## 例

`

     void var_dump ( mixed $expression [, mixed $... ] )

`

## 説明

This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure. In PHP 5 all public, private and protected properties of objects will be returned in the output. TipAs with anything that outputs its result directly to the browser, the output-control functions can be used to capture the output of this function, and save it in a string (for example).

## 戻り値

No value is returned.
