What is the significance of removing the "@" symbol before function calls in PHP code?

Removing the "@" symbol before function calls in PHP code is significant because it suppresses error messages and warnings that may occur during the execution of the function. This can make debugging and troubleshooting more difficult as errors are not displayed. It is generally recommended to address the root cause of the errors instead of simply suppressing them with the "@" symbol.

// Before
@$result = someFunction();

// After
$result = someFunction();
