Using a PHP class constant for a key in a YAML hash as a method argument produces a ParseException #36624
Description
Symfony version(s) affected: 4.4.7
Description
Virtually the same as #35179 but with different exceptions.
When trying to use a PHP class constant as a YAML key for a hash (as a method argument), I receive one of the following.
- a
\Symfony\Component\Yaml\Exception\ParseExceptionwith the messageThe constant "\VENDOR\PRODUCT\Example" is not defined at line 7 (near "!php/const \VENDOR\PRODUCT\Example").if I use YAML Variant A below. - a
\Symfony\Component\Yaml\Exception\ParseExceptionwith the messageMalformed inline YAML string: ""\VENDOR\PRODUCT\Example" at line 7 (near ""\VENDOR\PRODUCT\Example").if I use YAML Variant B below. I observe the same behavior when using single quotes.
How to reproduce
Using the following class and Symfony YAML DI files produces the above.
<?php
declare(strict_types=1);
namespace VENDOR\PRODUCT;
class Example
{
public const CONSTANT_1 = 'constant_1';
public const CONSTANT_2 = 'constant_2';
private $Options;
public function addOptions(array $options): Example
{
$this->Options[] = $options;
return $this;
}
}# YAML Variant A
services:
VENDOR\PRODUCT\Example:
class: VENDOR\PRODUCT\Example
public: false # probably unrelated
shared: true # probably unrelated
calls:
- [addOptions, [{
!php/const \VENDOR\PRODUCT\Example::CONSTANT_1: 'value_0',
key_1: "value_1",
key_2: "value_2"
}]]# YAML Variant B
services:
VENDOR\PRODUCT\Example:
class: VENDOR\PRODUCT\Example
public: false # probably unrelated
shared: true # probably unrelated
calls:
- [addOptions, [{
!php/const "\VENDOR\PRODUCT\Example::CONSTANT_1": 'value_0',
key_1: "value_1",
key_2: "value_2"
}]]Also, the control case and global PHP constants (in both variants) work as expected, i.e:
# YAML Variant A
services:
VENDOR\PRODUCT\Example:
class: VENDOR\PRODUCT\Example
public: false # probably unrelated
shared: true # probably unrelated
calls:
- [addOptions, [{
!php/const PHP_INT_MAX: "value_0",
key_1: "value_1",
key_2: "value_2"
}]]# YAML Variant B
services:
VENDOR\PRODUCT\Example:
class: VENDOR\PRODUCT\Example
public: false # probably unrelated
shared: true # probably unrelated
calls:
- [addOptions, [{
!php/const "PHP_INT_MAX": "value_0",
key_1: "value_1",
key_2: "value_2"
}]]
