Hi,


I just installed PHP on Ubuntu 16.04 LTS and by default it install version 7. So I was trying to install your project, but after entering the login information it would load blank page and not connect. I checked the apache2 error logs, and it displayed the error message "Call to undefined function mysql_connect()" in "includes/class/Sql.php".

I replaced all mysql_* function with mysqli_*. While replacing I noticed somebody has mentioned that behaviour of mysql_result is slightly different than mysqli_result, "http://php.net/manual/en/class.mysqli-result.php#109782". I replaced.

After replacement, I was able to login, but it would not display any database, tables, users, or any server information.

Following more errors were occurred.

"PHP Warning:  mysqli_error() expects exactly 1 parameter" in "includes/class/Sql.php" on "line 152".

Regards

 Your best bet is to make some changes to Sql.php class to convert mysql to PDO. There's already PDO support. You'll need to change connect to us PDO, and then the method to pdo. You'll also need to fix getMetadata() which uses some mysql specific stuff. I took out the first section and used the second:

if ($this->conn) {

                        if ($this->adapter == "mysql") {

                                $schemaSql = $this->listDatabases();

                                if ($this->rowCount($schemaSql)) {

                                        while ($schema = $this->fetchArray($schemaSql)) {

                                                $output .= '{"name": "' . $schema[0] . '"';


                                                $this->selectDB($schema[0]);

                                                $tableSql = $this->listTables();


                                                if ($this->rowCount($tableSql)) {

                                                        $output .= ',"items": [';

                                                        while ($table = $this->fetchArray($tableSql)) {

                                                                $countSql = $this->query("SELECT COUNT(*) AS `RowCount` FROM `" . $table[0] . "`");

                                                                $rowCount = (int)($this->result($countSql, 0, "RowCount"));

                                                                $output .= '{"name":"' . $table[0] . '","rowcount":' . $rowCount . '},';

                                                        }


                                                        if (substr($output, -1) == ",")

                                                                $output = substr($output, 0, -1);


                                                        $output .= ']';

                                                }

                                                $output .= '},';

                                        }

                                        $output = substr($output, 0, -1);

                                }

                        } else if ($this->adapter == "sqlite") {



There's also a bug in rowCount for the pdo method:

        function rowCount($resultSet) {

                if (!$resultSet)

                        return false;

                if ($this->conn) {

                        if ($this->method == "pdo") {

                                return $resultSet->rowCount();

                                //return count($resultSet->fetchAll());

                        } else if ($this->method == "mysql") {

                                return @mysql_num_rows($resultSet);

                        } else if ($this->method == "sqlite") {

                                return @sqlite_num_rows($resultSet);

                        }

                }

        }

PDO is a good option, as suggested by phpGuru.
I've did a little and quick fix yesterday, using mysqli (Function orientated, not the best, i know, but working)

You can download and check it at:

This SqlBuddy Version handles MySqli and works at least up to PHP v.7.0.25 on my Servers.
