Sentenca:

foreach ($this->table as $alias => &$tableObject) {
    $tableObject = clone $tableObject;
}

What is the meaning of & before the variable $tableObject? I have seen some codes that have & before any var only one character and not 2 as AND(&&) always before some variable? Can someone explain me, or at least tell me the name so I can do a better search.

Thank you.

  • OK, I thought, thanks for the guidance.

  • If those contents don’t resolve, explain to me here the question that I help.

  • Thanks, but this well explained and still has other reference links in the answers. Vlw.
