<?php
function get_info($name = 'friend', $title){ echo "Hi $name, are you a $title?"; }
get_info('','Developer');
?>
Why does this code doesnt work? What im trying to do here is only provide the value of the $title..

It seems that the way to make this work is to change the order of you variables. You should not set a default for the first argument, but for the second. More info can be found here, example #5.
Hope that helps, Cosmin

you have to provide the variable in the function. Why do you use a variable instead of text?
This code should work for you:
<?php
function get_info($title){
$name = 'friend';
echo "Hi $name, are you a $title?"; }
get_info('Developer');
?>

557 PointsHi Cosmin, so basically, you can only add default value to the last argument or add default value for both but not for the first argument only..
Illustration:
1: ($a, $b = 'default b value') = Correct
2 ($a = 'default a value', $b = 'default b value') = Correct
3 ($a = 'default a value', $b) = Incorrect
Is this correct?
