這篇文章主要介紹了PHP獲取ttf格式文件字體名的方法,結(jié)合實例形式分析了php讀取ttf字體文件屬性的相關(guān)操作技巧,需要的朋友可以參考下

本文實例講述了PHP獲取ttf格式文件字體名的方法。分享給大家供大家參考，具體如下：

<?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));
    //檢查是否是一個true type字體文件以及版本號是否為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], //平臺（操作系統(tǒng)）
    'language' => $table[3], //字體名稱的語言
    'encoding' => $table[2], //字體名稱的編碼
    'name' => $fontname //字體名稱
            );
            //break;
          }
          fseek($fp, $npos, SEEK_SET);
        }
      }
    }
    fclose($fp);
  }
  return $names;
}
?>

運行結(jié)果：

string(6) "SimHei"
string(5) "SimHe" //貌似有UTF-16LE編碼漏字的BUG
string(6) "黑體"

注：如果這里僅需要獲取字體名稱，可將上述代碼進行改進如下：

<?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));
    //檢查是否是一個true type字體文件以及版本號是否為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], //平臺（操作系統(tǒng)）
    'language' => $table[3], //字體名稱的語言
    'encoding' => $table[2], //字體名稱的編碼
    'name' => $fontname //字體名稱
            );
            //break;
          }
          fseek($fp, $npos, SEEK_SET);
        }
      }
    }
    fclose($fp);
  }
  return $names;
}
?>

則此時可直接輸出：
