(pg. 123)
The function has the following correct syntax:
mysql_result(resource, row[, column])
However, in the explanation paragraph, 2nd sentence, it uses the term field erroneously instead of the term column. It should read as follows:
If column is specified instead of the value of the
first column, the specified column is retrieved (can be referenced by number
starting with 0 or by name/alias).
It’s the little things, like changing the term used to be clearer to the reader and forgetting to update everything.
