如何在 PHP 中将带有多个分隔符的 URL 字符串转换为另一个字符串？

发布于 2024-08-11 14:56:33 字数 726 浏览 2 评论 0原文

所以我有这个示例字符串：

?items=3744130|1^356221|2^356222|1

从 URL 中提取：

http://www.example.com/process.php?items=3744130|1^356221|2^356222|1

我需要将其转换为这个，但我一生都陷入困境。

?items=model_1=3744130&qty_1=1&model_2=356221&qty_2=2&model_3=356222&qty_3=1

我已经走到这一步了，但仅此而已。

$url = substr($_SERVER['QUERY_STRING'],6); 
$query = explode('^', $url); 
echo http_build_query($query, 'model_');

当前的输出是：

model_0=1234435%7C9&model_1=56788%7C9&model_2=6758765%7C9&model_3=3736543%7C9

如何将第一个集合设置为 model_1 而不是默认的 model_0？

谢谢

So I have this sample string:

?items=3744130|1^356221|2^356222|1

extracted from a URL:

http://www.example.com/process.php?items=3744130|1^356221|2^356222|1

I need to convert it into this, and for the life of me I'm getting stuck.

?items=model_1=3744130&qty_1=1&model_2=356221&qty_2=2&model_3=356222&qty_3=1

I've gotten this far but that's it.

$url = substr($_SERVER['QUERY_STRING'],6); 
$query = explode('^', $url); 
echo http_build_query($query, 'model_');

Output currently is:

model_0=1234435%7C9&model_1=56788%7C9&model_2=6758765%7C9&model_3=3736543%7C9

How can I get the first set to be model_1 instead of the default model_0?

Thanks

如果您希望编号从 1 开始，则需要先使用键构建数组，然后再将其传递给 http_build_query()。

$arr = array();
$count = 1;

foreach (explode('|', $_GET['items']) as $item) {
  $elements = explode('^', $item);
  if (count($elements) == 1) {
    $arr["model_$count"] = $elements[0];
    $arr["qty_$count"] = 1;
  }
  else {
    $arr["model_$count"] = $elements[1];
    $arr["qty_$count"] = $elements[0];
  }
  $count++;
}

$query = http_build_query($arr);

You need to build the array with keys before passing it to http_build_query() if you want the numbering to start with 1.

$arr = array();
$count = 1;

foreach (explode('|', $_GET['items']) as $item) {
  $elements = explode('^', $item);
  if (count($elements) == 1) {
    $arr["model_$count"] = $elements[0];
    $arr["qty_$count"] = 1;
  }
  else {
    $arr["model_$count"] = $elements[1];
    $arr["qty_$count"] = $elements[0];
  }
  $count++;
}

$query = http_build_query($arr);

快速补丁应该是

....
$url = substr($_SERVER['QUERY_STRING'],6);
$query = explode('^', $url);

array_unshift($query,'placeholder');
$result=http_build_query($query, 'model_');
$result = substr($result, 19);
....

A quick patch should be

....
$url = substr($_SERVER['QUERY_STRING'],6);
$query = explode('^', $url);

array_unshift($query,'placeholder');
$result=http_build_query($query, 'model_');
$result = substr($result, 19);
....

试试这个：

$items = explode('^', $_GET['items']);
$query = '';
foreach ($items as $key => $val) {
    list($model, $qty) = explode('|', $val);
    $query .= '&model_'.($key+1).'='.urlencode($model);
    $query .= '&qty_'.($key+1).'='.urlencode($qty);
}
echo substr($query, 1);

Try this:

$items = explode('^', $_GET['items']);
$query = '';
foreach ($items as $key => $val) {
    list($model, $qty) = explode('|', $val);
    $query .= '&model_'.($key+1).'='.urlencode($model);
    $query .= '&qty_'.($key+1).'='.urlencode($qty);
}
echo substr($query, 1);
