Typecho is a simple and efficient open source blog system, written in PHP language, with flexible scalability and excellent performance. When using Typecho to develop websites, mastering some PHP programming skills can help us develop and customize themes more efficiently. This article will share several common PHP programming techniques and attach corresponding code examples.

1. Use php.ini file for configuration

In Typecho development, we often need to modify PHP configuration information, such as modifying upload file size limits, setting time zones, etc. At this time, it can be achieved by modifying the php.ini configuration file. In the root directory of Typecho, you can find the php.ini file and modify it. For example, to set the upload file size limit to 10MB, you can add the following code to the php.ini file:

upload_max_filesize = 10M post_max_size = 10M

2. Using Typecho’s hook function

Typecho provides a rich The hook function can help us insert custom code at specific locations to extend and customize Typecho. Commonly used hook functions include "Widget_Archive_After", "Widget_Archive_Before" and "Widget_Abstract_Contents". The following is a sample code that uses a hook function to display copyright information at the end of the article:

is('single')): ?>  

3. Using Typecho’s dynamic function

The dynamic function is a function unique to Typecho , which can automatically generate URLs based on function names, making URL construction more concise and semantic. The most commonly used dynamic functions include "widget", "permalink" and "tag". The following is a sample code that uses dynamic functions to generate category page links:

 name(); ?> 

4. Using Typecho’s built-in functions

Typecho has many built-in practical functions that can help us deal with it Common tasks such as string manipulation, time formatting, etc. Commonly used built-in functions include "nl2br", "str_replace" and "date". Here is a sample code that uses built-in functions to convert newline characters to
tags:

content; ?> 

5. Using Typecho's database operation class

Typecho provides database operations Class, you can easily perform database reading and writing operations. By using database operation classes, we can add, delete, modify, and query data in the Typecho database. The following is a sample code that uses the database operation class to query the number of articles:

getPrefix(); $count = $db->fetchObject($db->select('COUNT(cid) AS count') ->from($prefix . 'contents') ->where('status = ?', 'publish') ->where('type = ?', 'post')); echo $count->count; ?>

The above are some PHP programming techniques commonly used in Typecho. I hope it will be helpful to you when developing and customizing Typecho themes. By using these techniques flexibly, we can achieve our needs more efficiently and provide users with a better experience. Of course, there are more techniques waiting for us to explore and apply. I wish you go further and further on the development road of Typecho!
