mysql_result
Synopsis
mixed mysql_result(result handle, row_offset[, field]);
mysql result result handle:
Result handle returned by mysql_db_query() or mysql_query()
int row_offset: Row offset
to use
mixed field (optional):
Field offset or field name to use
Description
mysql_result() fetches a single field from a MySQL result set. The function accepts two or three arguments.
The first argument should be a mysql result handle returned by mysql_db_query() or mysql_query() .
The second argument should be the row from which to fetch the field, specified as an offset. Row offsets start at 0.
The optional last argument can contain a field offset or a field name. If the argument is not set, a field offset of 0 is assumed. Field offsets start at 0, while field names are based on an alias, a column name, or an expression. If an alias is present in the queryas name in the following query), the alias will be used as the field name. In other cases, either the column nameagein the following query) or expression birthday+0 in the following query) is used as the field name.
SELECT age, birthday+0, CONCAT(first, ' ', last) as name FROM table
Caution
Calls to mysql_result() reset the mysql result handle's internal row pointer.
This behavior means that calls to mysql_result() and mysql_fetch_array() , mysql_fetch_assoc() , mysql_fetch_row() , or mysql_fetch_object() should not be used on the same result handle.
Example
Example 827. Use mysql_result() to fetch a single value
<?php
// Included code that connects to a MySQL server and sets a default database
// See the MySQL Functions chapter introduction for the source code for the file
include ('mysql_connect.inc.php');
// Find out how many user logins are palindromes
$query = "SELECT count(login) FROM user WHERE login = reverse(login)";
echo 'Login Name Palindrome Count: ', mysql_result (mysql_query ($query), 0);
?>
Example 828. Use mysql_result() to fetch a couple of values
<?php
// Included code that connects to a MySQL server and sets a default database
// See the MySQL Functions chapter introduction for the source code for the file
include ('mysql_connect.inc.php');
// Get the current time and UNIX timestamp
$query = "SELECT NOW(), UNIX_TIMESTAMP() as stamp";
$mysql_result = mysql_query ($query)
or die ("Query '$query' failed with error message: \"" . mysql_error () . '"');
// Note how we use the function call for the first field name
// ...and the field alias for the second field name
echo 'The current date and time is: ', mysql_result ($mysql_result, 0, 'NOW()'), '.<br />',
'The current UNIX timestamp is: ', mysql_result ($mysql_result, 0, 'stamp'), '.<br />';
?>
