1. How Can PHP Search MySQL Table Fields with Large Text Fields Using the MySQL FIND_IN_SET Function

Updated on: 2022-06-28

Blog: Advanced PHP MySQL Search Controller package blog
Package: Advanced PHP MySQL Search Controller

Many PHP developers use MySQL as a database to store application information dynamically.

PHP developers often need to perform search queries to filter the database table records with field values matching given criteria. Sometimes there is the need to filter records that match multiple criteria.

SQL allows composing complex search queries to combine multiple search criteria.

MySQL has a particular function named FIND_IN_SET that allows defining a condition that can check if string values have a given number of occurrences of another string value.

This class allows composing complex MySQL search queries that combine multiple search conditions. Some conditions can use the FIND_IN_SET function to find database table records with particular values in larger text fields.

This possibility allows PHP developers to perform complex searches to find given text values inside database table field values that have text values the PHP application users want to see.

1. How to Implement a Laravel OAuth2 Server API that Can Refresh Expired OAuth Tokens Automatically

Updated on: 2022-06-23

Posted on:

Blog: Laravel Passport Auth Proxy package blog
Package: Laravel Passport Auth Proxy

Laravel Passport is a package intended to provide user authentication for APIs using the OAuth 2 protocol.

An OAuth 2-based API server can generate tokens for the API clients to access the API on behalf of a real human user who authorizes the access to the API services from API client programs.

An OAuth 2 server can generate access tokens that it returns to the API client program. In the subsequent request that the client program sends to the API server, the client only needs to pass a token value to authenticate on behalf of the same user.

API servers should renew the access tokens after some time to improve the security of the API access.

This package provides a service that can perform the renewal of access tokens using refresh tokens by following the procedure determined by the OAuth 2 protocol specification.

This package can make the OAuth 2-based APIs based on the Laravel Passport more secure.

1. How Can PHP Parse JSON Data from a Post Request in a Secure Way to Avoid Hash DoS Attacks

Updated on: 2022-06-16

Posted on:

Blog: iaso PHP JSON Parser Library package blog
Package: iaso PHP JSON Parser Library

A Hash DoS attack is a security attack that may affect PHP applications that use arrays or objects to pass parameters from clients to PHP using HTTP request variables.

This vulnerability may affect PHP versions that do not avoid collisions of hash data structures that may take many keys that result in the same hash value to determine how PHP's arrays and objects are stored internally.

PHP provides better alternative methods to store arrays and objects more immune to this vulnerability.

This package implements a parser for JSON strings that uses an alternative method to store values or JSON objects passed to PHP from HTTP requests like those used to call APIs implemented in PHP.
