Error when I try to put an array out into html

The following code is an associated array which takes info form a search engine such as url,title and snippet,

$googleArray = array(); 

    $find = array ('http://','https://','www.');                    
    $score = 100;                  



foreach ($all_items as $item)  // 
{   
    $googleArray[str_replace ($find, '', ($item->{'link'}))] = array(         
    'title'=> $item->{'title'},
    'snippet' => $item->{'snippet'},
    'score' => $score--
     );

}

I know want to print this out in html on a webpage, I've tried this code.

foreach ($all_items as $item)
{   
    echo "<href={$googleArray[($item->{'link'})]}>". $googleArray['title'] . "</a> <br>" .        
    $googleArray['link'] . "<br>" . $googleArray['snippet'];
    echo "<br>"; echo "<br>";

}

These are the errors I'm getting

Notice: Undefined index: http://www.time.com/ 

Notice: Undefined index: title 

Notice: Undefined index: link 

Notice: Undefined index: snippet

Can anyone see where I'm going wrong

It was as simple has this in the end

foreach($all_items as $item){
        echo  "<a href=\"{$item->link}\">{$item->title}</a><p>{$item->snippet}</p>". "<br>";

    }

and it only took me a full day to figure it out, lol

To read from the array, you are using the link property of an item as a key:

echo "<href={$googleArray[($item->{'link'})]}>

But earlier in the code, you are not using that exact link to write the value. You write using

$googleArray[str_replace ($find, '', ($item->{'link'}))];

so you are not using $item->{'link'}, but a modified version (with str_replace) of that link.

So that is one issue.

The other issue, is that title and snippet are keys in an array that is a value of a key in $googleArray, so to get those values, you should read $googleArray[$key]['snippet'] instead of $googleArray['snippet']. $key in this case being the corrected key after you fixed the first problem. ;)
