if statement within function call

[mwstewart]

Hi all,
I want to instantiate a class but only pass $var3 if it is actually set.

$result = $class->_method($var1, $var2, $var3);

What is the most efficient way to do this? Is there a way to do this check within the method call brackets?

i.e. something like:

$result = $class->_method($var1, $var2 (if(!empty($var3){"," . $var3}));

I obviously need to include the comma before $var3 if it isn't empty.

Thanks in advance!

if(isset($var3))
{
$result = $class->_method($var1, $var2, $var3);
}
else
{
$result = $class->_method($var1, $var2);
}

You could just pass it as null if it's empty:

$result = $class->_method($var1, $var2, (empty($var3)) ? null : $var3);

Remember that 0, "0", and "" will be considered "empty" by empty(), so if any of those might be valid values, then you'd probably want to use !isset() instead of empty().
