var_dump - Dumps information about a variable
Manual
Code Examples

var_dump( mixed$value, ... mixed$values ): void

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.

All public, private and protected properties of objects will be returned in the output unless the object implements a __debugInfo() method.

As 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).

Parameters

value

The expression to dump.

values

Further expressions to dump.

Return Values

No value is returned.
