Change Database Collation with PHP

This little sql statement can change the collation in your database including tables, columns and everywhere. This is something phpMyAdmin can not handle completely.

Credits goes to original poster.


$conn1=new MySQLi("localhost","root","","exam_db");
if($conn1->connect_errno){
    echo mysqli_connect_error();
    exit;
}
$res=$conn1->query("show tables") or die($conn1->error);
while($tables=$res->fetch_array()){
    $conn1->query("ALTER TABLE $tables[0] CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci") or die($conn1->error);
}
echo "The collation of your database has been successfully changed!";

$res->free();
$conn1->close();
