DuplicateException extends DataException
in package

Exception for database constraint violations (e.g., unique, foreign key).

Thrown for duplicate key or similar constraint violations. Returns HTTP 400 (bad request) instead of 500 since it's typically a client input issue.

Methods

__construct()

Initialize a duplicate constraint exception.

public __construct([string|null $msg = null ][, int|null $code = null ][, Exception|null $parent = null ][, mixed $more = null ]) : mixed
Parameters
$msg : string|null = null

Error message. Defaults to 'duplicate'.

$code : int|null = null

HTTP status code. Defaults to 400.

$parent : Exception|null = null

Previous exception for chaining.

$more : mixed = null

throw()

Throw an exception with flexible named arguments.

public static throw([int|null $code = null ][, string|null $msg = null ][, Throwable|null $parent = null ][, mixed $more = null ]) : never

Static factory method for elegant exception creation. Only non-null arguments are included in the constructor call, allowing clean fluent syntax without positional confusion or needing to pass null for skipped parameters.

HTTP status code.

$msg : string|null = null

Error message.

$parent : Throwable|null = null

Previous exception for chaining.

$more : mixed = null

Structured error metadata.
