update your port tree by typing following commands:

# portsnap fetch
# portsnap extract
# portsnap update
			

首次運行 portsnap 需要執行 portsnap extract 這個步驟，之後不再需要,直接運行 portsnap update 即可

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

reinstall

# make reinstall
			

# make deinstall
			

如果用make install clean 安裝，請用 pkg_delete 卸載

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