currently, i'm using eclipse neon , i'm thinking coding in php. usually, add appropriate plugins; 1 got me thinking on whether should install eclipse php developers instead. any thoughts on difference between installing php plugins vs. installing eclipse distro php? i prefer have eclipse installation tailored actual needs. therefore, if workspace holds php projects, i'd recommend using eclipse php developers package in case, ideally, wouldn't matter having many (unrelated) plug-ins within single installation. in reality, installing many plug-ins may increase time needed @ startup, because extensions of plug-ins need read increase likelihood of plug-ins not working together increase ui clutter caused contributions of many plug-ins
