Why is it important to properly debug PHP code and avoid suppressing error messages with the "@" symbol?

Properly debugging PHP code is essential for identifying and resolving errors in the code. Suppressing error messages with the "@" symbol can make it difficult to pinpoint the root cause of issues, leading to potential bugs going unnoticed. By allowing error messages to be displayed, developers can quickly identify and fix problems in their code, resulting in a more stable and reliable application.

// Before
@some_function(); // Error messages will be suppressed

// After
some_function(); // Error messages will be displayed for debugging
