Quick Answer

Handle exceptions before they reach global scope.

Understanding the Issue

This error occurs when an exception is thrown but not caught by any try/catch block.

The Problem

This code demonstrates the issue:

Php Error 
function risky() {
    throw new Exception("Error");
}
risky(); // Uncaught

The Solution

Here's the corrected code:

Php Fixed 
// Solution 1: Basic try-catch
try {
    risky();
} catch (Exception $e) {
    error_log($e->getMessage());
    echo "Caught exception";
}

// Solution 2: Global handler
set_exception_handler(function($e) {
    error_log("Uncaught: " . $e->getMessage());
    http_response_code(500);
});

// Solution 3: Specific exception types
try {
    risky();
} catch (InvalidArgumentException $e) {
    // Specific handling
} catch (Exception $e) {
    // Fallback handling
}
