I saw the line below in a class method :
return $return === 1;
What's the meaning of this ? As "===" is a comparaison operator, what would be the expected behavior of using this operator directly in a return ? Return only if 1 ?
Thanks

can you please help i just want to know why we use #in_array function.
$name = array("ravi", "ram", "rani", 87);
if (in_array("ravi", $name, TRUE)){
}
if (#in_array("ravi", $name, TRUE)){
}
The "#" symbol turn off the errors. It is not a good idea to use it.
