Appium experts , please help me with this

What are roadblocks , advantages, disadvantages one will encounter in setting appium with PHP from top to bottom like creating a POM framework, running test on both iOS and Android, Also if any of you experts have made any comparison between all languages ( for eg: Java you can achieve this but not using PHP etc ) I have setup appium using JAVA but client prefers to go with PHP since they have many resources who has PHP skills.
