PHP can be used to perform common database operations such as inserting, viewing, updating, and deleting records. It can also be used to upload images and store their file names in a database.<\/p>\n\n\n\n
In this article, we will explain how to perform basic INSERT, VIEW, UPDATE, and DELETE operations<\/strong> on a MySQL database using PHP, along with a basic example of image upload.<\/p>\n\n\n\n Before proceeding, make sure you have:<\/p>\n\n\n\n First, create a database named The INSERT operation is used to add a new record to the database.<\/p>\n\n\n\n The PHP code accepts the values submitted through the form and uploads the selected image to the The HTML form should use The SELECT query is used to retrieve records from the database.<\/p>\n\n\n\n The VIEW page fetches the records from the The UPDATE operation is used to modify an existing record.<\/p>\n\n\n\n The record ID is passed through the URL, the existing information is retrieved, and the submitted values are used to update the corresponding record.<\/p>\n\n\n\n The DELETE operation is used to remove a record from the database.<\/p>\n\n\n\n The record ID is passed through the URL, and the corresponding record is deleted from the The example above uses the older PHP For new applications, it is recommended to use MySQLi<\/strong> or PDO<\/strong> with prepared statements. Passwords should also be securely hashed instead of storing them as plain text.<\/p>\n\n\n\n For image uploads, validate the file type and size before saving the file to the server.<\/p>\n\n\n\n In this article, we explained how to perform basic database operations using PHP, including insert, view, update, and delete<\/strong>. We also covered how to upload an image and store its file name in a database.<\/p>\n\n\n\n These operations form the basic foundation of many PHP-based applications. For production applications, modern database APIs, prepared statements, password hashing, and secure file-upload validation should be used.<\/p>\n\n\n\n The basic database operations are INSERT, SELECT, UPDATE, and DELETE<\/strong>, commonly referred to as CRUD operations.<\/p>\n\n\n\n An image can be uploaded using an HTML form with In this example, the uploaded image is stored in the How to drop a database in postgreSQL ? – Pheonix Solutions<\/a><\/p>\n\n\n\nPrerequisites<\/h2>\n\n\n\n

Implementation<\/h2>\n\n\n\n
Step 1: Create the Database and Table<\/h3>\n\n\n\n
demo<\/code> and a table named reg<\/code> to store the user details.<\/p>\n\n\n\nCREATE DATABASE demo;\n\nCREATE TABLE reg (\n id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,\n name VARCHAR(30) NOT NULL,\n password VARCHAR(30) NOT NULL,\n address VARCHAR(30) NOT NULL,\n email VARCHAR(50),\n fathername VARCHAR(30) NOT NULL,\n mothername VARCHAR(30) NOT NULL,\n country VARCHAR(50),\n state VARCHAR(30) NOT NULL,\n city VARCHAR(50),\n photo VARCHAR(50)\n);\n<\/pre>\n\n\n\n
Step 2: Insert Data and Upload an Image<\/h3>\n\n\n\n
upload<\/code> directory. The image file name is then stored in the database.<\/p>\n\n\n\n\/\/ Insert code\n<\/pre>\n\n\n\n
enctype=\"multipart\/form-data\"<\/code> when uploading files.<\/p>\n\n\n\n<form action=\"\" method=\"post\" enctype=\"multipart\/form-data\">\n<\/pre>\n\n\n\n
Step 3: View Records<\/h3>\n\n\n\n
reg<\/code> table and displays the user information in a table. It also provides Edit<\/strong> and Delete<\/strong> links for each record.<\/p>\n\n\n\n\/\/ View code\n<\/pre>\n\n\n\n

Step 5: Delete Records<\/h3>\n\n\n\n
