macbook pro 下安装php7 limxml2 checking whether libxml build works... no

环境：

是用brew 安装的libxml2 

用brew安装前最好更新一下

# brew update

sudo brew install libxml2

==> Downloading https://homebrew.bintray.com/bottles/libxml2-2.9.3.el_capitan.bo

######################################################################## 100.0%

==> Pouring libxml2-2.9.3.el_capitan.bottle.tar.gz

==> Caveats

This formula is keg-only, which means it was not symlinked into /usr/local.

OS X already provides this software and installing another version in

parallel can cause all kinds of trouble.

Generally there are no consequences of this for you. If you build your

own software and it requires this formula, you'll need to add to your

build variables:

    LDFLAGS:  -L/usr/local/opt/libxml2/lib

    CPPFLAGS: -I/usr/local/opt/libxml2/include

==> Summary

?  /usr/local/Cellar/libxml2/2.9.3: 276 files, 9.8M

# cd php-7.0.6

# ./configure --with-libxml-dir=/usr/local/Cellar/libxml2/2.9.3/

通过--with-libxml-dir指定libxml2的安装位置

Thank you for using PHP.

brew安装PHP提示Cannot find OpenSSL's ?

是因为php 调用的openssl是系统的，需要指定：

--with-openssl-dir=/usr/local/Cellar/openssl/1.0.2h/  --with-openssl=/usr/local/Cellar/openssl/1.0.2h/
