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.
I faced this error parse error : syntax error, unexpected "." , expecting "&" or variable (T_VARIABLE) in wp-include/functions.php on line 1081. This error is because there is two PHP versions loaded on the modules. So we should comment out one of them. So I commented out the php5 module. And everything worked fine. First step, edit the httpd.conf file using this command. sudo nano /etc/apache2/httpd.conf Then add a # in front of the php5 module (or one of the two versions of PHP you have).
First, “web development” is a very broad term and might, therefore, mean a lot of things including server-side rendered HTML pages, JSON APIs, microservices, etc. Second, let’s define what makes a programming language qualify for web development. (sorted by importance) Ecosystem Tooling Libraries Developer market Success stories Maintainability Language design Ecosystem consistency Performance Asynchronous execution for increased throughput Low latency Raw number-crunching performance Infrastructure Hosting and deployment Memory usage and cost in general So, let’s get ready to compare!
