No description

addCasters(array $casters)

Adds casters for resources and objects.

setMaxItems(int $maxItems)

Sets the maximum number of items to clone past the minimum depth in nested structures.

setMaxString(int $maxString)

Sets the maximum cloned length for strings.

setMinDepth(int $minDepth)

Sets the minimum tree depth where we are guaranteed to clone all the items. After this depth is reached, only setMaxItems items will be cloned.

Data
cloneVar(mixed $var, int $filter = 0)

Clones a PHP variable.

array
doClone(mixed $var)

Effectively clones the PHP variable.

array
castObject(Stub $stub, bool $isNested)

Casts an object to an array representation.

array
