In development, processing multidimensional array data returned by an API is a common task. Particularly when we need to extract a specific field from the returned complex data and analyze the most common values of that field, PHP's array_column function is highly efficient and straightforward.

Using PDOStatement::columnCount to Implement Interface Output Structure Consistency Testing: What Are Some Practical Tips?

The array_combine function can be used to merge the keys and values of two arrays into an associative array. It is particularly useful when you need to combine the key-value pairs from two configuration files into a complete configuration array.

The array_diff_uassoc function is used to compare two arrays and returns an array containing the key differences. When we need to read an array from a CSV file and compare the keys with those in an original array, array_diff_uassoc is a very useful tool. This article will explain in detail how to use this function to compare key differences between an array read from a CSV file and an original array.

In PHP programming, magic constants are highly useful as they provide dynamic information during program execution, such as the current file path, line number, etc. Common magic constants include FILE, DIR, and LINE. However, in most cases, it is not possible to directly retrieve the values of these magic constants through traditional constant methods. This article introduces a workaround approach using the get_defined_constants function to retrieve the values of magic constants in PHP.

array_diff_ukey() is a function used to compare the keys of two or more arrays and return the keys that do not exist in the other arrays. This function allows passing a custom callback function for custom comparison operations. However, if the callback function’s parameter order is incorrect, it may cause the comparison results to be unexpected.

We often need to construct complex multidimensional arrays. With PHP’s built-in functions array_fill() and array_merge(), we can efficiently achieve this task. Today, we’ll explore how to use these two functions to quickly build a complex multidimensional array.
