What does result mean in php

The mysql_result () function returns the value of a field in the result set.

If successful, the function returns the field value. If it fails, false is returned.

Grammar

Mysql_result (data,row,field)

Parameter description

Data is required. Specifies the result identifier to be used. This identifier is returned by the mysql_query () function.

Row is required. The required line number. The line number starts at 0.

Field is optional. Specifies which field to get. It can be a field offset value, a field name, or table.fieldname.

If the parameter is not specified, the function gets the first field from the specified row.

Description

When used for a large result set, you should consider using a function that can get the entire row. These functions return the contents of multiple units in a single function call, much faster than mysql_result ().

Also note that it is much faster to specify a numeric offset in a field parameter than to specify a field name or tablename.fieldname.
