php mysql basic step by step tutorial - part 10: In looking for one or more data in the database, you can use syntax such as:
SELECT field1,field2,... FROM name_table WHERE condition1,condition2,...
ORDER BY name_field

If field displayed is all field from the table, so all of the name field itself does not have to be declared but it is enough to change with the sign * then all field will be accessed. ORDER BY parameter shows the data that is organized based on which field you choose. The default sequence is from the smallest one (number sequence), from A-Z (letter sequence), and from the first data to the last data (time sequence). You can reverse these sequence by adding DESC attribute. For example, we will search all of the database data of data_employees and show it based on the name field.


<html>
<head>
<title>Search data</title>
</head>
<body>
<table>
  <tr>
    <td align="center">EMPLOYEES DATA</td>
  </tr>
  <tr>
    <td>
      <table border="1">
      <tr>
        <td>NAME</td>
        <td>EMPLOYEES<br>NUMBER</td>
        <td>ADDRESS</td>
      </tr>
<?
//the example of searching data 
with the sequence based on the field name
//search.php
mysql_connect("localhost","root","admin");//database connection
mysql_select_db("employees");
				
$order = "SELECT * FROM data_employees ORDER BY name";
//order to search data
//declare in the order variable
				
$result = mysql_query($order);	
//order executes the result is saved
//in the variable of $result
				
while($data = mysql_fetch_row($result)){
  echo("<tr><td>$data[1]</td><td>$data[0]</td><td>$data[2]</td></tr>");
}
?>
    </table>
  </td>
</tr>
</table>
</body>
</html>

The result:

php mysql display data

Then, you can use DESC like
$order = "SELECT * FROM data_employees ORDER BY name DESC"
so the result will be:

php mysql display data
