    die("Can't connect to database");

if (!mysql_select_db($database))

    die("Can't select database");

// sending query

$result = mysql_query("SELECT * FROM view_abc");

if (!$result) {

    die("Query to show fields from table failed");

}

$fields_num = mysql_num_fields($result);

echo "<div class='wrapper'>
<font size=3 color=blue><b>Entry";

echo "</font></b><table class='table'><tr>";

// printing table headers

for($i=0; $i<$fields_num; $i++)

{

    $field = mysql_fetch_field($result);

    echo "<td><b>{$field->name}</b></td>";
}

echo "</tr>\n";

// printing table rows

while($row = mysql_fetch_row($result))

    // of $row to $cell variable

   /* foreach($row as $cell)

        echo "<td>$cell</td>";

Answer 1

use the below query

$res =  mysql_query("SELECT * INTO OUTFILE '$name.csv' FROM users ");

here $name is the name of the file you want to create.

otherwise you can use the present date by using date function instead of a static name. The file will be stored in xampp/mysql/data/your database name ( assuming you are using xampp).
