SQL Limit in PHP
0 likes1,801 views
This document discusses using the LIMIT operator in SQL queries executed from PHP code. The LIMIT operator allows restricting the number of rows returned from a database query. The example shows connecting to a database, running a SELECT query with LIMIT 0,5 to retrieve the first 5 rows, and outputting the results in an HTML table. Using LIMIT in PHP queries provides a way to page through large result sets by controlling the number of rows fetched.
![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

<?php
$con = mysql_connect("localhost","root","");
if (!$con) {

}
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'>

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);
