PHP Error Reporting

Types of PHP Error

PHP errors can be classified into three main categories:

Syntax errors: Whenever there is an error in the syntax of the PHP code, it is known as a syntax error. It may occur due to a missing semicolon, brackets, etc.
 

Runtime errors: The errors that occur during execution are known as PHP errors. It may occur due to access to an undefined variable or a wrong call to a function.
 

Logical errors: This type of PHP error occurs when there is an error in the logic of the PHP code, which results in unexpected outputs.

PHP error reporting 

PHP error reporting is a powerful built-in function in PHP that allows developers to identify and fix runtime, syntax, and logical errors. These errors in PHP are categorized into different levels. The error_reporting() function manages the reporting of php errors at different levels.

The PHP error reporting function lets developers see error messages and warnings corresponding to the source of the error.

The function sets the error_reporting directive at runtime based on the specification in the php.ini file.
