First, make sure you have installed and enabled the GD library, as both of these functions belong to the GD image processing library. You can check whether the GD library is enabled using the following code:

This article explores the common causes of errors related to the highlight_file() function in PHP error logs and offers practical solutions to fix them. It covers issues such as incorrect file paths, permission problems, non-PHP file formats, invalid URLs, return value handling, and PHP configuration settings.

The strpos function in PHP is used to find the position of the first occurrence of a substring within another string. If the target substring is not found, strpos returns false. However, because false is treated as a "falsy" value in PHP, this can cause confusion—especially when developers mistake a return value of 0 (which means the substring is found at the start) as false. This article explores why strpos returns false, common pitfalls, and how to properly handle its return value.

As PHP projects grow increasingly large, performance optimization has become a key focus for developers. Among various optimization methods, properly configuring the realpath_cache_size parameter can significantly enhance the efficiency of filesystem operations. This is especially important in large PHP projects when handling file paths and includes. This article explores how to improve overall performance in large PHP projects by optimizing realpath_cache_size.

In PHP development, session management is a crucial part of building dynamic websites. Through session management, developers can easily track user states and data. PHP offers multiple functions to handle session management, among which the session_register() function was commonly used in earlier PHP versions. However, with the release of PHP 5.4 and later versions, session_register() has been deprecated and is no longer recommended. Nonetheless, understanding the basic usage of session_register() remains meaningful for legacy projects or beginners learning PHP session management.

When working with XML files in PHP, xml_set_external_entity_ref_handler and libxml_disable_entity_loader are two commonly used functions. They are used for handling external entities and disabling external entity loading, respectively. However, using them together can lead to compatibility issues, especially when dealing with XML files that include external DTDs and entities. This article explores the root causes of these issues and provides practical solutions.
