The operating environment of this article: Ubuntu1804 system, php7.2 version, DELL G3 computer

PHP uses uuid

Environment

Ubuntu1804 php7.2 nginx

Preparation

Go to the PECL official website (https://pecl.php.net/package/uuid) to download the latest php uuid extension:

For example, uuid-1.1.0 version

$ wget https://pecl.php.net/get/uuid-1.1.0.tgz

Install the dependent library

The most important component of uuid is the machine code, most of which are the network card MAC address. PHP cannot obtain the machine code, so the code cannot be used directly to generate a uuid

Under ubuntu this package is uuid-dev, other platforms are similar

$ sudo apt-get install uuid-dev

Source code compilation and installation

• Unzip the package

$  tar -zxvf uuid-1.1.0.tgz

• Enter the root directory of the package

$ cd uuid-1.1.0/

• Initialization

$ phpize7.2

phpize command is used to prepare PHP The compilation environment of the extension library.
Generally in the bin directory, multiple versions of PHP find their corresponding phpize, such as /bin/phpize7.2

• Configuration

$ ./configure --with-php-config=/usr/bin/php-config7.2

php-config is a simple command line script used to obtain information about the installed PHP configuration

• Installation

$ sudo make
$ sudo make test
$ sudo make install

The file generated after successful installation is usually modules/××.so

Libraries have been installed in:
   /home/vagrant/uuid-1.1.0/modules

or

  Installing shared extensions:     /usr/lib/php/20170718/

in the current directory. If the extension .so file is not automatically added to the extension directory (you can view the extension_dir directory through phpinfo, which is the "/usr/lib/php/20170718/" above), you need to manually copy

$ sudo cp /home/vagrant/uuid-1.1.0/modules/uuid.so /usr/lib/php/20170718/

Configuration extension

We just installed the extensions before, but the specific extensions introduced in cli and fpm modes generally need to be configured separately

• Add the uuid extension to the corresponding configuration file

1. The old way of adding is usually to add a line directly to the php.ini file: extension=uuid.so;

2. The new version is easier to manage and is usually /etc/php/php7.2/mods- availableAdd the uuid.ini file and add a line extension=uuid.so;

3. Add it to the fpm and cli configuration

$ sudo ln -s /etc/php/7.2/mods-available/uuid.ini /etc/php/7.2/fpm/conf.d/uuid.ini
 
$ sudo ln -s /etc/php/7.2/mods-available/uuid.ini /etc/php/7.2/cli/conf.d/uuid.ini

4. Restart fpm

sudo service php7.2-fpm reload

5. Check whether the installation is successful

• In cli mode

$ php -m |grep uuid

• In fpm mode

Through phpinfo () View

Use

<?php

if (function_exists(&#39;uuid_create&#39;) === true) {
    echo uuid_create(), "<br>";
    echo uuid_create(1);
} else {
    echo &#39;uuid未安装&#39;;
}

output example:
