Question

我尝试了不止一次，但每次都会出现同样的错误。

mysql --user="root" --password="rootpass" -e "GRANT ALL PRIVILEGES ON *.* TO 'snap' with grant option;"

功能

Fatal error: Out of memory (allocated 507510784) (tried to allocate 16384 bytes) in ..(location)..\accounts.php on line 51

这就是我所说的。

public function getUser($userBase, $allowID = true, $allowUName = true, $allowEmail = true, $allowHash = true) {
            // If nothing allowed!
            if ($allowID == false && $allowUName == false && $allowEmail == false && $allowHash == false) {
                return NULL;
            }
            if ( $allowID == true ) {
                // User ID
                $result = $this->conn->query( "SELECT * FROM `accounts` WHERE `id` = {$userBase}" );
                if ( $result && $result->num_rows > 0 ) {
                    return new user( $this->conn, $userBase );
                }
            }
            if ( $allowUName == true ) {
                // User Name
                $result = $this->conn->query( "SELECT * FROM `accounts` WHERE `username` = '{$userBase}'" );
                if ( $result && $result->num_rows > 0 ) {
                    return new user( $this->conn, $userBase );
                }
            }
            if ( $allowEmail == true ) {
                // Email
                $result = $this->conn->query( "SELECT * FROM `accounts` WHERE `email` = '{$userBase}'" );
                if ( $result && $result->num_rows > 0 ) {
                    return new user( $this->conn, $userBase );
                }
            }
            if ( $allowHash == true ) {
                $result = $this->conn->query( "SELECT * FROM `accounts` WHERE `hash` = '{$userBase}'" );
                if ( $result && $result->num_rows > 0 ) {
                    return new user( $this->conn, $userBase );
                }
            }
            return NULL;
        }

我不知道它使用这个巨大内存的原因。

到目前为止，我理解了这个问题

包含连接到数据库并再次加载它的新用户的行，导致无限循环尝试达到结果然后失败！

这段代码中是否有任何错误导致内存泄漏？
