Accessing and echoing an array within an array

[simonclay]

I would like to access each [price] in [prices] in the following array, to output a list and also show the lowest number.

 

I have tried a foreach loop and the min function but seem to be struggling to access the correct place in the array.

 

Here is the array (as a variable $prices)

Array ( 
	[0] => Array ( 
		[_id] => 20 
		[heading] => All Prices 
		[prices] => Array ( 
			[0] => Array ( 
				[price] => 4.99
			) 
			[1] => Array ( 
				[price] => 9.50 
			) 
			[2] => Array ( 
				[price] => .99 
			)
			[3] => Array ( 
				[price] => 6.75 
			)
			[4] => Array ( 
				[price] => 12.97 
			) 
		) 
	[_page] => /region-tests/index.php 
	[_pageID] => 15 
	[_sortvalue] => 1000
    )
) 

foreach ($prices['price'] as $price) {
  echo "<li>" . $price . "</li>";
}
			  
echo "The lowest price is: " . min($result[0]['prices']);

But my php above is not outputting a list of prices or the lowest price.

 

I get the following errors:

 

For the foreach line:

Notice: Undefined index: price

Warning: Invalid argument supplied for foreach()

 

And the min line:

Notice: Array to string conversion

Look at the structure:

Array ( 
	[0] => Array ( 
		[prices] => Array ( 

$prices is an array (first line) which contains a [0] key (second line) which is itself an array that contains a [prices] key (third line).

 

foreach ($prices[0]["prices"] as $price) {

Each $price looks the same as the first one, which is

			[0] => Array ( 
				[price] => 4.99
			) 

an array that contains a [price] key.

echo "<li>" . $price["price"] . "</li>";

Thanks very much for your reply. 

 

I get the following output with that code.

<b>Notice</b>:  Undefined variable: result in <b>/region-tests/index.php</b> on line <b>49</b><br />
<br />
<b>Warning</b>:  Invalid argument supplied for foreach() in <b>/region-tests/index.php</b> on line <b>52</b><br />
<br />
<b>Notice</b>:  Undefined variable: price in <b>/region-tests/index.php</b> on line <b>58</b><br />
<li></li>

That would have to do with code that you haven't posted.
