I know it is fine run on other environment,
I think it must be something wrong at a special environment.

my php configuration is:

./configure --prefix=/usr/local/php7  --with-config-file-path=/etc/php7/ --with-config-file-scan-dir=/etc/php7/conf.d  --enable-fpm --enable-phpdbg  --enable-phpdbg-webhelper  --with-zlib=/usr/local/opt/zlib --with-zlib-dir=/usr/local/opt/zlib --enable-bcmath --with-curl --with-libxml-dir=/usr/local/opt/libxml2  --with-gd --with-xpm-dir=/usr/x11 --with-jpeg-dir=/usr/local/opt/jpeg  --with-png-dir=/usr/local/opt/png    --with-freetype-dir=/usr/local/opt/freetype  --enable-gd-native-ttf    --enable-mbstring  --with-mcrypt=/usr/local/opt/mcrypt  --with-mysqli   --with-pdo-mysql  --enable-mysqlnd   --enable-pcntl    --enable-soap  --enable-sockets   --enable-sysvmsg  --enable-sysvsem  --enable-sysvshm --enable-wddx  --with-xmlrpc   --with-pcre-dir   --with-pear   --with-readline=/usr/local/opt/readline  --with-iconv=/usr/local/opt/libiconv --with-gettext=/usr/local/opt/gettext   --with-icu-dir=/usr/local/opt/icu4c  --enable-intl  --with-openssl  --with-openssl-dir=/usr/local/opt/openssl

That, or it's something wrong with your code. Or how you're viewing the output.
Run exactly what you posted from the CLI. Or run it in a browser but do a View Source of the page.
