Every one know to export MySQL table data as excel sheet from the back end in server.

But we are going to learn Export excel from mysql table data using php code.

Step 1:
create index.php file
simple form action

<style>
.btn {
  background: #3498db;
  background-image: -webkit-linear-gradient(top, #3498db, #2980b9);
  background-image: -moz-linear-gradient(top, #3498db, #2980b9);
  background-image: -ms-linear-gradient(top, #3498db, #2980b9);
  background-image: -o-linear-gradient(top, #3498db, #2980b9);
  background-image: linear-gradient(to bottom, #3498db, #2980b9);
  -webkit-border-radius: 28;
  -moz-border-radius: 28;
  border-radius: 28px;
  font-family: Arial;
  color: #ffffff;
  font-size: 20px;
  padding: 10px 20px 10px 20px;
  text-decoration: none;

<form action="export.php" method="post" name="export_excel">
<button type="submit" id="export" name="export" class="btn btn-primary button-loading" data-loading-text="Loading...">Export CSV/Excel File</button>
			
</form>

step 2: Create export.php file for action. All the code and actions comes under this file

<?php
include 'config.php';    // database configuration
$SQL = "SELECT  * from data";   // select table

$header = '';
$result ='';
$exportTable = mysql_query ($SQL ) or die ( "Sql error : " . mysql_error( ) );  // export query
 
$rows = mysql_num_fields ( $exportTable );    // select all fields from the table
 
for ( $i = 0; $i < $rows; $i++ )       // check all the fields using for loop 
{
    $header .= mysql_field_name( $exportTable , $i ) . "\t";
}
 
while( $row = mysql_fetch_row( $exportTable ) )     // fetching all rows from the tables
{
    $line = '';
    foreach( $row as $value )
    {                                            
        if ( ( !isset( $value ) ) || ( $value == "" ) )
        {
            $value = "\t";
        }
        else
        {
            $value = str_replace( '"' , '""' , $value );
            $value = '"' . $value . '"' . "\t";
        }
        $line .= $value;
    }
    $result .= trim( $line ) . "\n";
}
$result = str_replace( "\r" , "" , $result );
 
if ( $result == "" )
{
    $result = "\nNo Record(s) Found!\n";                        
}
 
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=export.xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$result";
 
?>

Step 3: create config.php for database configuration

<?php
$con = mysql_connect('localhost','root','');
mysql_select_db('your_database_name',$con)
?>
