Database Connectivity in PHP
This article explains how to insert and select data from a database into a HTML table in PHP.
Using an insert statement you can insert data into a database. Using a select statement you
can select the entire data from a database into a HTML table.
First of all we will create a database.
Create The Database
<html>
<body bgcolor="pink">
<center>
<?php
$con = mysql_connect ("localhost","root","");
$db="MCN";
if (!$con)
{
die ('Could not connect: ' . mysql_error());
}
if (mysql_query ("CREATE DATABASE $db",$con))
{
echo "Your Database Created Which Name is : $db";
}
else
{
echo "Error creating database: " . mysql_error();
}
mysql_close ($con);
?>
</center>
}</body>
</html>
Output
In the above code, we created a database named MCN. Now we will create a table in the
MCN database.

</table>
</center>
</body>

data into the database table is as follows:
<?php
$con=mysql_connect ("localhost","root","");
mysql_select_db("mcn",$con);
@$a=$_POST['txt1'];
@$b=$_POST['txt2'];
@$c=$_POST['txt3'];
@$d=$_POST['txt4'];
if(@$_POST['inser'])
{
$s="insert into employee values ('$a','$b','$c','$d')";
echo "Your Data Inserted";
mysql_query ($s);
}
$con=mysql_connect ("localhost","root","");
mysql_select_db ("mcn",$con);
if(@$_POST ['sel'])
