这篇文章主要介绍了PHP获取ttf格式文件字体名的方法,结合实例形式分析了php读取ttf字体文件属性的相关操作技巧,需要的朋友可以参考下。

本文实例讲述了PHP获取ttf格式文件字体名的方法，分享给大家供大家参考，具体如下：

1. <?php
2. $names = GetFontName('c:/windows/fonts/FZHPJW.TTF');
3. foreach ($names as $name) {
4. if ($name['language'] == 1033)
5. $code = 'utf-16le';
6. elseif ($name['language'] == 2052) $code = 'utf-16be';
7. var_dump(mb_convert_encoding($name['name'],'utf-8',$code));
8. }
9. function GetFontName($FilePath) {
10. $fp = fopen($FilePath, 'r');
11. if ($fp) {
12. //TT_OFFSET_TABLE
13. $meta = unpack('n6', fread($fp, 12));
14. //检查是否是一个true type字体文件以及版本号是否为1.0
15. if ($meta[1] != 1 || $meta[2] != 0)
16. return FALSE;
17. $Found = FALSE;
18. for ($i = 0; $i < $meta[3]; $i++) {
19. //TT_TABLE_DIRECTORY
20. $tablemeta = unpack('N4', $data = fread($fp, 16));
21. if (substr($data, 0, 4) == 'name') {
22. $Found = TRUE;
23. break;
24. }
25. }
26. if ($Found) {
27. fseek($fp, $tablemeta[3]);
28. //TT_NAME_TABLE_HEADER
29. $tablecount = unpack('n3', fread($fp, 6));
30. $Found = FALSE;
31. for ($i = 0; $i < $tablecount[2]; $i++) {
32. //TT_NAME_RECORD
33. $table = unpack('n6', fread($fp, 12));
34. if ($table[4] == 1) {
35. $npos = ftell($fp);
36. fseek($fp, $n = $tablemeta[3] + $tablecount[3] + $table[6], SEEK_SET);
37. $fontname = trim($x = fread($fp, $table[5]));
38. if (strlen($fontname) > 0) {
39. $names[] = array (
40. 'platform' => $table[1], //平台（操作系统）
41. 'language' => $table[3], //字体名称的语言
42. 'encoding' => $table[2], //字体名称的编码
43. 'name' => $fontname //字体名称
44. );
45. //break;
46. }
47. fseek($fp, $npos, SEEK_SET);
48. }
49. }
50. }
51. fclose($fp);
52. }
53. return $names;
54. }
55. ?>

运行结果：

string(6) "SimHei"

string(5) "SimHe" //貌似有UTF-16LE编码漏字的BUG

string(6) "黑体"

注：如果这里仅需要获取字体名称，可将上述代码进行改进如下：

1. <?php
2. $names = GetFontName('c:/windows/fonts/FZHPJW.TTF');
3. $newnames = array();
4. foreach ($names as $name) {
5. if ($name['language'] == 1033)
6. $code = 'utf-16le';
7. elseif ($name['language'] == 2052) $code = 'utf-16be';
8. array_push($newnames,@mb_convert_encoding($name['name'], 'utf-8', $code));
9. }
10. $font_name=array_pop($newnames);
11. echo $font_name;
12. function GetFontName($FilePath) {
13. $fp = fopen($FilePath, 'r');
14. if ($fp) {
15. //TT_OFFSET_TABLE
16. $meta = unpack('n6', fread($fp, 12));
17. //检查是否是一个true type字体文件以及版本号是否为1.0
18. if ($meta[1] != 1 || $meta[2] != 0)
19. return FALSE;
20. $Found = FALSE;
21. for ($i = 0; $i < $meta[3]; $i++) {
22. //TT_TABLE_DIRECTORY
23. $tablemeta = unpack('N4', $data = fread($fp, 16));
24. if (substr($data, 0, 4) == 'name') {
25. $Found = TRUE;
26. break;
27. }
28. }
29. if ($Found) {
30. fseek($fp, $tablemeta[3]);
31. //TT_NAME_TABLE_HEADER
32. $tablecount = unpack('n3', fread($fp, 6));
33. $Found = FALSE;
34. for ($i = 0; $i < $tablecount[2]; $i++) {
35. //TT_NAME_RECORD
36. $table = unpack('n6', fread($fp, 12));
37. if ($table[4] == 1) {
38. $npos = ftell($fp);
39. fseek($fp, $n = $tablemeta[3] + $tablecount[3] + $table[6], SEEK_SET);
40. $fontname = trim($x = fread($fp, $table[5]));
41. if (strlen($fontname) > 0) {
42. $names[] = array (
43. 'platform' => $table[1], //平台（操作系统）
44. 'language' => $table[3], //字体名称的语言
45. 'encoding' => $table[2], //字体名称的编码
46. 'name' => $fontname //字体名称
47. );
48. //break;
49. }
50. fseek($fp, $npos, SEEK_SET);
51. }
52. }
53. }
54. fclose($fp);
55. }
56. return $names;
57. }
58. ?>

则此时可直接输出：

黑体
