    <p>i am trying to combine AngularJS with a php backend. Right now i am trying to generate a json with php to return it to a http request to angular. So far i created this php.</p> <pre><code>$dbhost = "localhost"; $dbport = "5432"; $dbname = "fixevents"; $dbuser = "postgres"; $dbpass = "123"; $connect = pg_connect("host=" . $dbhost . " port=" . $dbport . " dbname=" . $dbname . " user=" . $dbuser . " password=" . $dbpass); $query = "SELECT contact_firstname, contact_lastname, contact_id, contact_email FROM contact WHERE user_id = 1"; $result = pg_query($connect, $query); $comma = ''; $json = '['; while ($row = pg_fetch_array($result)) { $json .= $comma . '{'; $json .= 'contact_firstname:"' . addslashes($row['contact_firstname']) . '",'; $json .= 'contact_lastname:"' . addslashes($row['contact_lastname']) . '",'; $json .= 'contact_id:' . addslashes($row['contact_id']) . ','; $json .= 'contact_email:['; $contact_email = explode(',,,', addslashes($row['contact_email'])); $comma_email = ''; foreach($contact_email as $email) { $json .= $comma_email . '"' . $email . '"'; $comma_email = ','; } $json .= ']'; $json .= '}'; $comma = ','; } $json .= ']'; echo $json; </code></pre> <p>But i read some comments by greater minds than mine :) and they said creating the json manually is not the best idea. Can anyone tlel me how to generate this json is a more stylish way? I saw something about json_endode and array but i dont know how to add a list inside a list. I have a list and inside each list item i have another list with emails because 1 contact can have more emails. My generated JSON right now looks like this </p> <pre><code>[{contact_firstname:"Daniel",contact_lastname:"Pacuraru",contact_id:1,contact_email:["pacurarudaniel@gmail.com","hello@pacurarudaniel.com"]},{contact_firstname:"Someone",contact_lastname:"Else",contact_id:2,contact_email:["someone.else@gmail.com"]}] </code></pre> <p>Thank you, Daniel!</p> <p>EDIT</p> <pre><code>$myjson = array(); while($row = pg_fetch_array($result)) { $json = array( 'contact_firstname' =&gt; addslashes($row['contact_firstname']), 'contact_lastname' =&gt; addslashes($row['contact_lastname']), 'contact_id' =&gt; addslashes($row['contact_id']), 'contact_email' =&gt; explode(',,,', addslashes($row['contact_email'])) ); array_push($myjson, $json); } echo json_encode($myjson); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
