mysql_result

Get result data (PHP 4, PHP 5, PECL mysql:1.0)
string 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 1460. 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.

two simple but very useful functions, for converting a query to a value or an array: <?php function mysql_evaluate($query, $default_value="undefined") { $result = mysql_query($query); if (mysql_num_rows($result)==0) return $default_value; else return mysql_result($result,0); } function mysql_evaluate_array($query) { $result = mysql_query($query); $values = array(); for ($i=0; $i<mysql_num_rows($result); ++$i) array_push($values, mysql_result($result,$i)); return $values; } ?> http://tora.us.fm/_script/highlight.php?file=sql Usage examples: <?php $customer_count = mysql_evaluate("SELECT COUNT(*) FROM customers"); $customer_names = mysql_evaluate_array("SELECT name FROM customers"); $customer_type = mysql_evaluate("SELECT type FROM customers WHERE name='$name'", "DEFAULT_TYPE"); ?>

If you want to fetch the result from a mysql query similar to one of these two queries... $query = mysql_query("SELECT COUNT(*) FROM table"); $query = mysql_query("SELECT LAST_INSERT_ID()"); ... you would use mysql_result() like shown below to retrieve the output as an int. $result = mysql_result($query, 0, 0);

gack

if you want to do something based on the fact that the data is the same in the next row, then looking ahead is easy with this. <?php $i=0; $rows=mysql_num_rows($result); while($i < $rows) { $x = mysql_result($result, $i, 0); if ($x = mysql_result($result, $i+1, 0)) { echo "It's the same thing!"; } } ?>

<? $link = mysql_connect("host", "user", "passw"); mysql_select_db("database", $link); $number = 3; $insert = mysql_query("SELECT `test1`.*, `test2`.*, FROM `test1`, `test2`, ` WHERE ((`test1`.`author` = `test2`.`ID`) AND (`test2`.`ID` ='$number')) ORDER BY `toetsen`.`autoID` DESC",$link); echo mysql_result( $insert , 0, 'test1.question') ; #here he echoes the questions the stuff out of the first table echo mysql_result( $insert , 0, 'test2.name') ; #here he echoes the questions the stuff out of the second table ?>
