PHP7达到最高性能的修改配置方案

PHP7性能提示了但如果想提得更高我们是需要进行一些参数配置修改的，下面我们一起来看一篇关于PHP7达到最高性能的修改配置方案，具体的如下所示。

PHP7已经发布了, 作为PHP10年来最大的版本升级, 最大的性能升级, PHP7在多放的测试中都表现出很明显的性能提升, 然而, 为了让它能发挥出最大的性能, 我还是有几件事想提醒下.

PHP7 VS PHP5.6

1. Opcache

记得启用Zend Opcache, 因为PHP7即使不启用Opcache速度也比PHP-5.6启用了Opcache快, 所以之前测试时期就发生了有人一直没有启用Opcache的事情. 启用Opcache非常简单, 在php.ini配置文件中加入:

zend_extension=opcache.so
opcache.enable=1
opcache.enable_cli=1"
2. 使用新的编译器

使用新一点的编译器, 推荐GCC 4.8以上, 因为只有GCC 4.8以上PHP才会开启Global Register for opline and execute_data支持, 这个会带来5%左右的性能提升(Wordpres的QPS角度衡量)

其实GCC 4.8以前的版本也支持, 但是我们发现它支持的有Bug, 所以必须是4.8以上的版本才会开启这个特性.

3. HugePage

我之前的文章也介绍过: 让你的PHP7更快之Hugepage , 首先在系统中开启HugePages, 然后开启Opcache的huge_code_pages.

以我的CentOS 6.5为例, 通过:

$sudo sysctl vm.nr_hugepages=512
分配512个预留的大页内存:

$ cat /proc/meminfo  | grep Huge
AnonHugePages:    106496 kB
HugePages_Total:     512
HugePages_Free:      504
HugePages_Rsvd:       27
HugePages_Surp:        0
Hugepagesize:       2048 kB
然后在php.ini中加入:

 opcache.huge_code_pages=1
这样一来, PHP会把自身的text段, 以及内存分配中的huge都采用大内存页来保存, 减少TLB miss, 从而提高性能.

4. Opcache file cache

开启Opcache File Cache(实验性), 通过开启这个, 我们可以让Opcache把opcode缓存缓存到外部文件中, 对于一些脚本, 会有很明显的性能提升.
在php.ini中加入:

opcache.file_cache=/tmp
这样PHP就会在/tmp目录下Cache一些Opcode的二进制导出文件, 可以跨PHP生命周期存在.

5. PGO

我之前的文章: 让你的PHP7更快(GCC PGO) 也介绍过, 如果你的PHP是专门为一个项目服务, 比如只是为你的Wordpress, 或者drupal, 或者其他什么, 那么你就可以尝试通过PGO, 来提升PHP, 专门为你的这个项目提高性能.

具体的, 以wordpress 4.1为优化场景.. 首先在编译PHP的时候首先:

$ make prof-gen
然后用你的项目训练PHP, 比如对于Wordpress:

$ sapi/cgi/php-cgi -T 100 /home/huixinchen/local/www/htdocs/wordpress/index.php >/dev/null
也就是让php-cgi跑100遍wordpress的首页, 从而生成一些在这个过程中的profile信息.

最后:

$ make prof-clean
$ make prof-use && make install
这个时候你编译得到的PHP7就是为你的项目量身打造的最高性能的编译版本.

对于拟虚空间我们肯定没有操作服务器的权限此时要备份数据库我们可以集成在网站后台来操作，下面一起来看一篇关于PHP实现MySQL数据库备份的源码教程，具体的如下所示。

下面是一个php数据库备份的源代码，大家也可以根据自己的需求进行修改。

<?php
// 备份数据库
$host = "localhost";
$user = "root"; //数据库账号
$password = ""; //数据库密码
$dbname = "mysql"; //数据库名称
// 这里的账号、密码、名称都是从页面传过来的
if (!mysql_connect($host, $user, $password)) // 连接mysql数据库
{
 echo '数据库连接失败，请核对后再试';
    exit;
}
if (!mysql_select_db($dbname)) // 是否存在该数据库
{
 echo '不存在数据库:' . $dbname . ',请核对后再试';
    exit;
}
mysql_query("set names 'utf8'");
$mysql = "set charset utf8;\r\n";
$q1 = mysql_query("show tables");
while ($t = mysql_fetch_array($q1))
{
    $table = $t[0];
    $q2 = mysql_query("show create table `$table`");
    $sql = mysql_fetch_array($q2);
    $mysql .= $sql['Create Table'] . ";\r\n";
    $q3 = mysql_query("select * from `$table`");
    while ($data = mysql_fetch_assoc($q3))
    {
        $keys = array_keys($data);
        $keys = array_map('addslashes', $keys);
        $keys = join('`,`', $keys);
        $keys = "`" . $keys . "`";
        $vals = array_values($data);
        $vals = array_map('addslashes', $vals);
        $vals = join("','", $vals);
        $vals = "'" . $vals . "'";
        $mysql .= "insert into `$table`($keys) values($vals);\r\n";
    }
}
 
