如何将文件放入具有PHP函数的数组中？

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!

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;
}
