What is the significance of using E_ALL when debugging PHP code?

Using E_ALL when debugging PHP code allows all error types to be displayed, making it easier to identify and fix issues in the code. This can help catch syntax errors, undefined variables, and other common mistakes that may not be immediately obvious. By enabling E_ALL, developers can ensure that all potential errors are being reported, leading to more robust and reliable code.

error_reporting(E_ALL);
ini_set('display_errors', 1);
