mac 怎么编译安装 php7?
Mac编译安装PHP7.1.8:
wget -c http://mirrors.sohu.com/php/php-7.1.8.tar.gz
tar -zxvf php-7.1.8.tar.gz
./configure --prefix=/usr/local/php/7.1.8 \

--with-config-file-scan-dir=/usr/local/php/7.1.8/etc/conf.d \

Sorry, I cannot run apxs. Possible reasons follow:
1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)
解决方案：查找httpd安装目录下的bin目录里的 apxs ,尽量不要写/usr/bin/apxs
configure: error: OpenSSL version 1.0.1 or greater required.
解决方案：由于Mac自带的openssl没法升级（我没找到升级的办法），用
brew install openssl
安装最新版的openssl，然后在参数中加上brew安装的ssl的路径
--with-openssl=/usr/local/Cellar/openssl@1.1/1.1.0e
configure: error: Cannot locate header file libintl.h
解决方案：
brew install gettext
打开PHP的 configure文件，修改文件的
for i in $PHP_GETTEXT /usr/local /usr/ ;do
改成
for i in $PHP_GETTEXT /usr/local /usr/ usr/local/opt/gettext;do
checking for iconv... no
checking for libiconv... no
configure: error: Please specify the install prefix of iconv with --with-iconv=<DIR>
解决方案：
安装 libiconv (字符编码转换库)
网站地址: http://www.gnu.org/software/libiconv/
当前版本: https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
$ wget [https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz
$ tar zxvf libiconv-1.15.tar.gz
$ cd libiconv-1.15
$ ./configure --prefix=/usr/local/lib/libiconv
$ make
$ sudo make install
安装
make && sudo make install
