PHP获取ttf格式文件字体名的方法示例

<?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));
