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
