Hello guys, I try to use 'ReflectionFunction' to retrieve the info of a function.
For example:
<?php
$rf = new ReflectionFunction('strstr');
echo $rf;
?>
=============== output ==================
Function [ <internal:standard> function strstr ] {
- Parameters [3] {
Parameter #0 [ <required> $haystack ]
Parameter #1 [ <required> $needle ]
Parameter #2 [ <optional> $part ]
}
}
The problem is there's no 'return type' (i.e. 'string' in this example)
info about the function.
Could you tell me how to retrieve the 'return type'?
Thanks.
