Bug description: References passed to closures as variables corrupt original
passed variable
Description:
------------
See the reproduce code. I have a variable $ref, which is a reference to
another variable. I am passing $ref to closure as use() by value, but, this
kind of passing corrupts $ref variable after definition of closure and $ref
becomes no longer reference, but points directly to copied data of $source
variable, which $ref was previously referring to. However, if i define
closure the following way:
$closure =function() use( &$ref) {// note pass-by-reference
echo $ref;
};
the $ref does not loose it's state.
Reproduce code:
---------------
$source ='Dmitry';
$ref =&$source;
$closure =function() use( $ref) {
echo $ref;
};
$ref ='Dmitry2';
echo $ref ."\n";
echo $source ."\n";
Expected result:
----------------
Dmitry2
Dmitry2
Actual result:
--------------
Dmitry2
Dmitry
