PHP获取ttf格式文件字体名的方法示例

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;}?>
