How can error handling be improved by removing the "@" symbol before function calls in PHP?

When the "@" symbol is used before function calls in PHP, it suppresses any errors or warnings that may occur during the execution of that function. This can make debugging and error handling more challenging as issues are not reported. By removing the "@" symbol, errors and warnings will be displayed, allowing for better error handling and troubleshooting.

// Before
@function_call();

// After
function_call();
