preg_split — 通過一個正則表達式分隔字符串
array preg_split ( string $pattern , string $subject [, int $limit = -1 [, int $flags = 0 ]] )
通過一個正則表達式分隔給定字符串.
pattern：用于搜索的模式, 字符串形式.
subject：輸入字符串
limit：如果指定, 將限制分隔得到的子串最多只有limit個, 返回的最后一個 子串將包含所有剩余部分.limit值為-1， 0或null時都代表"不限制", 作為php的標準, 你可以使用null跳過對flags的設置.
flags：flags可以是任何下面標記的組合(以位或運算|組合):
PREG_SPLIT_NO_EMPTY：如果這個標記被設置, preg_split()將進返回分隔后的非空部分.
PREG_SPLIT_DELIM_CAPTURE：如果這個標記設置了, 用于分隔的模式中的括號表達式將被捕獲并返回.
PREG_SPLIT_OFFSET_CAPTURE：如果這個標記被設置, 對于每一個出現的匹配返回時將會附加字符串偏移量. 注意: 這將會改變返回數組中的每一個元素, 使其每個元素成為一個由第0 個元素為分隔后的子串, 第1個元素為該子串在subject 中的偏移量組成的數組.
<?php
//使用逗號或空格(包含" ", , , , f)分隔短語
$keywords = preg_split("/[s,]+/", "hypertext language, programming");
?>
使用偏移量：
<?php
$str = 'hypertext language programming';
$chars = preg_split('/ /', $str, -1, PREG_SPLIT_OFFSET_CAPTURE);
print_r($chars);
?>

4.安裝PHP FPM
yum install php55w-fpm
yum install php56w-fpm
yum install php70w-fpm
注：如果想升級到5.6把上面的55w換成56w就可以了。
yum install php56w-fpm

解決方案如下：
VIM /etc/my.cnf
[mysql]
default-character-set=utf8
[client]
default-character-set=utf8
[mysqld]
default-character-set=utf8
init_connect='SET NAMES utf8'
DB腳本：
create database news charset utf8;
CREATE TABLE `news` (
`id` int(11) DEFAULT NULL,
`details` varchar(8192) CHARACTER SET utf8mb4 DEFAULT '',
) ENGINE=MyISAM DEFAULT CHARSET=utf8
`id` int(11) DEFAULT NULL,
`details` varchar(8192) CHARACTER SET utf8mb4 DEFAULT '',
) ENGINE=MyISAM DEFAULT CHARSET=utf8
PHP連接時使用下面的SQL
Class DbUtil {
private static $db;
private static $host='127.0.0.1';
private static $user='root';
private static $pass='xxxx';
private static $dbname='xxxx';
private static $instance = null;
function __construct()
{
$this->dbInit();
}
function dbInit()
{
if(!self::$db)
{
self::$db=new mysqli(self::$host,self::$user,self::$pass,self::$dbname);
if (self::$db->connect_errno)
{
die("Connect failed: %s\n", self::$db->connect_error);
}
self::$db->set_charset("utf8mb64");
}
}
public static function getInstance(){
if(self::$instance==null){
self::$instance=new DbUtil();
}
return self::$db;
}
}
private static $db;
private static $host='127.0.0.1';
private static $user='root';
private static $pass='xxxx';
private static $dbname='xxxx';
private static $instance = null;
function __construct()
{
$this->dbInit();
}
function dbInit()
{
if(!self::$db)
{
self::$db=new mysqli(self::$host,self::$user,self::$pass,self::$dbname);
if (self::$db->connect_errno)
{
die("Connect failed: %s\n", self::$db->connect_error);
}
self::$db->set_charset("utf8mb64");
}
}
public static function getInstance(){
if(self::$instance==null){
self::$instance=new DbUtil();
}
return self::$db;
}
}

通過google，發現下面的解決方案：

插入紅色字部分即可解決， 具體的可以參見文檔中的解釋。
