<html>
<p>In most of project mostly clients wants to export their database in to CSV / Eecel file. It will help us to make a simple record or in future we can also import the same data in to MySql database.</p>
<p>In this tutorial, I will explain you <strong>How To Export MySql To CSV </strong>very easily. </p>
<h2><strong>Export MySql To CSV</strong></h2>
<p><img src="https://steemitimages.com/DQmXaohkF1pw1rMMsYJ3mrzcLyP15nDtbXNKeEZbKz5jNQk/image.png" width="600" height="300"/></p>
<p> </p>
<h2>STEP 1:Assigning the Mysql database & table.</h2>
<ul>
<li>$host: Hostname or an ip adress. it is usualy <strong>localhost</strong>.</li>
<li>$db: Mysql user account used to access the database.</li>
<li>$user: this is the password for the Mysql user account.It is usualy <strong>root</strong>.</li>
<li>$pass: this is the name of the Mysql database used.It is usualy blank.</li>
<li>$table: The name of the table that you want from Mysql to csv.</li>
</ul>
<h2>STEP 2: Creating the connection to the Mysql database-export.php</h2>
<p>In this function, I will create a simple MySql database connection using the above assigning variable.Now as you can see we are calling here exportMysqlToCsv($table) function and passing the name of table. In Next step we will create this function.</p>
```
<?php
$host = 'localhost'; // MYSQL database host adress
$db = ''; // MYSQL database name
$user = ''; // Mysql Datbase user
$pass = ''; // Mysql Datbase password
// Connect to the database
$link = mysql_connect($host, $user, $pass);
mysql_select_db($db);
require 'exportMysqlToCsv.inc.php';
$table=""; // this is the tablename that you want to export to csv from mysql.
exportMysqlToCsv($table);
?>
```
<h2>STEP 3: Creating 'exportMysqlToCsv' function-exportMysqlToCsv.inc.php</h2>
<p>Create a php file and named it as 'exportMysqlToCsv.inc.php'.</p>
```
<?php
function exportMysqlToCsv($table,$filename = 'export.csv')
{
$csv_terminated = "\n";
$csv_separator = ",";
$csv_enclosed = '"';
$csv_escaped = "\\";
$sql_query = "select * from $table";
// Gets the data from the database
$result = mysql_query($sql_query);
$fields_cnt = mysql_num_fields($result);
$schema_insert = '';
for ($i = 0; $i < $fields_cnt; $i++)
{
$l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed,
stripslashes(mysql_field_name($result, $i))) . $csv_enclosed;
$schema_insert .= $l;
$schema_insert .= $csv_separator;
} // end for
$out = trim(substr($schema_insert, 0, -1));
$out .= $csv_terminated;
// Format the data
while ($row = mysql_fetch_array($result))
{
$schema_insert = '';
for ($j = 0; $j < $fields_cnt; $j++)
{
if ($row[$j] == '0' || $row[$j] != '')
{
if ($csv_enclosed == '')
{
$schema_insert .= $row[$j];
} else
{
$schema_insert .= $csv_enclosed .
str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $row[$j]) . $csv_enclosed;
}
} else
{
$schema_insert .= '';
}
if ($j < $fields_cnt - 1)
{
$schema_insert .= $csv_separator;
}
} // end for
$out .= $schema_insert;
$out .= $csv_terminated;
} // end while
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Length: " . strlen($out));
// Output to browser with appropriate mime type, you choose <img src="icon_wink.gif" alt=";)" class="wp-smiley">
header("Content-type: text/x-csv");
//header("Content-type: text/csv");
//header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=$filename");
echo $out;
exit;
}
?>
```
<p>As you can see the code in this function we are passing the table name using $table variable. In this example default filename of the exported file is <em>export.csv.</em> you can change it as you like to append date.(ex.export-15-02-20182.csv) </p>