$filename = $dbname . date('Ymjgi') . ".sql"; //存放路径，默认存放到项目最外层
$fp = fopen($filename, 'w');
fputs($fp, $mysql);
fclose($fp);
echo "数据备份成功";
?>

如果使用的是thinkphp可以使用下面代码来备份mysql数据库

<?php
 // www.111cn.net
class BaksqlAction extends CommonAction {
 
    public $config = '';                                                        //相关配置
    public $model = '';                                                         //实例化一个model
    public $content;                                                            //内容
    public $dbName = '';                                                        //数据库名
    public $dir_sep = '/';                                                      //路径符号
 
    //初始化数据
 
    function _initialize() {
        parent::_initialize();
        header("Content-type: text/html;charset=utf-8");
        set_time_limit(0);                                                      //不超时
        ini_set('memory_limit','500M');
        $this->config = array(
            'path' => C('DB_BACKUP'),                                           //备份文件存在哪里
            'isCompress' => 0,                                                  //是否开启gzip压缩      【未测试】
            'isDownload' => 0                                                   //备份完成后是否下载文件 【未测试】
        );
        $this->dbName = C('DB_NAME');                                           //当前数据库名称
        $this->model = new Model();
        //$sql = 'set interactive_timeout=24*3600';                             //空闲多少秒后 断开链接
        //$this->model>execute($sql);
    }

                //获取文件创建时间
                $fileTime = date('Y-m-d H:i:s', filemtime($path . '/' . $value));
                $fileSize = filesize($path . '/' . $value) / 1024;

加密解密对于学习php的同学来讲有时会用到了特别是通过url传输或api时都会有一套加算算法了，下面来看公用的php加密解密的例子。

加密解密

//Hex(Hex(Md5((原文+密钥).getBytes(“utf-8”))).getBytes(“utf-8”))
function String2Hex($string){
    $hex='';
    for ($i=0; $i < strlen($string); $i++){
        $hex .= dechex(ord($string[$i]));
    }
    return $hex;
}

function Hex2String($hex){
    $string='';
    for ($i=0; $i < strlen($hex)-1; $i+=2){
        $string .= chr(hexdec($hex[$i].$hex[$i+1]));
    }
    return $string;
}

// example:

$hex = String2Hex("test sentence...");

$data = array(
    'appId' => 'SHAN-GUO-CHI-BI',
    'data' =>'{"appId":"SHAN-GUO-CHI-BI","cardNo":"6006012000000001"}',
    'sig'=>'4331443139334331313645464642444544364334343742374236364335454243',
);

$key = '111111111111111111111111';

$data['sig'] = String2Hex(strtoupper(md5($data['data'] . $key)));

例子

PHP 转换输出字符串为 Hex Oct
通过下面代码，可以把PHP输出的字符串换行为16进制和8进制。

<?php
$str = "http://www.111cn.net";
$lixiphp = ”;
for($i = 0; $i < strlen($str); $i++) {
  if ($i % 2 == 0) {
    $lixiphp .= ‘\x’.base_convert(ord($str[$i]), 10, 16);
  }
  else {
    $lixiphp .= ‘\\’.base_convert(ord($str[$i]), 10, 8);
  }
}
echo $lixiphp;
?>

通过上述代码，把字符串 "http://www.111cn.net" 转换为"\x68\164\x74\160\x3a\57\x2f\142\x6c\157\x67\56\x6c\151\x78\151\x70\150\x70\56\x63\157\x6d"

PHP实现来基数位字符串转换十六进制，偶数位字符串转换为八进制。

下图是ASCII码表，可以简单的核对10进制、8进制和16进制与127常用字符的关系。

 

支付接口现在有第三方的支付接口也有银行的支付接口了，今天我们来介绍php版本银联支付接口开发实例了，这个我估计可以帮助到不少的朋友的哦。

银联支付，首先要注意二重要的部分：

PHP运行环境是5.4.18以上
开了扩展openss

开发手册上面的列子只做参考，因为基本都是错的。你可以试着去官网下一个demo。。。注意现在银联开发，没有测试密钥提供，只能在正式环境开发【20151219】

下面是我用ThinkPHP编写的一个支付类

银联支付应该是算比较简单的！！

感觉银联的支付接口比支付宝的还简单好用了，当然每个考虑到的东西不一样哦，上面只是开个玩笑的哦

微信公众号服务号可以实现许多的功能如果我们要发红包那么必须要服务号了，否则无法实现此功能了，下面我们来看一篇关于php版的微信公众号接口发红包程序代码例子吧，具体的如下所示。

1. 微信商户号，已申请微信支付
2. 微信商户号主体下面的微信公仔号
