These mysql_* functions are deprecated and other functions are available that gives better security and functionality.
Note: As an alternative, use either _assoc or _row though.
The function returns an associative array of strings that corresponds to the fetched row, or FALSE if there are no more rows. The associativity array tells us about the key value pair, whereas the key tells about any column name and the value tells about the row value.
Here we can map the column name as key and value as row. For example.
Key is ID and value is corresponding name.
This function name suggests that it returns an array. It fetches a result row as an associative array, a numeric array, or both. It has both numeric values as well as string values for a key.
This function returns row as an object and does not return an array.
