MAC上的平台是XAMPP，自带的版本低。
我用的是XAMPP MAC版本
一 本地php环境配置
$which php$php－v ｜ phpxampp php PASH=" ／applications／xampp／bin/:$PASH"sudo nano vi~/.bash_profile export PATH="/Applications/XAMPP/bin:$PATH"ctrl O 保存 ctrl X 退出
注：
httpd.conf.
applications/xampp/etc/httpd.conf.
二 Laravel5
安装
php 配置修改完以后
1 安装composer的几种方案
——官方的方案：
curl -sS https://getcomposer.org/installer | php -- --install-dir=bin --filename
——我的方案 ：下载composer.phar 最新版本
然后
$ mv composer.phar /usr/local/bin/composer
运行
——其他方案
在Mac OS X下也可以使用homebrew安装：
brew tap josegonzalez/homebrew-php
brew install josegonzalez/php/composer
不过通常情况下只需将composer.phar的位置加入到PATH环境变量就可以，不一定要全局安装。
声明依赖
在项目目录下创建一个composer.json文件，指明依赖，比如，你的项目依赖 monolog：
{
"require": {
"monolog/monolog": "1.2.*"
}
}
三 安装laravel5中遇到的问题
$composer global require "laravel/installer=~1.1"
Changed current directory to /Users/macbookair/.composer
./composer.json has been created
Loading composer repositories with package information
The "https://packagist.org/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:

？？？？？？
三问题的分析和调试
PHP 5.6 的最新功能
$ php -r "print_r(openssl_get_cert_locations());"
显示的内容如下
Array
(
[default_cert_file] => /Applications/XAMPP/xamppfiles/share/openssl/cert.pem
[default_cert_file_env] => SSL_CERT_FILE
[default_cert_dir] => /Applications/XAMPP/xamppfiles/share/openssl/certs
[default_cert_dir_env] => SSL_CERT_DIR
[default_private_dir] => /Applications/XAMPP/xamppfiles/share/openssl/private
[default_default_cert_area] => /Applications/XAMPP/xamppfiles/share/openssl
[ini_cafile] =>
[ini_capath] =>
)
红色部分表示没有文件
修正方法：通过brew从新装一下openssl
$brew install openssl

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl/certs
…………………………………………….
最后在php.ini 中加入
openssl.cafile=/usr/local/etc/openssl/cert.pem
sh-3.2# composer global require "laravel/installer=~1.1"
Changed current directory to /var/root/.composer
./composer.json has been updated

OK
