Introducing the comparison between php7 and php5

Recommendation (free):PHP7

When PHP7 came out, it was said to be much faster than the old version. Times, the speed and efficiency of various open source frameworks or systems running on PHP7 have increased several times. Anyway, both the media and developers are fanning the flames, no, they should be full of praise.
I will just watch you show off quietly and say nothing.

Generally, I am the last person to upgrade mobile phone systems because I don’t want to step into the trap. After all, systems like iOS and Android will have bugs, not to mention the most hacked languages in the world.

The time has come today to see if PHP7 is as awesome as the legend says.

Install two PHP versions

http://php.net/ There is already the latest version of PHP7, you can download it yourself.
In order to test the performance of PHP5 and PHP7 (PHP6 has been abandoned, distressed 1s), I installed two php versions in different directories.

The installation process is skipped. Regardless of source code installation or package management tool installation, just remember your own path.

PHP7:

# /usr/local/php7/bin/php -vPHP 7.1.5 (cli) (built: May 13 2017 23:36:41) ( NTS )Copyright (c) 1997-2017 The PHP GroupZend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

PHP5:

# /usr/bin/php -vPHP 5.6.30 (cli) (built: Jan 19 2017 22:31:39)Copyright (c) 1997-2016 The PHP GroupZend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

Environment description: In order to ensure the best test effect, this test is conducted directly in the production environment, which is closer to the real situation.
Operating system: CentOS 7.2 64-bit
Basic configuration: 1 core 1GB 1Mbps

Competition between PHP7 and PHP5

1. Pure php script test

##vim test.php

$arr = array();for ($i = 0; $i < 500000; $i++) {$arr[$i] = $i;}$tmp = array();foreach ($arr as $i) {if ($i % 2 == 0) {$is_exists = array_key_exists($i, $arr);if ($is_exists) {array_push($tmp, $i);}}}

PHP5 version test:

time /usr/bin/php test.php real 0m0.301suser 0m0.239ssys 0m0.050s--------------------------time /usr/bin/php test.phpreal 0m0.310suser 0m0.241ssys 0m0.054s--------------------------time /usr/bin/php test.phpreal 0m0.289suser 0m0.238ssys 0m0.050s

PHP7 version test :

time /usr/local/php7/bin/php test.phpreal 0m0.087suser 0m0.063ssys 0m0.024s-------------------------------------time /usr/local/php7/bin/php test.phpreal 0m0.106suser 0m0.073ssys 0m0.033s--------------------------------------time /usr/local/php7/bin/php test.phpreal 0m0.083suser 0m0.061ssys 0m0.022s

It can be seen from the data that the performance of php7 has been improved by 3 to 4 times through a simple PHP script test.

2.php database operation test

First we create a user table:

Table: test_userCreate Table: CREATE TABLE `test_user` (`uid` int(11) NOT NULL AUTO_INCREMENT,`name` char(100) NOT NULL DEFAULT '',PRIMARY KEY (`uid`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

Insert a piece of data into the test_user table:

insert into test_user (uid,name) values (1,"dada");MariaDB [test]> select * from test_user;+-----+------+| uid | name |+-----+------+| 1 | dada |+-----+------+

Create the database test script test_db.php and ensure that both your PHP versions have the PDO extension installed.

/usr/bin/php -m|grep pdopdo_mysqlpdo_sqlite/usr/local/php7/bin/php -m|grep pdopdo_mysqlpdo_sqlite

My two PHP versions have PDO installed (do not use the php_mysql extension anymore, it is outdated, PHP7 has been completely abandoned, and mysqli is not recommended).

Next we write a script through PDO to test the performance comparison of select execution 500,000 times:

$host = "yourHost";$user = "yourUser";$pass = "yourPass";$db = "test";$port = 3306;try{$dbh = new PDO("mysql:host=$host;dbname=$db", $user, $pass);echo "Connected
";}catch (Exception $e){echo "Unable to connect: " . $e->getMessage() ."
";}$sql = "select SQL_NO_CACHE * from test_user;";$tmp = array();for ($i=1; $i<=500000; $i++) {$ret = $dbh->query($sql);foreach ($ret as $row) {$tmp['id'] = $row['id'];$tmp['name'] = $row['name'];}}

PHP5 test test_db.php:

time /usr/bin/php test_db.phpreal 0m48.396suser 0m11.149ssys 0m3.998sreal 0m51.447suser 0m11.800ssys 0m4.395sreal 0m51.517suser 0m11.733ssys 0m4.439s

PHP7 test test_db.php:

real 0m47.900suser 0m9.875ssys 0m4.130sreal 0m46.977suser 0m9.760ssys 0m3.983sreal 0m50.010suser 0m10.268ssys 0m4.307s

This time the script executed 500,000 queries. The user execution time of the script executed by PHP7 is almost one second less than that of PHP5! It's one second less, not one millisecond.

