How can PHP developers effectively handle different types of errors, such as technical issues versus user input errors, in their code?

When handling different types of errors in PHP, developers can use try-catch blocks to handle exceptions for technical issues, and conditional statements to validate and handle user input errors. By separating the error handling logic based on the type of error, developers can effectively manage and troubleshoot issues in their code. 

try {
    // Code that may throw technical errors
    // For example, database connection failure
} catch (Exception $e) {
    // Handle technical errors here
    echo "An error occurred: " . $e->getMessage();
}

$userInput = $_POST['user_input'];

if (!is_numeric($userInput)) {
    // Handle user input error for non-numeric input
    echo "Please enter a valid number";
} else {
    // Process the user input
    $result = $userInput * 2;
    echo "Result: " . $result;
}
