How can I get a file into an array with a PHP function?

Question

I have a text file called "product.txt" that includes some products:

Porsche Bike^A bike with a brand name!^10,000
Pretty Shoes^Come to our shoe store^54.45
Pie Fest!^Oh yeah this is officially the best pie ever^3.45
Inside Out Umbrella^Designer Umbrellas for low cost =^14.55
Coffee^Come get your morning dessert^4.59

I want to put them into an array with a function:

function loadFile() {
    $filename = ('product.txt');
    $file = fopen($filename, 'r');
    while (!feof($file)) {
        $line = trim(fgets($file));
        return $array = explode("^", $line);
    }
    fclose($file);
}

The problem with my function is that it won't put all of the products into the array, but only the first line!

You're returning inside the loop. That's why you only get the first line. — Don't Panic

I don't know if this applies to your particular solution but something like php.net/manual/en/function.fgetcsv.php might be better than coding it yourself. — kingsfoil

Change your function to

function loadFile() {
    $line = array();
    $filename = ('product.txt');
    $file = fopen($filename, 'r');
    while (!feof($file)) {
        $line[] = trim(fgets($file));
    }
    fclose($file);
    return $line;
}

It seems like the OP wants to create a multidimensional array, so I guess it should be: $line[] = explode("^", trim(fgets($file)));
