PHP SQL Insert
PHP SQL Insert is used to insert the record from HTML page to Mysql database using PHP.
Understand with Example
The Tutorial illustrate an example from PHP SQL Insert . To understand the example, firstly we need to create a table 'stu' with required fieldnames and datatypes respectively. The table 'stu' has a Primary Key 'id'.
Create Table Stu:
CREATE TABLE `stu` (
`id` int(11) NOT NULL auto_increment,
`name` varbinary(10) default NULL,
`class` int(11) default '12',
PRIMARY KEY (`id`)
)
Insert.php:
We create an HTML form that is used to add the new records to table 'stu' in Mysql database. When a user click on a submit button of html page,the form records is sent to the "insert.php". The insert.php is connected to the database and submit the records from HTML page with PHP post variable. The Mysql insert query in PHP execute the query and add the records to the table 'Stu'.
