PHP yana sarrafa kuskure tare da exceptions da aka kama ta try/catch/finally. Sarrafa exception sosai nufin kama nau'ikan takaici, samar da custom exceptions masu ma'ana, tsaftace albarkatun, kuma kada kasantsa bayani na ciki ga masu amfani.

Kama takaici nau'ikan exception (mafi takaici na farko), yi amfani da Throwable a matsayin ƙarshen kama duka (ya ƙunshi Error da Exception), kuma yi amfani da finally don tsaftace abubuwa da dole ne su aiwu koyaushe.
// throwing
if ($amount < 0) {
throw new InvalidArgumentException("Amount must be positive, got $amount");
}
// a custom exception for your domain
class InsufficientFundsException extends Exception {
public function __construct(private float $shortfall) {
parent::__construct("Short by $shortfall");
}
public function getShortfall(): float { return $this->shortfall; }
}
throw new InsufficientFundsException(50.0);
Nau'ikan custom exception classes suna sa sarrafa kuskure ta bayyani kuma suna ba da damar masu kira ka kama kuskuren yanki takaici.
try {
$db->query(...);
} catch (PDOException $e) {
// wrap with context, preserving the original as the "previous" exception
throw new RepositoryException("Failed to load user", 0, $e);
}
Third constructor argument yana jigon original exception ($e->getPrevious()), adana cikakken dalili don debugging.
✓ Catch SPECIFIC exceptions, not a blanket Throwable (unless intentionally last)
✓ Don't swallow exceptions silently (empty catch) — log or re-throw
✓ Use finally / proper cleanup for resources (files, connections)
✓ Create meaningful custom exceptions for domain errors
✓ SECURITY: log details internally; show users a generic message (don't leak
stack traces / internal info — display_errors off in production)
Sarrafa exception sosai mai mahimmanci ne don gina applicationsn PHP masu karfi, aboɓi, kuma aminci.
Janye try/catch/finally tsarin, kama takaici nau'ikan exception (don manipula takaici) tare da Throwable a matsayin ƙarshen kama duka (da ke ɓoyewa Error da Exception a halin yau), kuma yi amfani da finally don garantiwar tsaftace, shi ne mahimmin ilimi na kullun.
//Bayan aiki, masu kyau suna matuƙa: samar da meaningful custom exceptions don kuskuren yanki suna sa code bayyani kuma suna ba da damar masu kira ka sarrafa gazawan takaici; exception chaining yana adana tushen dalili don debugging; kuma mai mahimmanci, ba ka inyar exception a shiru (logging ko jefa sake maimakon haka) yana hana batutuwan damuwa.
Albarka musamman mahimmanci shi ne aminci: exceptions da kuskuren ba ya kamata kasantsu masu amfani (stack traces da bayani na ciki suna bugi mahimman ba da amsa kuma suna taimakawa maharin — don haka display_errors a kasa a aikin production).
Sanin sarrafa exceptions sosai — kama takaici, custom exceptions, tsaftace, jigon, kuma aminci logging maimakon kasantsu — yana banbanta karfin, professional PHP daga code marasa ikon da ke zuguje da waje ko ke bugi ba da amsa, gida ya zama mahimmin ilimi don gina aboɓi masu karfi, aminci.
