关于php扩展编程如何返回数组的问题_PHP
在zend.com找到了答案，提供了一组例子，这里下载：http://www.zend.com/apidoc/examples.tar.gz
这样返回一个数组
PHP_FUNCTION(array_experiments)
{
zval *new_element;
MAKE_STD_ZVAL(new_element);
array_init(return_value);
ZVAL_LONG(new_element, 10);
zend_hash_index_update(HASH_OF(return_value), 3, (void *)&new_element, sizeof(zval *), NULL);
add_next_index_long(return_value, 20);
}
具体函数参见php手册 zend api部分 不过这部分的内容一直都没有翻译成中文的...看得时候好吃力，用金山词霸也看不懂，英文太烂了，期待那天那个高人没事儿给翻译了...呵呵

Extensions and third-party modules for PHP functions
Apr 13, 2024 pm 02:12 PM
To extend PHP function functionality, you can use extensions and third-party modules. Extensions provide additional functions and classes that can be installed and enabled through the pecl package manager. Third-party modules provide specific functionality and can be installed through the Composer package manager. Practical examples include using extensions to parse complex JSON data and using modules to validate data.
Remove duplicate values from PHP array using regular expressions
Apr 26, 2024 pm 04:33 PM
How to remove duplicate values from PHP array using regular expressions: Use regular expression /(.*)(.+)/i to match and replace duplicates. Iterate through the array elements and check for matches using preg_match. If it matches, skip the value; otherwise, add it to a new array with no duplicate values.
How do the types of PHP function return values relate to the interoperability of PHP extensions?
Apr 15, 2024 pm 09:06 PM
PHP function return value types can be expressed as type description syntax, which clearly specifies the return value type of each function. Understanding return value types is critical to creating extensions that are compatible with the PHP core engine, avoiding unexpected conversions, improving efficiency, and enhancing code readability. Specifically, extension functions can define a return value type so that the PHP engine can optimize code execution based on that type and allow developers to explicitly handle the return value. In practice, extension functions can return PHP objects, and PHP code can handle the returned results according to the return value type.
What is programming for and what is the use of learning it?
Apr 28, 2024 pm 01:34 PM
1. Programming can be used to develop various software and applications, including websites, mobile applications, games, and data analysis tools. Its application fields are very wide, covering almost all industries, including scientific research, health care, finance, education, entertainment, etc. 2. Learning programming can help us improve our problem-solving skills and logical thinking skills. During programming, we need to analyze and understand problems, find solutions, and translate them into code. This way of thinking can cultivate our analytical and abstract abilities and improve our ability to solve practical problems.

Demystifying C: A Clear and Simple Path for New Programmers
Oct 11, 2024 pm 10:47 PM
C is an ideal choice for beginners to learn system programming. It contains the following components: header files, functions and main functions. A simple C program that can print "HelloWorld" needs a header file containing the standard input/output function declaration and uses the printf function in the main function to print. C programs can be compiled and run by using the GCC compiler. After you master the basics, you can move on to topics such as data types, functions, arrays, and file handling to become a proficient C programmer.
