How to Insert JSON Data into My. SQL using PHPHi, in this PHP TUTORIAL, we'll see How to insert JSON Data into My. SQL using PHP. Check out its reverse process of Converting Data from My. SQL to JSON Format in PHP here. Converting json to mysql using php includes several steps and you will learn things like how to read json file, convert json to array and insert that json array into mysql database in this tutorial. For those who wonder what is JSON, let me give a brief introduction. What is JSON File Format? JSON file contains information stored in JSON format and has the extension of "*. JSON stands for Java. Script Object Notation and is a light weight data exchange format. Being less cluttered and more readable than XML, it has become an easy alternative format to store and exchange data. All modern browsers supports JSON format. Example of a JSON File. Read Also: Do you want to know how a JSON file looks like? Well here is the sample. As you can see by yourself, the JSON format is very human readable and the above file contains some employee details. I'm going to use this file as an example for this tutorial and show you how to insert this JSON object into My. JDBC Stored Procedure- Learning JDBC in simple and easy steps using this beginner's tutorial containing basic to advanced knowledge of JDBC including Drivers. What is stored procedure in Sql server | what are the advantages of using stored procedures in sql server. There are reasons to use stored procs, but performance is usually not one of them (there are always exceptions). There are typically other, more standard (cross. SQL database in PHP step by step. Step 1: Connect PHP to My. SQL Database. As the first and foremost step we have to connect PHP to the My. SQL database in order to insert JSON data into My. SQL DB. For that we use mysql_connect() function to connect PHP with My. SQL. $con = mysql_connect("username","password","") or die('Could not connect: ' . Here "employee" is the My. ![]() · Continuing with our series on Stored Procedures and Functions, this month we focus on Stored Functions.SQL Database name we want to store the JSON object. Learn more about using mysqli library for php and mysql database connection here. Step 2: Read the JSON file in PHPNext we have to read the JSON file and store its contents to a PHP variable. But how to read json file in php? Well! PHP supports the function file_get_contents() which will read an entire file and returns it as a string. Let’s use it to read our JSON file. Here "empdetails. JSON file name we want to read. Step 3: Convert JSON String into PHP Array. The next step for us is to convert json to array. Which is likely we have to convert the JSON string we got from the above step to PHP associative array. Again we use the PHP json decode function which decodes JSON string into PHP array. The first parameter $jsondata contains the JSON file contents. The second parameter true will convert the string into php associative array. Step 4: Extract the Array Values. Next we have to parse the above JSON array element one by one and store them into PHP variables. Step 5: Insert JSON to My. SQL Database with PHP Code. Using the above steps, we have extracted all the values from the JSON file. Finally let's insert the extracted JSON object values into the My. SQL table. //insert into mysql table.INSERT INTO tbl_emp(empid, empname, gender, age, streetaddress, city, state, postalcode, designation, department). VALUES('$id', '$name', '$gender', '$age', '$streetaddress', '$city', '$state', '$postalcode', '$designation', '$department')". Error : ' . mysql_error()). We are done!!! Now we have successfully imported JSON data into My. SQL database. Here is the complete php code snippet I have used to insert JSON to My. SQL using PHP. Complete PHP Script. Could not connect: ' . INSERT INTO tbl_emp(empid, empname, gender, age, streetaddress, city, state, postalcode, designation, department). VALUES('$id', '$name', '$gender', '$age', '$streetaddress', '$city', '$state', '$postalcode', '$designation', '$department')". Error : ' . mysql_error()). SJ0. 11. MS". "personal": {. Smith Jones".

SQL using PHP. Last Modified: Feb- 2. My. SQL Database Security Best Practices. The My. SQL database has become the world’s most popular open source database because of its consistent level of fast performance, high reliability and ease of use. It is used everywhere and by everyone. Individuals, web developers, and many of the world’s largest and fastest- growing organizations such as industry leaders Yahoo, Alcatel- Lucent, Google, Nokia, You. Tube and others use it for powering their high- volume websites, business- critical systems, and packaged software. As most products do, it comes out of the box. Usually, security is not a major consideration when installing this kind of product. Often, the most important issue is to get it up and running as quickly as possible so that the organization can benefit from it. This document is intended as a quick security manual to help you bring an installed My. SQL database server into conformity with best security practices. This paper contains code examples that can either be executed in the operation system console, sent to the database via the My. SQL console or added to configuration files. Code snippets are denoted by a gray background. Please refer to the surrounding context for more precise instructions. 