| 1     | Girish  |  20000 |
| 10    | Komal   |  20000 |
| 2     | Amit    |  21000 |
| 3     | CH      |  22000 |
| 4     | V       |  23000 |

| 8     | W       |  27000 |
| 9     | AS      |  28000 |
+-------+---------+--------+
10 rows in set (0.00 sec)

Searching data from the table data using Mysql php where:

The code connect the front end in PHP to the backend Mysql database. The front end fetches the records from Mysql database and print the records in browser on the basis of condition specified in WHERE Clause.

<?php
$database="girish";
$user="root";
$password="root";
$host="192.168.10.126";
$link= mysql_connect($host,$user,$password) or die("Could not connect: ".mysql_error());
mysql_select_db($database,$link) or die("Error in selecting the database:".mysql_error());
$sql="select * from mytable where Empname like \"%h\"";
mysql_query($sql,$link) or exit("Sql Error".mysql_error());
$sql_result=mysql_query($sql,$link) or exit("Sql Error".mysql_error());

$sql_num=mysql_num_rows($sql_result);
echo "<table border=\"1\" bgcolor=\"#CCCCFF\" >";
echo "<tr><td><b>Empid</b></td><td><b>Empname</b></td><td><b>Salary</b></td>" ;
while($sql_row=mysql_fetch_array($sql_result))
{
$Empid=$sql_row["Empid"];
$Empname=$sql_row["Empname"];
$Salary=$sql_row["Salary"];
echo "<tr>";
echo "<td>".$Empid."</td>";
echo "<td>".$Empname."</td>";
echo "<td>".$Salary."</td>";
echo "</tr>";
} 
echo "</table>";
?>
