Synopsis
mixed print_r(mixedvalue[, boolreturn])
Outputs value in a human-readable
manner. If value is a string, integer, or
float, the value itself is output; if it is an array, the keys and
elements are shown; and if it is an object, the keys and values for
the object are displayed. This function returns true. If return
is set to true, then the output is
returned rather than displayed.