3.PHP framework test

• thinkphp

Domestic affirmation It is the first choice thinkphp framework, choose the latest thinkphp5. I downloaded the thinkphp5.0.9 version directly from the official website.

• (1) Framework entry test

Test under PHP5:

time /usr/bin/php ./public/index.phpreal 0m0.036suser 0m0.026ssys 0m0.010sreal 0m0.038suser 0m0.026ssys 0m0.012sreal 0m0.041suser 0m0.032ssys 0m0.009s

Test under PHP7:

time /usr/local/php7/bin/php ./public/index.phpreal 0m0.027suser 0m0.021ssys 0m0.005sreal 0m0.027suser 0m0.018ssys 0m0.009sreal 0m0.025suser 0m0.023ssys 0m0.002s

In the entrance test, you can see that there is not much difference between PHP and PHP7, but PHP7 is still slightly faster.

• (2) Framework logic test

  Reuse the logic of the first step at the framework entrance:
  

PHP5 version:
      

      
time /usr/bin/php ./public/index.phpreal 0m0.538suser 0m0.463ssys 0m0.072sreal 0m0.454suser 0m0.386ssys 0m0.065sreal 0m0.387suser 0m0.331ssys 0m0.055s
PHP7 version:
      

      
time /usr/local/php7/bin/php ./public/index.phpreal 0m0.150suser 0m0.123ssys 0m0.024sreal 0m0.137suser 0m0.105ssys 0m0.031sreal 0m0.123suser 0m0.096ssys 0m0.026s
Using the PHP7 version in the thinkphp framework, the performance improvement is about 4 times that of the PHP5 version!
      

      

       
laravel
      
Then we test the framework of the most popular PHP artist.
      

      

       
(1) Framework entrance test
PHP5 version:

      
      
time /usr/bin/php ./public/index.phpreal 0m0.104suser 0m0.081ssys 0m0.022sreal 0m0.148suser 0m0.122ssys 0m0.025sreal 0m0.122suser 0m0.100ssys 0m0.021s
PHP version
      

      
time /usr/local/php7/bin/php ./public/index.phpreal 0m0.079suser 0m0.064ssys 0m0.015sreal 0m0.081suser 0m0.067ssys 0m0.014sreal 0m0.067suser 0m0.054ssys 0m0.013s
We can see In the laravel framework entry test, there is not much difference in performance between PHP5 and PHP7, but even the fastest version of PHP5, 0.081s, is slower than the slowest version of PHP7, 0.067s. So PHP7 is still better.
      

      

       
(2) Framework logic test
Try to add a little logic, like thinkphp, to reuse the test logic.
First modify the laravel routing and directly call the index method of UserController:

      
      
Route::get('/', 'UserController@index');
Write the test logic in the index method:
      

      
public function index(){$arr = array();for ($i = 0; $i < 500000; $i++) {$arr[$i] = $i;}$tmp = array();foreach ($arr as $i) {if ($i % 2 == 0) {$is_exists = array_key_exists($i, $arr);if ($is_exists) {array_push($tmp, $i);}}}}
PHP5 version
      

      
time /usr/bin/php ./public/index.phpreal 0m0.510suser 0m0.377ssys 0m0.079sreal 0m0.627suser 0m0.447ssys 0m0.091sreal 0m0.519suser 0m0.436ssys 0m0.079s
PHP7 version
      

      
time /usr/local/php7/bin/php ./public/index.phpreal 0m0.201suser 0m0.167ssys 0m0.032sreal 0m0.216suser 0m0.174ssys 0m0.040sreal 0m0.169suser 0m0.134ssys 0m0.034s
PHP7 performance has been improved by 3 to 4 times
      

      
Stress test
      
1000 requests, 50 concurrency
      

       
PHP5 version:

      
      
Three samples are as follows:
      

      

      

      

      

       ##PHP7 version:
       

       

      
      

      

      

      
Through the stress test, under the PHP7 version, you can see that the average of the single request time and request completion time, as well as the actual running time of each connection request, are less time-consuming. The most important thing is The performance index QPS is also higher than the PHP5 version.
      
Opcache performance test of PHP7
      
Enable opcache:
      


      

      

      

      
Damn it! PHP7 with opcache turned on is indeed about to take off. Compared with PHP7 that has not been turned on, the performance has improved by more than ten times, and compared with PHP5, it has improved by nearly 20 times! Asking if you are afraid!
      
PHP script test data is as follows:
      

      

      
PHP7 vs PHP5
      
Pure PHP script test process, PHP7 performance About 3 to 4 times that of PHP5.
      
The stress test data is as follows:
      

      
PHP5 vs PHP7 vs PHP7 OPCACHE
      
Conclusion:
      
This article makes a simple comparison between PHP7 and PHP5. The performance is indeed improved by 3 to 4 times. Whether in PHP pure scripts or in frameworks, PHP7's high-performance performance is consistent.
      
PHP7 is fast, PHP7 OpCache is fast, PHP7 is really awesome, a new era of PHP has arrived, use it quickly!
