+
+# Code
+
+The code will eventually include:
+- db_link.php to connect to a PostgreSQL database and store a record
+- manifest.json and other non-standard standard Chrome Extension baseline files
+- html code for the web page
+

db_link.php

+<?php
+// Connecting, selecting database
+$user = ""; 
+$pass = ""; 
+$db = "test"; 
+
+$con = pg_connect("dbname=$db user=$user password=$pass")
+    or die ("Could not connect to server\n"); 
+
+// Performing SQL query
+$query = 'SELECT * FROM agency limit 10';
+$result = pg_query($query) or die('Query failed: ' . pg_last_error());
+
+// Printing results in HTML
+//echo "<table>\n";
+//while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {
+//    echo "\t<tr>\n";
+//    foreach ($line as $col_value) {
+//        echo "\t\t<td>$col_value</td>\n";
+//    }
+//    echo "\t</tr>\n";
+//}
+//echo "</table>\n";
+
+echo "done\n";
+
+// Free resultset
+pg_free_result($result);
+
+// Closing connection
+pg_close($con);
