What are PHP Errors and How to Handle Them?
Understanding PHP Errors: PHP errors are issues that occur during the execution of a script, which can range from syntax errors to runtime errors. These errors can disrupt the normal flow of the script and affect the overall functionality of the application. Understanding the nature and types of PHP errors is essential for effective error handling and resolution.
Types of Errors and Error Levels: PHP categorizes errors into different levels, such as notices, warnings, and fatal errors. Each error level indicates the severity of the issue, and understanding these levels is crucial for prioritizing and addressing errors effectively.
Custom Error Handling Functions: PHP allows developers to create custom error handling functions to manage and handle errors based on specific requirements. Custom error handling functions provide flexibility in dealing with errors and can be tailored to suit the needs of the application.
What is Exception Handling in PHP?
Custom Exception Handler: Exception handling in PHP involves managing and addressing exceptional conditions or errors that disrupt the normal flow of the script. PHP provides a mechanism for creating custom exception handlers to handle exceptional situations and maintain the stability of the application.
