Rewind the Iterator to the first element
Description
Iterator::rewind(): void
Rewinds back to the first element of the Iterator.
Note
This is the first method called when starting a Foreach loop. It will not be executed after Foreach loops.
As Foreach always calls this method before starting iteration, manually advancing the iterator position (for example via SplFileObject::seek) will be reset.
To iterate without rewinding the iterator, wrap it in a NoRewindIterator.
Parameters Parameters
Return Values
Any returned value is ignored.
