This guide will walk you through the process of creating and populating a new SQLite database using XAMPP, then accessing the data within it using PHP.</p> </div> <div class="paragraph"> <p>Begin by creating and populating a new database using the SQLite command-line client, as below:</p> </div> <div class="olist arabic"> <ol class="arabic"> <li> <p>Open your Windows command prompt by clicking the “Shell” button in the XAMPP control panel.</p> </li> <li> <p>Change to the <em>htdocs\</em> subdirectory of your XAMPP installation directory (typically <em>C:\xampp</em>) and create a new SQLite database file named <em>mydb.sq3</em> with the SQLite command-line client:</p> <div class="literalblock"> <div class="content"> <pre>cd C:\xampp\htdocs sqlite3 mydb.sq3</pre> </div> </div> <div class="paragraph"> <p>You should now see an SQLite prompt, as below:</p> </div> <div class="imageblock"> <div class="content"> <img src="./images/use-sqlite/image1.png" alt="image1"> </div> </div> </li> <li> <p>At the <em>sqlite></em> prompt, create a new table to hold your data. In this example, the table is named items and it contains 3 columns, for item ID, item name and item cost. You can use standard CREATE TABLE syntax to create the table, and you can <a href="http://www.sqlite.org/datatype3.html">learn more about SQLite’s built-in datatypes here</a>.</p> <div class="literalblock"> <div class="content"> <pre>CREATE TABLE items (id INTEGER PRIMARY KEY, name TEXT, price REAL);</pre> </div> </div> </li> <li> <p>Add some data to the new inventory table using INSERT commands, as shown below:</p> <div class="literalblock"> <div class="content"> <pre>INSERT INTO items VALUES ('1001', 'Salt', 3.15); INSERT INTO items VALUES ('1002', 'Pepper', 2.75); INSERT INTO items VALUES ('1003', 'Eggs', 2.00); INSERT INTO items VALUES ('1004', 'Bacon', 7.25); INSERT INTO items VALUES ('1005', 'Milk', 1.15); INSERT INTO items VALUES ('1006', 'Strawberries', 8.73); INSERT INTO items VALUES ('1007', 'Cereal', 2.65);</pre> </div> </div> </li> <li> <p>You can now also run a SELECT query on the data. For example, the query below returns all items that cost less than $3:</p> <div class="literalblock"> <div class="content"> <pre>SELECT * FROM items WHERE price < 3.00;</pre> </div> </div> <div class="imageblock"> <div class="content"> <img src="./images/use-sqlite/image2.png" alt="image2"> </div> </div> </li> <li> <p>Once you’re done using the database, exit it by typing <em>.quit</em> at the <em>sqlite></em> prompt.</p> </li> </ol> </div> <div class="admonitionblock important"> <table> <tr> <td class="icon"> <i class="fa icon-important" title="Important"></i> </td> <td class="content"> The database file (in this example, <em>mydb.sq3</em>) contains all your tables and data, so you should remember to back it up regularly. </td> </tr> </table> </div> <div class="paragraph"> <p>The previous steps discussed how to create and use an SQLite database using the command-line client. However, more often than not, you’ll be using an SQLite database in combination with a PHP-powered Web application. XAMPP includes the PHP SQLite extension, so doing this is not very difficult at all.</p> </div> <div class="paragraph"> <p>To connect to your SQLite database and execute queries on it with PHP, use your text editor to create an example script named <em>sqlite.php</em> in the <em>htdocs</em> subdirectory of your XAMPP installation directory and fill it with the following code:</p> </div> <div class="literalblock"> <div class="content"> <pre><?php $db = new SQLite3('mydb.sq3'); $sql = "SELECT * FROM items WHERE price < 3.00"; $result = $db->query($sql); while ($row = $result->fetchArray(SQLITE3_ASSOC)){ echo $row['name'] . ': $' . $row['price'] . '<br/>'; } unset($db);</pre> </div> </div> <div class="paragraph"> <p>The first line of code creates a new SQLite3 object, using the <em>mydb.sq3</em> database file you created earlier. Then, the object’s <em>query()</em> method is used to execute a SELECT query on the database, and the result object’s <em>fetchArray()</em> method is used to iterate over the result set. Adding the SQLITE3_ASSOC parameter to the <em>fetchArray()</em> method tells PHP to return the results as an associative array, making it easy to access individual fields of the result set and display them on a Web page.</p> </div> <div class="paragraph"> <p>Once done, save your changes and ensure that your Apache server is running. Then, browse to <a href="http://localhost/sqlite.php" class="bare">http://localhost/sqlite.php</a> to execute the script.
