Php mysql result () function

Write your php code

 
<?php ?>

Php Result


Your code below



(PHP 3, PHP 4 , PHP 5)

mysql_result -- Get result data

Syntax

mixed mysql_result ( resource result, int row [, mixed field] )

Retrieves the contents of one cell from a MySQL 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 MySQL result set on success, or 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());
}
$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);
?>

Notes

Note: Calls to mysql_result() should not be mixed with calls to other functions that deal with the result set.
