小编ari*_*iel的帖子

当我做var_dump($ punkty); 我有这样的事情:

array(1) 
{ 
[0]=> array(4) 
    { 
    ["id"]=> string(2) "28" 
    ["mapa"]=> string(97) "a:3s:3:"lat";s:17:"49.21103723075132";s:3:"lng";s:18:"22.330280542373657";s:4:"zoom";s:2:"17";}" 
    ["miasto"]=> string(5) "Cisna" 
    ["nazwa_obiektu"]=> string(44) "Cisna - noclegi u Miros?awy w Bieszczadach" 
    }
} 

当我做:

foreach ($punkty['mapa'] as $item)
        {
        echo $item;
        }

我明白了

Invalid argument supplied for foreach() 

怎么解决？

我的数组有问题,这是我的代码:

$random_string = array();
for($i=0;$i<10;$i++)
{
$zmienna = generatePassword();
//echo $zmienna;
if (in_array($zmienna, $random_string))
$random_string[$i] = $zmienna;
}

var_dump($random_string);

在屏幕上我看到了olny

array(0) { } 

怎么了？Becouse我确信它generatePassword();运作良好

当我这样做时,print_r($nodes);我得到:

Array (
  [0] => SimpleXMLElement Object (
    [kategoria_6] => 1
    [opis_6] => 1
    [img] => slides/slide0.jpg
  )
  [1] => SimpleXMLElement Object (
    [kategoria_6] => 2
    [opis_6] => 2
    [img] => slides/slide1.jpg
  )
  [2] => SimpleXMLElement Object (
    [kategoria_6] => 3
    [opis_6] => 3
    [img] => slides/slide4.jpg
  )
  [3] => SimpleXMLElement Object (
    [kategoria_6] => 4
    [opis_6] => 4
    [img] => slides/slide3.jpg
  )
  [4] => SimpleXMLElement Object (
    [kategoria_6] => 7
    [opis_6] => 7
    [img] => slides/slide2.jpg
  ) …
