The setHex method of PHP MapScript doesn't work

I'm using PHP MapScript 6.4 to interact with my Mapfile. I try to use the setHex() colorObj method like that:

$oStyle->color->setHex($color);

Where $color is an hexadecimal value as we can see in my logs

But regarding the MapScript https://mapserver.org/mapscript/php/phpmapscript.html#colorObj I can use setHex() method.

It works perfectly fine with $oStyle->color->setRGB(255,255,255); for example, so why not setHex()?

I'm using MapScript 6.4, I have looked at the 6.0.1 release documentation and the setHex() method exists.

thanks for using MapServer ! Here are some important points:

• setHex() is not available in MapServer 6.x for PHP MapScript: you can find the documentation for your exact version by:
  • going to https://mapserver.org
  • goto "Documentation" https://mapserver.org/documentation.html
  • at the top click on "Documentation for earlier versions of MapServer can be found on the Download page"
  • there you can see the various versions you can download for the documentation, such as 6.4 https://mapserver.org/pdf/MapServer-64.pdf
  • search for "setHex" and you will only find it only inside the SWIG MapScript section
• setHex() and toHex() for PHP MapScript were added to the MapServer 7.0.0 release (ticket: https://github.com/MapServer/MapServer/pull/5078)
• I've now added the text "new in version 7.0.0" to the colorObj for those methods at https://mapserver.org/mapscript/php/phpmapscript.html#colorobj

Please also note:

• there was a major vulnerability found in PHP MapScript recently (6.4.4 and 7.4.4 were released for this reason)
• PHP MapScript is unsupported/unmaintained, and therefore SWIG MapScript is recommended moving forward (which has full PHP7 support)

Thanks for using MapServer. Happy (fast) mapserving!
