php - After array_filter(), how can I reset the keys to go in numerical order starting at 0

Question

I just used array_filter to remove entries that had only the value '' from an array, and now I want to apply certain transformations on it depending on the placeholder starting from 0, but unfortunately it still retains the original index. I looked for a while and couldn't see anything, perhaps I just missed the obvious, but my question is...

How can I easily reset the indexes of the array to begin at 0 and go in order in the NEW array, rather than have it retain old indexes?

Answer 1

If you call array_values on your array, it will be reindexed from zero.
