Arrays are a crucial element of php. There are a number of array functions, look on php.net to see them. http://us2.php.net/manual/en/book.array.php
Data from databases is usually returned as an array, so given a table like this:
mysql> describe quotes; +--------+-----------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------+-----------------+------+-----+---------+----------------+ | id | int(7) unsigned | NO | PRI | NULL | auto_increment | | source | int(2) unsigned | YES | | NULL | | | quote | text | YES | | NULL | | | kw | varchar(50) | YES | | NULL | | +--------+-----------------+------+-----+---------+----------------+
and given the query, “select * from quotes limit 1” the mysql_fetch_assoc() function might return something like:
Array
(
[id] => 7
[source] => 1
[quote] => "Nothing more will be taken from you.' - Master Po
'But I have lost nothing.' - Young Caine
'But your innocence How shall that be returned?'" - Master Po
[kw] =>
)
That output is from the print_r() function, so if “$row” is the name of hte array, then you’d call print_r as print_r($row)
You can create an array a number of ways:
$arr = array(‘apple’, ‘orange’, ‘bananna’);
is pretty much the same as:
$arr = array();
$arr[] = ‘apple’;
$arr[] = ‘orange’;
$arr[] = ‘banana’;
