php5.6是一種常見的編程語言。綠色資源網帶來的為php5.6，具有很大新特性，如：可以使用表達式定義常量、加入hash_equals()函數、新增generators等，用戶下載后體驗下就知道了。

php5.6新特性

主要特性：

Constant scalar expressions.

Variadic functions and argument unpacking using the...operator.

Exponentiation using the**operator.

Function and constant importing with the use keyword.

phpdbg 作為一個交互式集成的調試器 sapI

php://input 現在可以復用，廢棄了 $HTTP_RAW_POST_DATA

GMP 對象支持操作符重載

允許上傳超過 2G 的文件

兼容性方面改進：

Array keys won't be overwritten when defining an array as a property of a class via an array literal.

json_decode() is more strict in JSON syntax parsing.

Stream wrappers now verify peer certificates and host names by default when using SSL/TLS.

GMP resources are now objects.

Mcrypt functions now require valid keys and IVs.

php5.6編譯安裝教程

1、查看當前系統版本

# cat /etc/redhat-release

centos Linux release 7.2.1511 (Core)

2、yum安裝依賴的程序包

yum install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel openssl openssl-devel libxslt-devel

3、安裝libiconv程序包

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.15.tar.gz

tar zxf libiconv-1.15.tar.gz

cd libiconv-1.15

./configure --prefix=/usr/local/libiconv

make

make install

4、配置編譯安裝PHP-5.6.30.tar.gz

wget http://tw1.php.NET/get/php-5.6.30.tar.gz/from/this/mirror

mv mirror php-5.6.30.tar.gz

tar xzvf php-5.6.30.tar.gz

./configure \

--prefix=/usr/local/php \

--with-apxs2=/usr/local/apache/bin/apxs \

--with-mysql=/usr/local/mysql \

--with-pdo-mysql=/usr/local/mysql \

--with-pdo-oci=instanTCLient,/usr,10.2.0.1 \

--with-oci8=instantclient,/usr/lib/oracle/11.2/client/lib \

--with-xmlrpc \

--with-openssl \

--with-zlib \

--with-freetype-dir \

--with-gd \

--with-jpeg-dir \

--with-png-dir \

--with-iconv=/usr/local/libiconv \

--enable-short-tags \

--enable-sockets \

--enable-zend-multibyte \

--enable-soap \

--enable-mbstring \

--enable-static \

--enable-gd-native-ttf \

--with-curl \

--with-xsl \

--enable-ftp \

--with-libxml-dir

make

make install

5、拷貝修改配置文件

cp /usr/local/src/php-5.6.30/php.ini-production /usr/local/php/lib/php.ini

apache增加php支持，修改httpd.conf

在 “AddType application/x-gzip .gz .tgz” 下面增加兩行

AddType application/x-httpd-php  .php  .php3

AddType application/x-httpd-php-source  .phps

在“DirectoryIndex index.html” 后面增加一個index.php

6、測試php環境是否正常

vi index.php

<?php

phpinfo();

?>

7、測試php連接mysql是否正常

vi index.php

<?php

//$link=mysql_connect('localhost','username','password');

$link=mysql_connect('localhost','discuz','discuz') or mysql_error();

if($link){

echo "mysql successful connect php!";

}else{

echo mysql_error();

}

?>

8、LNMP編譯配置

./configure \

--prefix=/usr/local/php \

--with-mysql=/usr/local/mysql \

--with-pdo-mysql=/usr/local/mysql \

--with-xmlrpc \

--with-openssl \

--with-zlib \

--with-freetype-dir \

--with-gd \

--with-jpeg-dir \

--with-png-dir \

--with-iconv=/usr/local/libiconv \

--enable-fpm \

--with-fpm-user=nginx \

--with-fpm-group=nginx \

--enable-short-tags \

--enable-sockets \

--enable-zend-multibyte \

--enable-soap \

--enable-mbstring \

--enable-static \

--enable-gd-native-ttf \

--with-curl \

--with-xsl \

--enable-ftp \

--with-libxml-dir=/usr

9、LNMP啟動php-fpm

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

/usr/local/php/sbin/php-fpm

10、LNMP修改nginx配置文件

#location ~ \.php$ {

#    root           html;

#    fastcgi_pass   127.0.0.1:9000;

#    fastcgi_index  index.php;

#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

#    include        fastcgi_params;

#}

去掉注釋，修改include為fastcgi.conf
