SQL Limit in PHP

Introduction

PHP has an operator named LIMIT. Using the LIMIT operator you can fetch a minimum and
maximum row from a database. In this article you will see, how to execute the LIMIT
operator of MySQL in PHP.

Suppose that there are ten rows in a table of any database in MySQL. You want to fetch
only five rows from your database; then you will use the LIMIT operator.

Suppose there is the above table in your database. You want to fetch only five rows from
this table. For this purpose you will use the LIMIT operator. An example of the LIMIT
operator is as follows:

Example 1. If you want to see only five rows from a table in MySQL then you will use the
following query:

select * from emp limit 5

Example 2. If you want to see only five rows from a table in PHP form, then you will use
following code.

In this example, we have created a limit.php page, in which we execute a query with the
LIMIT operator. In the LIMIT operator we put minimum and maximum limit of the table
data. For example, the LIMIT 0,5 retrieves the row starting from row number 0 (the first
one) to a maximum of 5 rows.

Code

<html>
<title>Limit in PHP</title>
<body bgcolor="pink">
< h3><u>SQL Limit in PHP<u></h3>
<center>
<?php
$con = mysql_connect("localhost","root","");
if (!$con) {
die( 'Could not connect: ' . mysql_error());
}
mysql_select_db ("sunderdeep", $con); // sunderdeep is a database name
$result = mysql_query ("select * from emp limit 0,5"); // emp is the table name in
database
echo " <table border='2' bgcolor ='skyblue'>
<tr>
<th align='center'>emp_id</th>
<th align='center'>emp_Name</th>
</tr>";
while ($row = mysql_fetch_array ($result)) {
echo "<tr>";
echo "<td align='center'>" . $row ['emp_id'] . "</td>";
echo "<td align='center'>" . $row ['emp_name'] . "</td>";
echo "</tr>";
}
echo "</table>";

mysql_close ($con);
?>
</center>
