PHP Fatal error:  Call to undefined function imagettftext()

错误提示是指GD库中缺少freetype库，你装了GD不一定就支持freetype，很多人理解错误，

freetype 不是一个独立的扩展，是附着在GD库上的。

The first step is to install freeType

./configure --prefix=/usr/local/freetype
make && make install

The second step is to install GD including freetype

Switch to the PHP ext source code directory

/opt/php5/bin/phpize
./configure --with-php-config=/opt/php5/bin/php-config --with-jpeg-dir=/usr/local/jpeg/lib --with-freetype-dir=/usr/local/freetype --enable-gd-native-ttf
make && make install

If you need to install gd to support jpeg, please see https://blog.csdn.net/coolpan123/article/details/72916802

If you have not installed gd, write gd.so into php.ini

If you have installed gd before, just restart the php service directly
