adding values in a 2d associative array - php

Question

The following code returns an associated array with a url,title and snippet from a search engine and it works fine
$js = json_decode($data);
$blekkoArray = array();
$find = array ('http://','https://','www.');
foreach ($js->RESULT as $item)
{
$blekkoArray[$i]['url'] = str_replace ($find, '', ($item->{'url'}) );
$blekkoArray[$i]['title'] = ($item->{'url_title'});
$blekkoArray[$i]['snippet'] = ($item->{'snippet'});
$i++;
}
print_r ($blekkoArray);
I'm trying to add another value to the array so that I can score each element, eg. I want the first result to have a score of 100, the second 99, the third 98 and so on, the following code spits out the same as the above. Therefore I can't seem to add 'score' the the array, any thoughts.
Reagrds
$js = json_decode($data);
$blekkoArray = array();
$find = array ('http://','https://','www.');
foreach ($js->RESULT as $item)
{
$score = 100;
$blekkoArray[$i]['url'] = str_replace ($find, '', ($item->{'url'}) );
$blekkoArray[$i]['title'] = ($item->{'url_title'});
$blekkoArray[$i]['snippet'] = ($item->{'snippet'});
$blekkoArray[$i]['score'];
$i++;
$score--;
}
print_r ($blekkoArray);

Answer 1

You have done 2 mistakes.
1) you have initialized $score inside foreach loop, it should be outside otherwise you will get $score = 100 always.
2) You are not assigning the $score in array,
$score = 100; // move the initialization of $score outside of loop
foreach ($js->RESULT as $item)
{
$blekkoArray[$i]['url'] = str_replace ($find, '', ($item->{'url'}) );
$blekkoArray[$i]['title'] = ($item->{'url_title'});
$blekkoArray[$i]['snippet'] = ($item->{'snippet'});
$blekkoArray[$i]['score'] = $score; // assign the $score value here
$i++;
$score--;
}
OR suggested by u_mulder
$blekkoArray[$i]['score'] = $score--;

Answer 2

Bring the $score = 100; outside of the foreach array. You're resetting it to 100 each loop.
And use
$blekkoArray[$i]['score'] = $score--;
or the same on two lines:
$blekkoArray[$i]['score'] = $score;
$score--;
And next to that, can't you use the key in the foreach? Like this? This is just a guess, as I don't know what $i is. It's not defined or initialised in your code, so...
And a little bonus modification: if you're not using variables as fieldnames, the $var->{'fieldname'} notation can be simplified to $var->fieldname.
All together, this is giving the following code:
$score = 100;
foreach ($js->RESULT as $i => $item)
{
$blekkoArray[$i]['url'] = str_replace ($find, '', $item->url);
$blekkoArray[$i]['title'] = $item->url_title;
$blekkoArray[$i]['snippet'] = $item->snippet;
$blekkoArray[$i]['score'] = $score--;
}
