PHP and Laravel are not directly comparable, because Laravel is a PHP-based framework. 1.PHP is suitable for small projects or rapid prototyping because it is simple and direct. 2. Laravel is suitable for large projects or efficient development because it provides rich functions and tools, but has a steep learning curve and may not be as good as pure PHP.
introduction
When we talk about programming languages and frameworks, PHP and Laravel are often discussed together. As a programming master, I am often asked which one is better: PHP or Laravel? In fact, these two are not directly comparable, because Laravel is a PHP-based framework. Today, we will explore the features, advantages and disadvantages of PHP and Laravel, and their applicability in different scenarios, hoping to help you make smarter choices.
Review of basic knowledge
PHP is a widely used server-side scripting language, especially suitable for web development. Its syntax is simple, easy to use, and has a huge community and rich resources. On the other hand, Laravel is a PHP-based framework designed to simplify the web development process, provide more structured code organization and higher development efficiency.
When using PHP, you can directly write scripts, handle HTTP requests, operate databases, etc. When using Laravel, you will use the MVC architecture, ORM system, routing system and other functions it provides to build applications.
Core concept or function analysis
The definition and function of PHP
PHP is a common scripting language suitable for server-side programming. It can be embedded in HTML, process form data, and generate dynamic web page content. The advantage of PHP is its flexibility and a wide range of application scenarios, from small websites to large enterprise applications.
A simple PHP script example:
<?php echo "Hello, World!"; ?>
This line of code will output "Hello, World!" to the browser.
The definition and function of Laravel
Laravel is a modern PHP framework designed to simplify web development with elegant syntax and rich features. It provides powerful tools and libraries, such as Eloquent ORM, Blade template engine, Artisan command line tools, etc., allowing developers to build complex applications faster.
A simple Laravel routing example:
Route::get('/', function () { return view('welcome'); });
This line of code defines a route that returns the welcome view when accessing the root path.
How it works
PHP works by interpreting execution scripts. The PHP engine parses PHP code, executes the logic therein, and generates HTML output. It executes faster, but requires developers to manage the code structure and security themselves.
Laravel's working principle is to provide a complete MVC architecture based on PHP. The request is first processed through the routing system, then processed by the controller, and finally returned the result through the view. Laravel also provides advanced functions such as middleware and service containers to help developers better manage applications.
Example of usage
Basic usage of PHP
The basic usage of PHP is very simple, and the following is an example of processing form data:
<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { $name = $_POST["name"]; echo "Hello, " . htmlspecialchars($name) . "!"; } ?> <form method="post" action="<?php echo $_SERVER["PHP_SELF"];?>"> Name: <input type="text" name="name"> <input type="submit"> </form>
This code will process a simple form that outputs the name entered by the user.
Advanced usage of Laravel
Advanced usage of Laravel includes using Eloquent ORM for database operations, and here is an example:
use App\Models\User; Route::get('/users', function () { $users = User::where('active', 1) ->orderBy('created_at', 'desc') ->take(10) ->get(); return view('users.index', ['users' => $users]); });
This code will query the database, get the last 10 active users, and pass it to the view.
Common Errors and Debugging Tips
Common errors when using PHP include SQL injection, XSS attacks, etc. You can prevent SQL injection by using mysqli
or PDO
and use htmlspecialchars
to prevent XSS attacks.
In Laravel, common errors include routing configuration errors, migration failures, etc. You can debug by using php artisan route:list
to view all routes and using php artisan migrate:status
to view migration status.
Performance optimization and best practices
In PHP, performance optimization can be started from cache, database query optimization, etc. For example, use APC
or Memcached
to cache data, and use EXPLAIN
to analyze SQL query performance.
In Laravel, performance optimization can utilize its built-in cache systems, queue systems, etc. For example, use Cache::remember
to cache query results and use Queue::push
to process tasks asynchronously.
In terms of programming habits and best practices, PHP developers should pay attention to the readability and security of the code and use object-oriented programming to improve the maintainability of the code. Laravel developers should follow the coding specifications they provide and use test-driven development (TDD) to ensure code quality.
In-depth insights and suggestions
When choosing PHP or Laravel, you need to consider the size and complexity of the project. For small projects or rapid prototyping, PHP may be more suitable because it is simple and straightforward and easy to get started. For large projects or scenarios that require efficient development, Laravel is a better choice because it provides a wealth of features and tools to help developers build complex applications faster.
However, Laravel also has some potential drawbacks, such as a steep learning curve and may not be as high as pure PHP. Therefore, when using Laravel, it is necessary to weigh the convenience it brings with the possible performance losses.
In short, PHP and Laravel each have their own advantages, and which one to choose depends on your specific needs and project goals. I hope this article can provide you with valuable reference and help you make smarter choices.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
