PHP, a nested abbreviation name, is the abbreviation of English Hypertext Preprocessing Language (PHP: Hypertext Preprocessor). PHP is an HTML embedded language. PHP is quite similar to Microsoft's ASP. Both are scripting languages that are embedded in HTML documents and are executed on the server side. The style of the language is similar to C language. It is now used by many It is widely used by website programmers. PHP's unique syntax is a mix of C, Java, Perl, and PHP's own innovative syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, dynamic pages made with PHP embed the program into the HTML document for execution, and the execution efficiency is much higher than CGI that completely generates HTML tags; compared with the scripting language JavaScript, which is also embedded in the HTML document In contrast, PHP is executed on the server side, taking advantage of the server's performance; the PHP execution engine will also store PHP programs that users frequently access in memory, and other users do not need to compile the program when they access this program once. Just execute the code in the memory directly, which is also one of the manifestations of PHP's high efficiency. PHP has very powerful functions. All CGI or JavaScript functions can be implemented by PHP, and it supports almost all popular databases and operating systems.

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
