Question

index.blade.php中的代码输出为：

Array
(
    [0] => <strong>Wheat</strong> Flour
    [1] => Tomato Purée
    [2] => Mozzarella Cheese (<strong>Milk</strong>) (16%), Pepperoni (10%), Water, Mini Pepperoni (3.5%), Yeast, Dextrose, Rapeseed Oil, Salt, Sugar, Dried Garlic, Dried Herbs, Spice. Pepperoni contains: Pork, Pork Fat, Salt, Dextrose, Spices, Spice Extracts, Antioxidants (Extracts of Rosemary, Sodium Ascorbate), Preservative (Sodium Nitrite). Mini Pepperoni contains: Pork, Pork Fat, Salt, Dextrose, Spices, Spice Extracts, Sugar, Antioxidants (Sodium Erythorbate, Extracts of Rosemary), Preservative (Sodium Nitrite).
)

与[0]和[1]不同，[2]有许多成分。我需要能够将它们全部分开到自己的行（使用逗号和空格等作为断点）。我在JavaScript中实现了这一点：.split(/[:;,.<> /)(]+/);

这里显示的结果将是一个很好的例子： and here is a picture of what it looks like但是在尝试模拟这个时，我得到一个数组到字符串转换错误。

index.blade.php

require_once 'HTTP/Request2.php';

$request = new Http_Request2('https://dev.tescolabs.com/product/');
$url = $request->getUrl();

$headers = array(
    // Request headers
    'Ocp-Apim-Subscription-Key' => 'key',
);

$request->setHeader($headers);

$parameters = array(
    // Request parameters
    'gtin' => '05054402006097',
);

$url->setQueryVariables($parameters);

$request->setMethod(HTTP_Request2::METHOD_GET);

// Request body
$request->setBody("{body}");

try
{
    $response = $request->send();
    $result = $response->getBody();

    //true decodes the json into an associative array instead of stdObject
    $decoded = json_decode($result,true);

    $ingredients = $decoded['products'][0]['ingredients'];
    print_r($ingredients);

}
catch (HttpException $ex)
{
    echo $ex;
}

Answer 1

//true decodes the json into an associative array instead of stdObject
$decoded = json_decode($result,true);

// can now target ingredient array
$ingredients = $decoded['products'][0]['ingredients'];

//turn contents into string so can use preg_split(
 $test = implode($ingredients);

$ingredientList = preg_split("/[\s, ]+/", $test);
print_r($ingredientList);

Answer 2

我在JavaScript中实现了这一点：.split(/[:;,.<> /)(]+/);

PHP中的等效代码使用preg_split()：

 $pieces = preg_split('@[:;,.<> /)(]+@', $ingredients[2]);
