mysql_result
(PHP 4, PHP 5)
mysql_result — Get result data
Description
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker thanmysql_result(). Also, note that specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Parameters
result
The result resource that is being evaluated. This result comes from a call tomysql_query().
row
The row number from the result that's being retrieved. Row numbers start at 0.
field
The name or offset of the field being retrieved.
It can be the field's offset, the field's name, or the field's table dot field name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name. If undefined, the first field is retrieved.
Return Values
The contents of one cell from a MySQL result set on success, or [false](reserved.constants.php#constant.false) on failure.
Examples
Example #1 mysql_result() example
<?php $link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); if (!$link) { die('Could not connect: ' . mysql_error()); } if (!mysql_select_db('database_name')) { die('Could not select database: ' . mysql_error()); } $result = mysql_query('SELECT name FROM work.employee'); if (!$result) { die('Could not query:' . mysql_error()); } echo mysql_result($result, 2); // outputs third employee's namemysql_close($link); ?>
Notes
Note:
Calls to mysql_result() should not be mixed with calls to other functions that deal with the result set.

`here's a rough replacement using mysqli:
if (!function_exists('mysql_result')) {
function mysql_result($result, number,number, number,field=0) {
mysqli_data_seek($result, $number);
row=mysqlifetcharray(row = mysqli_fetch_array(row=mysqlifetcharray(result);
return row[row[row[field];
}
}
