1. Use eager loading to reduce the number of database queries Eager loading is a technique that allows you to load related models in a single query, reducing the number of queries needed to retrieve data.
Eager loading is a way to reduce the number of database queries in Laravel. It allows you to load related models in a single query, reducing the number of queries needed to retrieve data.
Node.js, PHP, and Go are three of the most popular programming languages used in web development today. Each language has its own strengths and weaknesses, making it important to understand the differences between them before deciding which one is right for your project.
I have set up the github action to deploy laravel website using appleboy ssh-action but all actions failed with this weird error message.
2022/09/03 23:46:24 ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain The fix is simple. just change the permission of authorized-keys by this command.
chmod 700 ~/.ssh/authorized_keys If it works, share it with a friend or colleage.
adding search box to header.php We would like to add that search field in the upper right area of the site, so what theme file do you think we might target to make modifications? That’s right, we’ll need to open up the header.php file and figure out a way to add some search functionality. We can do this with the built-in get_search_form() function, and also adding just a bit of CSS styling rules to the style.
Compiled language vs Scripting language Compiled code is faster than scripts with order of magnitude. Even after using a Just-in-time (JIT) compiler for PHP 7.4 and PHP 8 , PHP still slower than Go. Go is a clear winner.
Concurrency Go has concurrency as a built-in first class citizen. But PHP is good old language with no concurrency or parallelism in mind. The parallelism is achieved by executing scripts as a different process.
Laravel is a framework for backend development for websites. It is written in PHP programming language. We use PHP to write website backend code in Laravel framework.
A list of operators on Eloquent’s where() method When you use Eloquent’s where() method, by default it will use the = operator (i.e. ->where('fieldname','value') will generate ... WHERE fieldname = 'value'....
However you are not limited to just =. You can do something like this:
laravel new project-name create a new folder named “project-name” in the current directory. Then create all necessary Laravel project files inside it.
composer require vendor/package update composer.json with the necessary details of the package you are choosing to install, then install the package in your project.
composer update update the installed packages.
composer dump-autoload updates your vendor/composer/autoload_classmap.php file. You have to run this command if you have a new class in your project that has not yet been loaded.

When I try to create database in phpMyAdmin. This error show up access denied for user 'user'@'localhost' to database 'db'. and there is no buttons to create database in phpMyAdmin page.
On CPanel, we can’t create database in phpMyAdmin directly so security reasons. So the fix is to create MySQL database via CPanel not in phpMyAdmin. So, when using CPanel we create Database using Database Wizard as you see in this video.
