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
