The seven magic constants of PHP are __LINE__, __FILE__, __DIR__, __FUNCTION__, __CLASS__, __TRAIT__, __METHOD__, and they can dynamically return code location and context information, 1. LINE returns the current line number, for precise debugging; 2. FILE returns the absolute path of the current file, often used to reliably introduce files or define root directory; 3. DIR returns the directory where the current file is located, which is clearer and more efficient than dirname (__FILE__); 4. FUNCTION returns the current function name, suitable for function-level log tracking; 5. CLASS returns the current class name (including namespace), in logs and factories

Using === instead of == is the key to avoid PHP type conversion errors, because == will cause unexpected results, and === compare values and types at the same time to ensure accurate judgment; for example, 0=="false" is true but 0==="false" is false, so when dealing with return values that may be 0, empty strings or false, === should be used to prevent logical errors.

To eliminate the complexity of nested if statements, you should use the guard clause to return in advance, merge conditional expressions, replace branches with polymorphic or policy patterns, and use lookup table mapping values; 1. Use the guard clause to process boundary conditions in advance and exit; 2. Use logical operations to meet and related conditions; 3. Use polymorphic or policy patterns to replace complex type branches; 4. Use dictionaries and other data structures to replace simple conditional mapping; ultimately make the code flat and linear, improving readability and maintainability.

The =& operator of PHP creates variable references, so that multiple variables point to the same data, and modifying one will affect the other; 2. Its legal uses include returning references from a function, processing legacy code and specific variable operations; 3. However, it is easy to cause problems such as not releasing references after a loop, unexpected side effects, and debugging difficulties; 4. In modern PHP, objects are passed by reference handles by default, and arrays and strings are copied on write-time, and performance optimization no longer requires manual reference; 5. The best practice is to avoid using =& in ordinary assignments, and unset references in time after a loop, and only use parameter references when necessary and document descriptions; 6. In most cases, safer and clear object-oriented design should be preferred, and =& is only used when a very small number of clear needs.

preg_replace_callback is a powerful tool in PHP for dynamic string replacement, which implements complex logic by calling custom functions for each regular match. 1. The function syntax is preg_replace_callback($pattern,$callback,$subject), where $callback can dynamically process the matching content; 2. It can be used for numerical transformation, such as replacing [10] with [20]; 3. Supporting multi-capture group operations, such as converting the YYYY-MM-DD format date to "May15,2024"; 4. Combining the use keyword can maintain the status, such as adding an incremental number to each word; 5. Applicable to

Data must be properly escaped at each layer during the transfer from the database to the user's browser to prevent security vulnerabilities. 1. Database layer: Use parameterized queries to prevent SQL injection and avoid string splicing; 2. Server layer: Input needs to be verified and cleaned, and output is escaped according to the context, such as HTML entity encoding, JavaScript string escape, URL encoding, etc., and priority is given to the use of built-in escape functions of the framework; 3. API layer: Use built-in methods such as JSON.stringify or json_encode to serialize data, and enable JSON_HEX_TAG and other flags to prevent XSS; 4. Front-end layer: avoid innerHTML inserting unfiltered user data, and use textCo

DIR and FILE are magic constants in PHP, which can effectively solve file inclusion errors caused by relative paths in complex projects. 1.FILE returns the full path of the current file, and __DIR__ returns its directory; 2. Use DIR to ensure that include or require is always executed relative to the current file, avoiding path errors caused by different call scripts; 3. It can be used to reliably include files, such as require_onceDIR.'/../config.php'; 4. Define BASE_DIR constants in the entry file to unify project path management; 5. Load configuration files safely, such as $config=requireDIR.'/config/dat