1. Secure your server. Many known attacks are possible only once physical access to a machine has been acquired. For this reason, it is best to have the application server and the database server on different machines. If this is not possible, you must make sure to execute remote commands via an application server, otherwise, an attacker may be able to harm your database even without permissions. For this reason, any service running on the same machine as the database should be granted the lowest possible permission privileges that will still allow the service to operate smoothly. Do not forget to install the whole security package: Antivirus and Antispam, Firewall, and all of the security packages recommended by your operating system’s vendor. In addition, do not forget to spend 1. Consider performing some operating system hardening procedures, such as the following: Install Antivirus and Antispam software. Configure the operating system’s firewall. Consider the safety of your server’s physical location. Install the services you intend the machine to run. Harden the production server and services. Disable unnecessary services. Follow services vendors’ recommendations regarding patches and updates needed for the safe and secure operation of their services. Disable or restrict remote access. Consider whether My. SQL will be accessed from the network or only from its own server. If remote access is used, ensure that only defined hosts can access the server. This is typically done through TCP wrappers, iptables, or any other firewall software or hardware available on the market. To restrict My. SQL from opening a network socket, the following parameter should be added in the [mysqld] section of my. The file is located in the “C: \Program Files\My. SQL\My. SQL Server 5. Windows operating system or “/etc/my. Linux. This line disables the initiation of networking during My. SQL startup. Please note that a local connection can still be established to the server. Another possible solution is to force My. SQL to listen only to the local host by adding the following line in the [mysqld] section of my. You may not be willing to disable network access to your database server if users in your organization connect to the server from their machines or the web server installed on a different machine. In that case, the following restrictive grant syntax should be considered: mysql> GRANT SELECT, INSERT ON mydb.* TO 'someuser'@'somehost'; 3. Disable the use of LOCAL INFILEThe next change is to disable the use of the “LOAD DATA LOCAL INFILE” command, which will help to prevent unauthorized reading from local files. This is especially important when new SQL Injection vulnerabilities in PHP applications are found. In addition, in certain cases, the “LOCAL INFILE” command can be used to gain access to other files on the operating system, for instance “/etc/passwd”, using the following command: mysql> LOAD DATA LOCAL INFILE '/etc/passwd' INTO TABLE table. Or even simpler: mysql> SELECT load_file("/etc/passwd")To disable the usage of the “LOCAL INFILE” command, the following parameter should be added in the [mysqld] section of the My. SQL configuration file. Change root username and password. The default administrator username on the My. SQL server is “root”. Hackers often attempt to gain access to its permissions. To make this task harder, rename “root” to something else and provide it with a long, complex alphanumeric password. To rename the administrator’s username, use the rename command in the My. SQL console: mysql> RENAME USER root TO new_user; The My. SQL “RENAME USER” command first appeared in My. SQL version 5. 0. If you use an older version of My. SQL, you can use other commands to rename a user: mysql> use mysql; mysql> update user set user="new_user" where user="root"; mysql> flush privileges; To change a user’s password, use the following command- line command: mysql> SET PASSWORD FOR 'username'@'%hostname' = PASSWORD('newpass'); It is also possible to change the password using the “mysqladmin” utility: shell> mysqladmin - u username - p password newpass. Remove the “test” database. My. SQL comes with a “test” database intended as a test space. It can be accessed by the anonymous user, and is therefore used by numerous attacks. To remove this database, use the drop command as follows: mysql> drop database test; Or use the “mysqladmin” command: shell> mysqladmin - u username - p drop test. Remove Anonymous and obsolete accounts. The My. SQL database comes with some anonymous users with blank passwords. As a result, anyone can connect to the database To check whether this is the case, do the following: mysql> select * from mysql. In a secure system, no lines should be echoed back. Another way to do the same: mysql> SHOW GRANTS FOR ''@'localhost'; mysql> SHOW GRANTS FOR ''@'myhost'; If the grants exist, then anybody can access the database and at least use the default database“test”. Check this with: shell> mysql - u blablabla. To remove the account, execute the following command: mysql> DROP USER ""; The My. SQL “DROP USER” command is supported starting with My. SQL version 5. 0. If you use an older version of My. SQL, you can remove the account as follows: mysql> use mysql; mysql> DELETE FROM user WHERE user=""; mysql> flush privileges; 7. Lower system privileges; increase database security with Role Based Access Control. A very common database security recommendation is to lower the permissions given to various parties. My. SQL is no different. Typically, when developers work, they use the system’s maximum permission and give less consideration to permission principles than we might expect. This practice can expose the database to significant risk.* Any new My. SQL 5. x installation already installed using the correct security measures. To protect your database, make sure that the file directory in which the My. SQL database is actually stored is owned by the user “mysql” and the group “mysql”. In addition, ensure that only the user “mysql” and “root” have access to the directory/var/lib/mysql. The mysql binaries, which reside under the /usr/bin/ directory, should be owned by “root” or the specific system “mysql” user. Other users should not have write access to these files. Lower database privileges. Operating system permissions were fixed in the preceding section. Now let’s talk about database permissions. In most cases, there is an administrator user (the renamed “root”) and one or more actual users who coexist in the database. Usually, the “root” has nothing to do with the data in the database; instead, it is used to maintain the server and its tables, to give and revoke permissions, etc. On the other hand, some user ids are used to access the data, such as the user id assigned to the web server to execute “select\update\insert\delete” queries and to execute stored procedures. In most cases, no other users are necessary; however, only you, as a system administrator can really know your application’s needs. Only administrator accounts need to be granted the SUPER / PROCESS /FILE privileges and access to the mysql database. Usually, it is a good idea to lower the administrator’s permissions for accessing the data.
