Question

I found this piece of code in the Phoronix Test Suite:

$os_packages_to_install = explode(' ', implode(' ', $os_packages_to_install));

I’ve seen it before and I don’t see it’s point. What does it do?

Answer 1

It will return an array but the difference with $os_packages_to_install is that if a value of $os_packages_to_install contains a space, it will also be splitted.

so:

["hjk jklj","jmmj","hl mh","hlm"]

implode gives:

"hjk jklj jmmj hl mh hlm

explode again will give:

["hjk","jklj","jmmj","hl","mh","hlm"]
