PHP SQL IF Statement

 This example illustrates how to use the 'if' statement when accessing the data from mysql database table in php. 

In this example we create a connection from database table using mysql_connect("hostName", "userName", "Password"). After the connection created we choose database by mysql_select_db("databaseName", connectionObject) and finally we execute query by mysql_query("SELECT * FROM tableName"). The founded result display in the table as row and column wise. Here we are using the if statement, so only one data will display here as shown in the output.

 

Source Code of IF_Statement.php

<?php
  $con = mysql_connect("localhost","root","root");
  if (!$con) {
    die('Could not connect: ' . mysql_error());
  }

  mysql_select_db("test", $con);
  $result = mysql_query("SELECT * FROM emp");
  echo "<table border='1'>
    <tr>
      <th>id</th>
      <th>Name</th>
    </tr>";
    if($row = mysql_fetch_array($result)) {
      echo "<tr>";
      echo "<td>" . $row['id'] "</td>";
      echo "<td>" . $row['name'] "</td>";
      echo "</tr>";
    }
  echo "</table>";
  
  mysql_close($con);
?>
