Introduction: Merge arrays The array_merge() function merges arrays together and returns a combined array. The resulting array starts with the first input array parameter, and is added sequentially in the order in which subsequent array parameters appear. Its form is: 1 array array_merge (array array1 array2...,arrayN) Merges the cells of one or more arrays, and the values in one array are appended to the end of the previous array. Returns the resulting array. If there is the same string key name in the input array, the key name will be followed...

Methods to modify array elements in PHP include direct assignment and batch modification using functions. 1. For indexed arrays, such as $colors=['red','green','blue'], the second element can be modified by $colors[1]='yellow'. 2. For associative arrays, such as $person=['name'=>'John','age'=>30], the value of age can be modified by $person['age']=31. 3. Use array_map or array_walk functions to modify array elements in batches, such as $numbers=array_map(fun

Implementing hook functions in PHP can be implemented through observer mode or event-driven programming. The specific steps are as follows: 1. Create a HookManager class to register and trigger hooks. 2. Use the registerHook method to register the hook and trigger the hook by the triggerHook method when needed. Hook functions can improve the scalability and flexibility of the code, but pay attention to performance overhead and debugging complexity.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
