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：
<?php$names = GetFontName('c:/windows/fonts/FZHPJW.TTF');foreach ($names as $name) { if ($name['language'] == 1033) $code = 'utf-16le'; elseif ($name['language'] == 2052) $code = 'utf-16be'; var_dump(mb_convert_encoding($name['name'],'utf-8',$code));}function GetFontName($FilePath) { $fp = fopen($FilePath, 'r'); if ($fp) { //TT_OFFSET_TABLE $meta = unpack('n6', fread($fp, 12)); //检查是否是一个true type字体文件以及版本号是否为1.0 if ($meta[1] != 1 || $meta[2] != 0) return FALSE; $Found = FALSE; for ($i = 0; $i < $meta[3]; $i++) { //TT_TABLE_DIRECTORY $tablemeta = unpack('N4', $data = fread($fp, 16)); if (substr($data, 0, 4) == 'name') { $Found = TRUE; break; } } if ($Found) { fseek($fp, $tablemeta[3]); //TT_NAME_TABLE_HEADER $tablecount = unpack('n3', fread($fp, 6)); $Found = FALSE; for ($i = 0; $i < $tablecount[2]; $i++) { //TT_NAME_RECORD $table = unpack('n6', fread($fp, 12)); if ($table[4] == 1) { $npos = ftell($fp); fseek($fp, $n = $tablemeta[3] + $tablecount[3] + $table[6], SEEK_SET); $fontname = trim($x = fread($fp, $table[5])); if (strlen($fontname) > 0) { $names[] = array ( 'platform' => $table[1], //平台（操作系统） 'language' => $table[3], //字体名称的语言 'encoding' => $table[2], //字体名称的编码 'name' => $fontname //字体名称 ); //break; } fseek($fp, $npos, SEEK_SET); } } } fclose($fp); } return $names;}?> 运行结果：
string(6) "SimHei"
string(5) "SimHe" //貌似有UTF-16LE编码漏字的BUG
string(6) "黑体"
注：如果这里仅需要获取字体名称，可将上述代码进行改进如下：
<?php$names = GetFontName('c:/windows/fonts/FZHPJW.TTF');$newnames = array();foreach ($names as $name) { if ($name['language'] == 1033) $code = 'utf-16le'; elseif ($name['language'] == 2052) $code = 'utf-16be'; array_push($newnames,@mb_convert_encoding($name['name'], 'utf-8', $code));}$font_name=array_pop($newnames);echo $font_name;function GetFontName($FilePath) { $fp = fopen($FilePath, 'r'); if ($fp) { //TT_OFFSET_TABLE $meta = unpack('n6', fread($fp, 12)); //检查是否是一个true type字体文件以及版本号是否为1.0 if ($meta[1] != 1 || $meta[2] != 0) return FALSE; $Found = FALSE; for ($i = 0; $i < $meta[3]; $i++) { //TT_TABLE_DIRECTORY $tablemeta = unpack('N4', $data = fread($fp, 16)); if (substr($data, 0, 4) == 'name') { $Found = TRUE; break; } } if ($Found) { fseek($fp, $tablemeta[3]); //TT_NAME_TABLE_HEADER $tablecount = unpack('n3', fread($fp, 6)); $Found = FALSE; for ($i = 0; $i < $tablecount[2]; $i++) { //TT_NAME_RECORD $table = unpack('n6', fread($fp, 12)); if ($table[4] == 1) { $npos = ftell($fp); fseek($fp, $n = $tablemeta[3] + $tablecount[3] + $table[6], SEEK_SET); $fontname = trim($x = fread($fp, $table[5])); if (strlen($fontname) > 0) { $names[] = array ( 'platform' => $table[1], //平台（操作系统） 'language' => $table[3], //字体名称的语言 'encoding' => $table[2], //字体名称的编码 'name' => $fontname //字体名称 ); //break; } fseek($fp, $npos, SEEK_SET); } } } fclose($fp); } return $names;}?> 则此时可直接输出：
黑体
