Method details

addCondition()

protected function addCondition(string $attribute, bool $partial = false): void

Registers an exact, partial, or leading numeric comparison condition.

Parameters

Parameter	Type	Description
`$attribute`	`string`	Attribute supplying the filter value and naming the row key to compare.
`$partial`	`bool`	Whether to match the value as a substring instead of requiring equality.

addMinimumCondition()

protected function addMinimumCondition(string $attribute, float $value): void

Registers a numeric greater-than-or-equal condition.

Parameters

Parameter	Type	Description
`$attribute`	`string`	Attribute naming the row key to compare.
`$value`	`float`	Inclusive lower bound the row value must reach.

filter()

protected function filter(array<int, yii\debug\models\search\TRow> $rows): list<yii\debug\models\search\TRow>

Applies all registered conditions.

Parameters

Parameter	Type	Description
`$rows`	`array<int, yii\debug\models\search\TRow>`	Rows to filter; typed row objects or string-keyed arrays.

Returns

list<yii\debug\models\search\TRow>: Rows matching every registered condition, reindexed.
