mysql_result — Get result data
Această extensie este dezaprobată începând cu PHP 5.5.0 și va fi eliminată în viitor. În locul ei trebuie utilizate extensiile MySQLi sau PDO_MySQL. Vedeți de asemenea ghidul MySQL: selectarea unei API și FAQ asociat pentru mai multe informații. Alternative ale acestei funcții includ:
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.
result
Rezultatul de tip resource, care este evaluat. Acest rezultat provine de la apelul funcției mysql_query ().
rowThe row number from the result that's being retrieved. Row numbers start at 0.
fieldThe 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.
The contents of one cell from a MySQL result set on success, or
FALSE on failure.
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($result, 2); // outputs third employee's name
mysql_close($link);
?>
Notă:
Calls to mysql_result() should not be mixed with calls to other functions that deal with the result set.
