基於php7的專案要安裝mongodb類庫
阿新 • • 發佈：2018-12-24
公司的一個專案要從php5.6升級到php7版本，專案的mongo類庫用不了，看了php手冊，發現要對於php7要安裝新的類庫。php7需要使用的library是 mongodb而不是舊的mongo，所以要在專案中下載這個mongodb（library）。
對於一個要安裝mongodb library的專案，直接用composer下載，使用composer require mongodb/mongodb，但是報錯
localhost:libraries taiwu$ composer require mongodb/mongodb Using version ^1.3 for mongodb/mongodb ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - mongodb/mongodb 1.3.1 requires ext-mongodb ^1.4.0 -> the requested PHP extension mongodb is missing from your system. - mongodb/mongodb 1.3.0 requires ext-mongodb ^1.4.0 -> the requested PHP extension mongodb is missing from your system. - Installation request for mongodb/mongodb ^1.3 -> satisfiable by mongodb/mongodb[1.3.0, 1.3.1]. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/5.6/php.ini - /usr/local/etc/php/5.6/conf.d/ext-mcrypt.ini You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode. Installation failed, reverting ./composer.json to its original content.
上面錯誤說明兩個問題：
a. 我的系統使用php -v，肯定得到的是5.6版本，因為我安裝了php7版本，但是沒有php7放到PATH中更靠前的設定，所以系統直接使用php時，用了5.6。既然主要用php7就，就要設定下PATH。（用命令export PATH=/usr/local/opt/php70/bin/:$PATH）
b.我的php（這裡報錯說的是5.6）並沒有按照mongodb擴充套件，這個通過php -v能看出來的。
那麼我們先讓php7版本成為預設的php指令，修改PATH即可，這樣在執行composer，它使用的php就是php7了。這時報錯資訊，就是php7.0要加上mongodb擴展才行
解決上面的問題，最終讓基於php7的專案能安裝mongodb library很簡單，只要保證系統安裝的php7，且安裝了mongodb擴充套件。localhost:libraries taiwu$ echo $PATH /Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/opt/php56/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin localhost:libraries taiwu$ export PATH=/usr/local/opt/php70/bin/:$PATH localhost:libraries taiwu$ echo $PATH /usr/local/opt/php70/bin/:/Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/opt/php56/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin localhost:libraries taiwu$ composer require mongodb/mongodb Using version ^1.3 for mongodb/mongodb ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.

下面說一下具體步驟：
1、因為是mac pro，通過homebrew安裝軟體非常方便, 用它安裝php7
使用brew search php7,來檢視下載php7的具體引數，如下，homebrew/php/php70就是我要下載的版本
localhost:fanghuwang_global taiwu$ brew search php7
==> Searching local taps...
homebrew/php/php70 ✔ homebrew/php/php70-pspell homebrew/php/php71-imagick homebrew/php/php72-ast
homebrew/php/php70-amqp homebrew/php/php70-pthreads homebrew/php/php71-ioncubeloader homebrew/php/php72-blitz
homebrew/php/php70-apcu homebrew/php/php70-raphf homebrew/php/ 使用brew install homebrew/php/php70，但是報錯了，提示衝突的公式（具體含義參考brew官網），按照下面提示操作，使用brew unlink php53即可。
localhost:~ taiwu$ brew install homebrew/php/php70
==> Installing php70 from homebrew/homebrew-php
Error: Cannot install homebrew/php/php70 because conflicting formulae are installed.
php53: because different php versions install the same binaries.
Please `brew unlink php53` before continuing.
Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.
localhost:~ taiwu$ brew unlink php53
Unlinking /usr/local/Cellar/php53/5.3.29_3... 16 symlinks removed繼續安裝，安裝成功。可以看到php的路徑等資訊如下,
然後執行 export PATH=/usr/local/opt/php70/bin/:$PATH， 這樣shell中使用php命令，就是php7.0的了
localhost:~ taiwu$ brew install homebrew/php/php70
==> Installing php70 from homebrew/homebrew-php
==> Downloading https://homebrew.bintray.com/bottles-php/php70-7.0.0-rc.3.yosemite.bottle.2.tar.gz
######################################################################## 100.0%
==> Pouring php70-7.0.0-rc.3.yosemite.bottle.2.tar.gz
==> Caveats
To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php7_module /usr/local/opt/php70/libexec/apache2/libphp7.so
<FilesMatch .php$>
SetHandler application/x-httpd-php
</FilesMatch>
Finally, check DirectoryIndex includes index.php
DirectoryIndex index.php index.html
The php.ini file can be found in:
/usr/local/etc/php/7.0/php.ini
✩✩✩✩ Extensions ✩✩✩✩
If you are having issues with custom extension compiling, ensure that
you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:
PATH="/usr/local/bin:$PATH"
PHP70 Extensions will always be compiled against this PHP. Please install them
using --without-homebrew-php to enable compiling against system PHP.
✩✩✩✩ PHP CLI ✩✩✩✩
If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc,
~/.zshrc, ~/.profile or your shell's equivalent configuration file:
export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH"
✩✩✩✩ FPM ✩✩✩✩
To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php70/homebrew.mxcl.php70.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist
The control script is located at /usr/local/opt/php70/sbin/php70-fpm
OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:
PATH="/usr/local/sbin:$PATH"
You may also need to edit the plist to use the correct "UserName".
Please note that the plist was called 'homebrew-php.josegonzalez.php70.plist' in old versions
of this formula.
To have launchd start homebrew/php/php70 at login:
ln -sfv /usr/local/opt/php70/*.plist ~/Library/LaunchAgents
Then to load homebrew/php/php70 now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php70.plist
==> Summary
2、然後基於這個php7安裝mongodb擴充套件了，
檢視php手冊，說mac下通過homebrew直接安裝即可，http://php.net/manual/zh/mongodb.installation.homebrew.php
taiwudeMacBook-Pro:~ taiwu$ brew install php70-mongodb
==> Installing php70-mongodb from homebrew/php
==> Downloading https://pecl.php.net/get/mongodb-1.4.0.tgz
但是上面頁面等了半天沒反應，果斷手動安裝，看手冊另一個安裝說明，http://php.net/manual/zh/mongodb.installation.manual.php，具體步驟如下：
$ git clone https://github.com/mongodb/mongo-php-driver.git
$ cd mongo-php-driver
$ git submodule update --init
$ phpize
$ ./configure
$ make all
$ sudo make install要注意的是，因為我是用的新安裝的php7來進行安裝擴充套件，所以使用phpize的時候，指明具體路徑，用命令/usr/local/opt/php70/bin/phpize 。
最後會提示擴充套件mongodb.so安裝成功。
然後需要在php.ini中進行配置，vi /usr/local/etc/php/7.0/php.ini ，然後加上一句話
extension=mongodb.so
這樣通過php -m能檢視到mongodb的，這說明php7安裝mongodb擴充套件完成了！！！
3、在基於php7的專案中如果要使用mongodb，需要安裝mongodb的library，也即是使用者業務層面的程式碼（這裡不是php7的mongodb擴充套件，而且給使用者寫程式碼用的library）
繼續檢視php手冊http://php.net/manual/zh/mongodb.tutorial.library.php，
直接用composer來給一個專案安裝mongodb library即可，
$ composer require mongodb/mongodb
