遍历foreach中的第一个项目两次

Question

I'm trying to figure out the cleanest way to loop through the first item in an array twice. My foreach looks like this:

foreach ($array as $arr) {
    $arr['item'];
}

The reason I'm asking is because I'm looping through and running a curl script that requires setting a cookie. On the first loop, it's not setting properly but it is on all others. Ideally I'd like to just hit that first twice, and overwrite the value I'm pulling.

Answer 1

If you need to make something twice with 1st element, you can make it this way

$firstItem = true;
foreach ($array as $arr) {
    if ($firstItem) {
       $arr['item'];
       $arr['item'];
       $firstItem = false;
    } else {
       $arr['item'];
    }
}

But instead of making it twice, maybe you should find out why it doesn't work first time? +1 to previous comment that you should fix a problem, but not workaround it.

If order is not important:

  array_push($array, reset($array));
  foreach ($array as $arr) {
      ...
  }

If it is, better use Elena's suggestion.
