❶ phalcon在php7出后，那点性能优势还有优势吗
Phalcon是一款PHP的框架，全栈的框架，这个PHP7还是PHP5都没动这个奶酪。框架封装了“开箱即用”很多功能。不管php升级什么功能很多场景下还是需要框架的。
PHP好比一个房子，Phalcon好比房子里装修，房子本身为装修提供支撑，装修为住户提供“开箱即用”的功能便利。好了，房子升级了，支持装修可以实现更多“开箱即用”的功能。
如果有一天，PHP真的提供“精装房”，在来比较phalcon是否优势尚在吧。。
PHP7比5也就提升100%的性能，了不得了。
Phalcon比其他的非C扩展框架性能优15-20倍。
❷ PHP7安装intl扩展和linux安装icu
一 PHP intl 是国际化扩展，是ICU 库的一个包装器。所以在安装PHP intl扩展前要先安装ICU库，安装ICU库的具体步骤：:
二 安装intl扩展
1：进入php7.2.5源码：
2：运行：phpize ，找不到命令时，将路径补全：/usr/local/php7/bin/phpize（是php的安装路径），出现如下：
Configuring for:
PHP Api Version: 20100412
Zend Mole Api No: 20100525
Zend Extension Api No: 220100525
3：运行配置
./configure --enable-intl --with-icu-dir=/usr/local/icu/ --with-php-config=/usr/local/php7/bin/php-config
注:前面路径为icu的安装路径，后面路径为php的安装路径。
4：编译扩展：make
5：复制扩展到目标文件夹
cp /user/local/php/php7.2.5/ext/intl/moles/intl.so /user/local/php7/lib/php/extensions/no-debug-non-zts-20170718
注意：也可以find / -name intl.so 查找。
6：设置扩展加入配置文件中：
[intl]
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20170718/"
extension=intl.so
大坑：：：采用phpinfo()时，无法找到配置的intl扩展，说明配置没有生效。。。。。。
原因：在编译php时没有 --with-config-file-path=PATH 指定php.ini路径，默认的路径为/usr/local/php7/lib，只需要将php.ini放入这个默认的路径即可。你也可以安装配置php时加入，如下：
./configure --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-xmlrpc --with-xsl --with-zlib --enable-fpm --enable-bcmath -enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-xml --enable-zip --enable-pcntl --with-curl --with-fpm-user=nginx --enable-ftp --enable-session --enable-xml --with-apxs2=/usr/bin/apxs
访问：index.php中phpinfo()文件。
❸ CENTOS7下PHP7安装PhalconPHP～呢
安装C扩展很简单的，三步走
phpize
configure
make install
即可，
可以看看我写的具体步骤

❹ 如何在php上安装phalcon
下载phalcon 把phalcon.dll 放到相关目录,一般是ext里面 在php.ini中添加 extension=phalcon.dll 重启环境
print_r(preg_grep('/^phalcon/i', get_declared_classes()));

❺ php7版本怎么安装composer
方法/步骤
网络搜索下载 Composer-Setup.exe 安装软件包
下载成功！
准备安装软件，双击软件就可以安装此软件 默认安装装就可以了，并会自动搜索PHP.exe的安装路径。
稍等一会，下载组件
显示此页面表示安装完成！如果报错 就检查 PHP扩展的OpenSSL 有没有打开
验证是否成功。打开win+R 》 cmd 输入 composer,显示如下界面 表示安装成功！
❻ Phalcon入门(一)--安装
Phalcon是一个使用c扩展写的PHP框架, 使用c扩展意味着在运行速度上要优于直接使用php写的框架
因为 Phalcon 是用 c扩展 写的, 所以并不像其他的PHP框架, 比如 laravel , 从git上clone到本地就可以直接运行。而是先要安装phalcon的扩展。
在Mac下安装非常方便, 直接使用homebrew就可以安装了
这里我使用了 php7 , 在 php7 性能较5.x有成倍的提升之后, 使用 php7 再合适不过.
如果你没有安装 php7 , 你也可以使用更低的版本
按照下面的命令显示, 就说明已经安装好 phalcon 了
虽说有了扩展, 我们还是需要一些php的文件才能真正运行 Phalcon
这里我推荐大家安装 Phalcon Tools
可以使用 composer 在全局下安装(我已经在全局环境下安装好composer了)
显示如下内容, 安装成功, 并且可以看到他可以使用的命令
使用Phalcon Tools, 新建一个Phalcon项目就非常简单了
生成的目录如下:
在浏览器中键入 localhost:8008 就可以看到欢迎页面了
