Description:
------------
When I try to use __tostring to call a function I get an error that 'the function name must be a string'. While calling a class member with __tostring does work.
--Steven
Reproduce code:
---------------
<?php
class test {
public $string = 'Class member named `string`.';
public function __tostring() {
return 'string';
}
public function string() {
return "This is a string from a function.";
}
}
$test = new test();
$function_name = 'string';
print $test."\n";
print $test->$test."\n";
print $test->$function_name()."\n";
print $test->$test()."\n";
?>
Expected result:
----------------
---------- PHP ----------
string
Class member named `string`.
This is a string from a function.
This is a string from a function.
Output completed (0 sec consumed)
Actual result:
--------------
---------- PHP ----------
string
Class member named `string`.
This is a string from a function.
Fatal error: Method name must be a string in C:\projects\test.php on line 18
Output completed (0 sec consumed)
