Synopsis
int count(mixedvalue[, intmode])
Returns the number of elements in the value; for arrays or
objects, this is the number of elements; for any other value, this is
1. If the parameter is a variable
and the variable is not set, 0 is
returned. If mode is set and is COUNT_RECURSIVE, the number of elements is
counted recursively, counting the number of values in arrays inside
arrays.
