PHP and Doxygen with multiple property declaration - php

Question

I finally got doxygen to work with php and PHPDoc styled comments (I'm removing '#package' with filter since it breaks up doxygen) though there's one thing I would love to have and are not able to figure out how.
In PHP I'm writing multiple property declaration in a class like this:
class Foo
{
private
/// the blue color
$blue,
/// the red color
$red,
/// the yellow color
$yellow;
public
/// the orange color
$orange,
/// black (no color)
$black;
public function bar() {}
}
If I'm now generating the docs, only the first property is shown as private Attribute while all other properties are simply referenced as Data Fields. So doxygen obviously doesn't parse the accesors of every property after the first one.
Is it possible to make this commentation style compatible to doxygen ?
P.S: I thought about applying a filter which converts it in doxygen-parsable code style. Though this would only be a fix I'm currently working on it.

Answer 1

I wrote this filter, that works for the example you provided. I think it should also work for more complex examples.
// Get the input
$source = file_get_contents($argv[1]);
$count = 0;
do {
$source = preg_replace('#(private|public|protected)(\s*[^$]*)(\$[^,;]+),#',
"$2 $1 $3;\n$1 ", $source, -1, $count);
} while($count > 0);
// Output
echo $source;
You can find this and other filters at my GitHub repository doxygen-php-filters.
