Exceptions in PHP (Try/Catch Like a Pro)

Exceptions make error handling cleaner than checking return values everywhere.

Basic try/catch

try {
  if ($amount <= 0) {
    throw new Exception("Amount must be positive");
  }
  echo "OK";
} catch (Exception $e) {
  echo $e->getMessage();
}

Custom exception example

class PaymentFailedException extends Exception {}

function chargeCard(float $amount) {
  if ($amount > 5000) {
    throw new PaymentFailedException("Charge declined");
  }
}

Why custom exceptions help

They let you catch specific problems differently.

try {
  chargeCard(7000);
} catch (PaymentFailedException $e) {
  echo "Payment issue: " . $e->getMessage();
}
