compact

 array compact ( mixed $varname [, mixed $... ] ) 

説明

Creates an array containing variables and their values. For each of these, compact() looks for a variable with that name in the current symbol table and adds it to the output array such that the variable name becomes the key and the contents of the variable become the value for that key. In short, it does the opposite of extract(). Any strings that are not set will simply be skipped.

戻り値

Returns the output array with all the variables added to it.
