How do I loop through this array?
Well I'm relatively new to the use of PHP arrays and I have the follow array I need to loop through this array 2280 and 2307 are the identifiers.
I'm find it hard trying to come up with a foreach() that collects all the data.
Array
(
[2280] => Array
(
[0] => http://deals.com.au//uploads/deal_image/2706.jpg
[1] => Yuan's Massage and Beauty
[2] => Get Hair Free in CBD! Only $99 for SIX MONTHS worth of the latest in IPL Permanent Hair Reduction. Choose which area you want treated! Valued at $900 from Yuan's Massage and Beauty in the Heart of Melbourne's CBD. Limited vouchers available

[4] => 900
[5] => 801
[6] => http://deals.com.au/1827
)
[2307] => Array
(
[0] => http://deals.com.au//uploads/deal_image/2683.jpg
[1] => Name Necklace Australia
[2] => Style yourself like SJP! Only $29 for a STERLING Silver Name Necklace plus get FREE delivery! Valued at $75 with NameNecklace.com.au
[3] => 29
[4] => 75

)
Your array snippet
$array = array( // foreach ($array as $k=>$subarray)
'2280' /* this is your $k */ =>
array( /* and this is your $subarray */
'http://deals.com.au//uploads/deal_image/2706.jpg',
And now you get data you need (you had to use nested foreach
since values of your array are arrays):
foreach ($array as $k=>$subarray) {
foreach ($subarray as $data) {
echo $data;//of subarray
}
}
UPDATE
The OPs comment quistion on my answer:
what if I wanted to be selective rather than get a massive data dump. if I echo $data how do I access specific rows?
Well, in most cases you should associate keys and data in your array (we call it associative array in PHP).
Example 1:
$hex_colors = array('FF0000', '00FF00' '0000FF');
Values are not assoiated with correspondent keys. PHP will assign 0,1,2... keys to arrays elements itself. In this case you would get green color's heximal value using auto-assigned by PHP
1 key: echo $hex_colors[1]; // 00FF00
and of course you should know it for sure. Usually this approach is used when you have strict data structure like array(red, green, bluee)
, but in most cases you better use the following approach:
Example 2:
$hex_colors = array('red'=>'FF0000', 'green'=>'00FF00' 'blue'=>'0000FF');
heximal colors representations are associated with appropriate keys echo $hex_colors['green']; // 00FF00
If your array was:
$array = array(
'2280' => array(
'image_url' => 'http://deals.com.au//uploads/deal_image/2706.jpg',
'product_name' => 'Yuan\'s Massage and Beauty',
'description' => 'Get Hair Free in CBD! Only $99 for SIX MONTHS worth of the latest in IPL Permanent Hair Reduction. Choose which area you want treated! Valued at $900 from Yuan's Massage and Beauty in the Heart of Melbourne's CBD. Limited vouchers available',
'price' => 99,
'weight_brutto' => 900,
'weight_netto' => 801,
'dealer_store' => 'http://deals.com.au/1827',
...
You would be able to access data using, let's call it "human-readable" keys:
foreach ($array as $id=>$product) {
echo '<a href="http://myshop.com/?product_id='.$id.'">Buy '.$product['name'].'</a>';
echo '<img class="product_thumbnail" src="'.$product['image_url'].'" />';
echo 'Description: '.$product['description'];
echo 'The price is '.number_format($product['price']);
...
}
It is well-suited for reading rows from database, for example:
while ($data = mysql_fetch_array($query_result_link, MYSQL_ASSOC)) {
// MYSQL_ASSOC flag is not necessary
// PHP will use this flag by default for mysql_fetch_array function
// keys of $data will be correspondent columns names returned by mysql query
echo $data['id'];
echo $data['title'];
...
}
Continue learning PHP
and you will find many more situations when it's more convenient to associate keys and values.
foreach ($arr1 as $key1 => $value1) {
//$key1==2280; $value1 is the array
foreach ($value1 as $key2 => $value2) {
//$key2==0;$value2="http://deals.com.au//uploads/deal_image/2706.jpg"
}
}
