Operating MongoDB database with PHP_PHP tutorial-PHP Tutorial-php.cn

<p></p> <h2>PHP operates MongoDB database</h2> <p> </p> <p> </p> <p><strong>1. Introduction to MongoDB</strong></p> <p>MongoDB (the name comes from "humongous") is a scalable, high-performance, open source, schema-free, document-oriented database that combines the advantages of document databases, key-value storage and relational databases. </p> <p><b> </b></p> <p><strong>MongoDB features: </strong></p> <p>• Document-oriented storage (JSON-like data schema is simple and powerful)<br> • Dynamic query<br> • Full index support, extended to internal objects and embedded arrays <br> • Query record analysis<br> • Fast, in-place updates <br> • Efficiently store binary large objects (such as photos and videos) <br> • Replication and failover support<br> • Auto-Sharding supports cloud-level scalability<br> • MapReduce supports complex aggregations <br> • Business support, training and consulting</p> <p> </p> <p><strong>2. Install MongoDB</strong></p> <p>Installing MongoDB is very simple, just download the compressed package, decompress it and run the command </p> <p><strong>Download address: </strong> https://www.mongodb.org/downloads</p> <p>This article is for Windows platform, MongoDB running command: >bin/mongod</p> <p>Tip: First create a folder to store data. MongoDB’s default data storage directory is /data/db/ (or c:datadb). Of course, you can also change it to a different directory by specifying the –dbpath parameter. </p> <p><strong> Example: </strong><br> >bin/mongod –dbpath=d:mgdatadb</p> <p>For more information, please refer to my CSDN blog: MongoDB installation configuration</p> <p> </p> <p><strong>3. Install MongoDB PHP extension </strong></p> <p>Download the PHP extension according to your PHP version: </p> <p>http://php.net/manual/en/mongo.installation.php#mongo.installation.nix<br> http://www.php.net/manual/en/mongo.installation.php#mongo.installation.windows</p> <p>Tips: <br> 1. VC6 is suitable for Apache and VC9 is suitable for IIS; <br> 2. Thread safe is suitable for PHP running in module mode, and Non-thread safe is suitable for CGI running mode. <br> Modify php.ini, add: extension=php_mongo.dll, and restart the web server. </p> <p>Ubuntu installation steps: </p> <p>1. Download the plug-in: mongo-php-driver</p> <p>2. Unzip and install: </p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="code"> $ tar zxvf mongodb-mongodb-php-driver-<commit_id>.tar.gz $ cd mongodb-mongodb-php-driver-<commit_id> $ phpize $ ./configure $ make all $ sudo make install</commit_id></commit_id></pre><div class="contentsignin">Copy after login</div></div> <p>3. Configure php.ini</p> <p>#extension=uploadprogress.so<br> #extension=http.so<br> #extension=intl.so<br> #extension=curl.so</p> <p>extension=/usr/lib/php5/20121212/curl.so<br> extension=/usr/lib/php5/20121212/gd.so<br> extension=/usr/lib/php5/20121212/json.so<br> extension=/usr/lib/php5/20121212/mysql.so<br> extension=/usr/lib/php5/20121212/mysqli.so<br> #extension=/usr/lib/php5/20121212/opcache.so<br> extension=/usr/lib/php5/20121212/pdo.so<br> extension=/usr/lib/php5/20121212/pdo_mysql.so<br> #extension=/usr/lib/php5/20121212/readline.so<br> #extension=/usr/lib/php5/20121212/xdebug.so<br> extension=/usr/local/lib/php/extensions/no-debug-non-zts-20121212/redis.so<br> extension=/usr/local/lib/php/extensions/no-debug-non-zts-20121212/mongo.so</p> <p>4. Restart apache</p> <p>sudo /etc/init.d/apache2 restart</p> <p>5. Modify the default startup items (optional) </p> <p>sudo vim /etc/apache2/apache2.conf</p> <p>Add the configuration code as follows: </p> <table border="0" cellpadding="0" cellspacing="0"> <tbody> <tr> <td class="gutter">1234567891011121314</td> <td class="code"><code class="python" plain=""><virtualhost code=""><code class="python" keyword="">*</code><code class="python" plain="">:</code><code class="python" value="">80</code><code class="python" plain="">></code><code class="python" spaces=""> </code><code class="python" plain="">ServerAdmin webmaster@localhost</code><code class="python" spaces=""> </code><code class="python" plain="">DocumentRoot </code><code class="python" keyword="">/</code><code class="python" plain="">home</code><code class="python" keyword="">/</code><code class="python" plain="">homer</code><code class="python" keyword="">/</code><code class="python" plain="">workspace</code><code class="python" spaces=""> </code><code class="python" plain=""><directory code=""><code class="python" keyword="">/</code><code class="python" plain="">home</code><code class="python" keyword="">/</code><code class="python" plain="">homer</code><code class="python" keyword="">/</code><code class="python" plain="">workspace</code><code class="python" keyword="">/</code><code class="python" plain="">money_client></code><code class="python" spaces=""> </code><code class="python" plain="">DirectoryIndex index.html index.php</code><code class="python" spaces=""> </code><code class="python" plain="">Options Indexes FollowSymLinks</code><code class="python" spaces=""> </code><code class="python" plain="">AllowOverride </code><code class="python" color1="">None</code><code class="python" spaces=""> </code><code class="python" plain="">Require </code><code class="python" functions="">all</code> <code class="python" plain="">granted</code><code class="python" spaces=""> </code><code class="python" plain=""><</code><code class="python" keyword="">/</code><code class="python" plain="">Directory></code><code class="python" spaces=""> </code><code class="python" plain="">ServerName localhost</code><code class="python" spaces=""> </code><code class="python" plain="">DirectoryIndex index.html index.php</code><code class="python" spaces=""> </code><code class="python" plain="">ErrorLog ${APACHE_LOG_DIR}</code><code class="python" keyword="">/</code><code class="python" plain="">error_alibuyer.log</code><code class="python" spaces=""> </code><code class="python" plain="">CustomLog ${APACHE_LOG_DIR}</code><code class="python" keyword="">/</code><code class="python" plain="">access_alibuyer.log combined</code><code class="python" plain=""><</code><code class="python" keyword="">/</code><code class="python" plain="">VirtualHost></code></directory></code></virtualhost></code></td> </tr> </tbody> </table> <p> </p> <p><strong>4.
