink = imagecolorallocate($img, 255, 128, 255);
21. /* $fontfile The path of the font, depending on the operating system, can be simhei.ttf (black body), SIMKAI.TTF( Chinese fonts supported by GD*/
22. $fontfile = "C:WINDOWSFontsSIMHEI.TTF";
23. $str = iconv(GB2312,UTF-8,$str); /*Convert gb2312 character set to UTF-8 characters*/
24. imagettftext($img, 30,0, 0, 200, $pink, $fontfile, $str);
25. /* Add Chinese watermark*/
26. imagepng($img,$route);
27. imagedestroy($img);
28. }
29. ?>

I hope the above function can be useful to everyone.
