Definition and Usage

This function returns the field value on success, or FALSE on failure.
Syntax
mysql_result(data,row,field)
| Parameter | Description |
|---|---|
| data | Required. Specifies which result handle to use. The data pointer is the return from the mysql_query() function |
| row | Required. Specifies which row number to get. Row numbers start at 0 |
| field | Optional. Specifies which field to get. Can be field offset, field name or table.fieldname. If this parameter is not defined mysql_result() gets the first field from the specified row |

Example
<?php
$con = mysql_connect("localhost", "peter", "abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("test_db", $con);
$sql = "SELECT * from Person";
$result = mysql_query($sql,$con);
echo mysql_result($result,0);
mysql_close($con);
?>
$con = mysql_connect("localhost", "peter", "abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("test_db", $con);
