update your port tree by typing following commands:

# portsnap fetch
# portsnap extract
# portsnap update
			

首次运行 portsnap 需要执行 portsnap extract 这个步骤，之后不再需要,直接运行 portsnap update 即可

# cd /usr/ports/lang/php5
# make install
			

reinstall

# make reinstall
			

# make deinstall
			

如果用make install clean 安装，请用 pkg_delete 卸载

# cd /usr/ports/lang/php5
# make config
# make install
