mysql_result
mysql_result
Get result data
Description
string mysql_result(resource result,
int row,
mixed field= =0);
Retrieves the contents of one cell from a MariaDB result set.
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 than mysql_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 to
mysql_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 MariaDB result set on success, or FALSE
on failure.
Examples

<?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($result, 2); // outputs third employee's name mysql_close($link); ?>

should not be mixed with calls to other functions that deal with the result set.
