Calling cosh in WordPress plugin to implement math extension

During the development of WordPress plug-in, sometimes we need to extend mathematical functions to meet certain complex computing needs. PHP itself provides a rich library of mathematical functions, where the cosh function is used to calculate hyperbolic cosine, which is a function commonly used in many engineering and scientific calculations.

This article will introduce how to call PHP's cosh function in WordPress plug-in, and combine simple examples to help developers quickly grasp its usage.

What is a cosh function?

cosh is a hyperbolic cosine function defined as:

It is one of the common hyperbolic functions and is widely used in fields such as physics, engineering, and computer science.

PHP provides a built-in cosh() function that can directly calculate the hyperbolic cosine value of a number.

Calling cosh function in WordPress plugin

The WordPress plug-in is essentially a PHP script, so you can use PHP's mathematical functions directly. Here is a simple example showing how to call cosh functions in a plug-in and display the calculation results through short code.

1. Create the plugin main file

Create a new plug-in file, such as cosh-extension.php , and write the following code:

 <?php
/*
Plugin Name: Cosh Function Extension
Description: exist WordPress Called in the plugin PHP cosh function，Implement mathematical extension function。
Version: 1.0
Author: Your Name
*/

// Register a short code [cosh_calc value="number"]
function cosh_calc_shortcode($atts) {
    // Get the incoming value parameter，The default is 0
    $atts = shortcode_atts(array(
        'value' => 0,
    ), $atts, 'cosh_calc');

    $input = floatval($atts['value']);
    $result = cosh($input);

    return "cosh({$input}) The calculation result is：{$result}";
}
add_shortcode('cosh_calc', 'cosh_calc_shortcode');

2. Plug-in Description

• The plugin registers a short code [cosh_calc value="number"] .

• Calculate the hyperbolic cosine value of the passed number through the cosh() function.

• Returns the result to be displayed on the page.

3. How to use

After enabling the plugin, insert shortcodes into your WordPress page or article, for example:

 [cosh_calc value="1.5"]

The page will display:

 cosh(1.5) The calculation result is：2.35240961524325

Extended application

You can combine JavaScript or Ajax to implement dynamic computing functions and improve user experience. At the same time, function calls can be encapsulated into class methods for easy maintenance and extension.

For example, encapsulated as a class:

 <?php
class Math_Extension {
    public static function cosh_value($x) {
        return cosh($x);
    }
}

Then in the shortcode call:

 $result = Math_Extension::cosh_value($input);
