I saw this code in some library

if (\count($this->variablesGlobal) > 0) {
    $this->variables = \array_merge($variables, $this->variablesGlobal);
    $variables = $this->variables;
} else {
    $this->variables = $variables;
}

and I wonder why is it has \ in php keywords.

I read the documentation about count, it simply state count and just used count in example without \

You don't need it, it is for classes when using namespace – JorgeeFG Dec 27 '19 at 16:37
``\`` is the namespace separator. – MC Emperor Dec 27 '19 at 16:38
