i am able to fetch the result individually like this
$finalid = $array['product']['id'];
echo $finalid;
but wish to fetch each and every data even the inner most values using for loop. for this i tried this
$c=count($result);
for ( $i=0; $i < $c; $i++)
{
echo $array[$i]['id'];
echo $array[$i]['images'][0];
echo $array[$i]['options'][0]['product_option_id'];
echo $array[$i]['images'][0]['option_value'][0]['product_option_value_id'];
echo $array[$i]['images'][0]['option_value'][1]['product_option_value_id'];
}
but it didn't displayed any result can anyone tell how it can be done

Answer 1

Use:
$products = $result['product'];
foreach ( $products as $product )
{
echo $product['id'];
echo $product['images'][0];
echo $product['options'][0]['product_option_id'];
echo $product['images'][0]['option_value'][0]['product_option_value_id'];
echo $product['images'][0]['option_value'][1]['product_option_value_id'];
}

Answer 2

You may want a recursive function like this to print your multidimensional arrays:
function printIt($data){
if (is_array($data)){
foreach ($data as $index=>$slice){
if (is_array($slice)){
printIt($slice);
}else{
echo $index.": ".$slice."<br>";
}
}
}else{
echo $data."<br>";
}
}
printIt($yourArray);

Answer 3

Use foreach instead,
foreach ( $array['product'] as $product)
{
echo $product['id'];
echo $product['images'][0];
echo $product['options'][0]['product_option_id'];
echo $product['options'][0]['option_value'][0]['product_option_value_id'];
echo $product['options'][0]['option_value'][1]['product_option_value_id'];
}
Here you will be looping inside each element of $array['product'] and for each loop $product will have the current element of $array['product'].
The mistake in your attempt was in [$i]. For each loop $i would have 0,1,2 etc and the array index would be $array['product'][0],etc but there is no element of that sort. Your method works if your array is an Indexed array, but here it is an Associative Array.

Try this,
<?php
foreach($result as $res){
echo '<pre>'; echo $res['id'];
if(is_array($res['options']) && !empty($res['options'])) {
foreach($res['options'] as $option) {
echo '<pre>'; echo ($option['product_option_id']);
if(is_array($option['option_value']) && !empty($option['option_value'])) {
foreach($option['option_value'] as $option_value) {
echo '<pre>'; echo $option_value['product_option_value_id'];
}
}
}
}
?>
