[SOLVED] CSV to Associative Array

CSV to Associative Array

I've seen numerous examples on how to take a CSV file and then create an associative array with the headers as the keys.

For example:

Brand,Model,Part,Test
Honda,Civic,123,244
Honda,Civic,135,434
Toyota,Supra,511,664

Where it would create an Array such as Array[$num][$key] where $key would be Brand, Model, Part, Test.

So If I wanted to access the test value "434" I would have to loop every index in the array and then ignore any Brands that were not honda, and any models that were not Civic

What I need to do is access the value most directly, instead of running through a for loop going through each $num index. I want to be able to access the value test "434" with:

Array['Honda']['Civic']['135']

or control a for statement with looping through every model Honda has... something like

foreach $model in Array['Honda']

At the very least I need to be able to go through every model given a known Brand and access all the relative info for each.

Edit:

Just to confirm I was setting this up an example. My actually data has headers like:

brand model part price shipping description footnote

Of which I need to access all the information tied to the part (price, shipping,desc, footnote)

Solution

run over the csv file line by line, and insert to array like:

$array = $fields = array(); $i = 0;
$handle = @fopen("file.csv", "r");
if ($handle) {
    while (($row = fgetcsv($handle, 4096)) !== false) {
        if (empty($fields)) {
            $fields = $row;
            continue;
        }
        foreach ($row as $k=>$value) {
            $array[$i][$fields[$k]] = $value;
        }
        $i++;
    }
    if (!feof($handle)) {
        echo "Error: unexpected fgets() fail\n";
    }
    fclose($handle);
}
