Mac下安装php扩展mcrypt

1、确定libmcrypt已经安装在本机，如果没安装，先安装这个，安装方法

cd ~/Downloads/libmcrypt-2.5.8
./configure --disable-posix-threads --enable-static
make
sudo make install

2、找到自己php版本，下载php完整安装包

cd ~/Downloads/php-5.5.14/ext/mcrypt
phpize
./configure
make
cd modules
sudo cp mcrypt.so /usr/lib/php/extensions/no-debug-non-zts-20121212/

  如果phpize出现如下错误：

grep: /usr/include/php/main/php.h: No such file or directory
grep: /usr/include/php/Zend/zend_modules.h: No such file or directory
grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory
Configuring for:
PHP Api Version:
Zend Module Api No:
Zend Extension Api No:
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

需要执行，注意下面mac版本号

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/
Developer/SDKs/MacOSX10.11.sdk/usr/include /usr/include

如果 4：打开php.ini

sudo vi /etc/php.ini

添加如下代码：（注意no-debug-non-zts-20121212版本号，如果不清楚可以前往/usr/lib/php/extensions/查看）

extension=/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so

  重启apache即可
