I often feel drained of talent,In fact, I can’t say that I am talented,I knew when I was very young that I have no talent in any aspect,So I have to be old all my life The scalper's spirit, works silently and moves forward slowly,When you are unlucky, you may be like many of your fathers and go through this life in obscurity and boredom,If you are lucky, maybe you can still... Shine some light in a certain small area in a certain small field,I am like many colleagues, eager to break through and eager to shine,People should always maintain a positive and enterprising state of moving forward,this It is to prepare for the emergence of opportunities,Even if there is no chance, you can maintain this state,Your work and life should be VERY GOOD, When I first started working,When I encountered failures and setbacks, I always liked to be pessimistic and self-doubt,I even complained about all kinds of things,The results were often very... GroundTERRIBLE, not only damages self-confidence,, but also causes a series of bad states,, causing work and life to be adversely affected for a period of time....
After experiencing some bigger failures,My habit of complaining about myself has been corrected,My concept has also been upgraded to a certain extent, It seems like when you just started to learn to ride a bicycle, you rode up again and again, only to fall off again and again,you kept repeating the same mistakes.... ..Suddenly one day,You no longer fall,You can ride away slowly,The wheels start to turn.It’s like there’s a wave The magical force helps you , and your eyes open up . It should be the magic you discover in your mistakes.Behind every mistake you make, there will be something hidden With a magical power. Therefore, the more mistakes we make, the more time we will spend learning, the more we will absorb and learn from making mistakes, the faster we will progress, and the more likely we will be in our lives. More miracles. Therefore, when we deal with every mistake, we become more optimistic, wise, brave and decisive, and we should not be depressed, because we gain more and richer valuable experience from it.
However, in school you may be considered a smart student because you make no mistakes, but in life, you are smart precisely because you have made mistakes and learned from them. It can be seen that life should be the most severe teacher.
Successful people are successful because they are more willing than others to make mistakes and learn from them. Most people either don't want to make mistakes, or they make the same mistakes over and over again without ever realizing why. If you don't have enough experience of making mistakes, or if you don't learn from your mistakes, then miracles are destined to not happen in your life.

The above introduces how programmers face errors? , including relevant content, I hope it will be helpful to friends who are interested in PHP tutorials.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
