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 only public properties of objects will be returned in the output. var_export() and print_r() will also return protected and private properties.
Vink: Som med alt andet der udskriver data direkte til browseren, kan du bruge output-control funktioner til at fange data returneret af denne funktion, og gemme det i en streng (for eksempel).
See also var_export() and print_r().
