Bug description:var_export unnecessarily refers to classes in a namespace
sensitive way
Description:
------------
I use var export to generate PHP code fragments as one of it's strength is
that it's output is an expression of parseable PHP. However, when
var_export refers to classes, it refers to their relative name (from root)
instead of their absolute name, making you unable to use the output in
namespace context (contexts with a specified namespace).
Too illustrate this problem, say we're exporting an instance of the class
'foo\bar\BazClass'. var_export will now return something like:
"foo\bar\BazClass::__set_state(...)"
If inserted into a file with a beginning declaration "namespace foo_space"
this code will not work as the class in the expression would refer to
foo_space\foo\bar\BazClass which is incorrect and probably throws a fatal
error.
A simple fix is to make the ouput of var_export return namespaced classes
with an initial '\' e.g. instead of the above, make it return:
"\foo\bar\BazClass::__set_state(...)"
This would make the expression work in any namespace context.
Test script:
---------------
<?php namespace foo\bar;
class BazClass {
public $x = 3.14;
public $y = 5.14;
}
$baz = new BazClass();
$baz->x = 4.14;
$baz->y = 5.14;
$file = tempnam(sys_get_temp_dir(), "tst");
file_put_contents($file, '<?php namespace foo_space; return ' .
var_export($baz, true) . ";");
$class = require($file);
echo $class->x + $class->y;
Expected result:
----------------
9.28
Actual result:
--------------
Fatal error: Class 'foo_space\foo\bar\BazClass' not found in
C:\Windows\Temp\tst88FE.tmp on line 1
