This article explains how to develop high-performance PHP7/8 extensions using C++. By combining C++'s powerful computational capabilities with PHP's flexibility, developers can create efficient and scalable PHP extensions. The article provides detailed guidance on the process, including setting up the development environment, code examples, and installation steps to help developers enhance PHP application performance.

In PHP, arrays are one of the most commonly used data structures. When working with arrays, we often rely on built-in functions to simplify our code, such as array_map() and reset(). While these two functions might seem unrelated at first glance, they can be used together effectively in real-world scenarios to write cleaner and more efficient logic. This article dives into a practical case study to demonstrate how they can be combined, helping you better master PHP array handling techniques.

The key to optimization lies in this: if you only need the maximum value and not the full mapping result, the logic can be executed in a single loop.

The settype() function is a built-in feature in PHP used to change the type of a variable. It directly modifies the variable’s type and returns a boolean value indicating whether the conversion was successful. Here’s a common example:

In PHP, array_filter and array_map are two very commonly used and powerful array processing functions. They have their own uses when used alone, but when we combine them, we can greatly improve the simplicity and efficiency of the code. This article will introduce the usage of these two functions in detail and share practical tips and best practices for their combination.

The ord() function returns the ASCII value of a character, while the array_map() function can be used to apply a callback function to every element in an array. When we need to process each character in a string in bulk and obtain their ASCII values, these two functions can be combined. This article will explain in detail how to achieve this functionality.

Typical Use Cases of PHP array_values Combined with array_map

The realpath() function is used to resolve a given file path and return its absolute path. When realpath() is called multiple times, PHP will cache the resolved file paths by default to avoid redundant calculations, thus improving performance. The realpath_cache_size is used to control the size of this cache.

Discover the best method to use arsort with array_map in PHP to achieve efficient and flexible complex data sorting, especially for multidimensional arrays and conditional sorting.

array_map is a very practical function that can apply a specified callback function to each element of the array, thereby batch processing of array data. cosh (hyperbolic cosine function) is one of the common functions in mathematics, used to calculate the hyperbolic cosine value of a given value.

First, we connect to the FTP server through ftp_connect and ftp_login. Then use ftp_rawlist to get the original file list of the remote directory.

During PHP development, we often need to process some elements in an array instead of traversing the entire array. To achieve this, array_slice and array_map are two very useful functions. This article will explain in detail how to use them in combination to enable efficient processing of a part of an array, and illustrate it with actual code examples.

In daily PHP programming, we often need to sort string arrays, but the default dictionary sorting (sort, usort, etc.) does not handle strings with numbers well. For example, if file names such as img1.png, img2.png, img10.png are compared with ordinary strings, the sorting result will be img1.png, img10.png, img2.png, which obviously does not conform to human natural sorting habits.
