有一个像这样的数组:
Array
(
[0] => stdClass Object
(
[url] => https://is0.Z0V.jpg
[width] => 370
[height] => 370
)
[1] => stdClass Object
(
[url] => https://is1.et/derived_pi0V_300x300.jpg
[width] => 300
[height] => 300
)
[2] => stdClass Object
(
[url] => https://is1.n100x100.jpg
[width] => 100
[height] => 100
)
[3] => stdClass Object
(
[url] => https://is1.t/dZ0V_36x36.jpg
[width] => 36
[height] => 36
)
)
我如何从这个foreach中获取[2]并将其插入到此:
foreach($fotoSuggSizes as $fotoSuggSize100)
{
$image_urlSugg100[] = array("urlx100"=>$fotoSuggSize100->url);
}

您可以使用array_splice
在exisitng数组中的特定偏移处插入另一个数组:
$insert = array("urlx100"=>$fotoSuggSize100->url);
array_splice($fotoSuggSizes, 2, 0, array($insert));
但是,如果您正在寻找的话,我不能完全确定您的问题。
另一种方式是:
$image_urlSugg100[] = array("urlx100" => $fotoSuggSizes[2]->url);

另一种方式是:
foreach($fotoSuggSizes as $n => $fotoSuggSize100)
{
if ($n != 2) continue;
$image_urlSugg100[] = array("urlx100"=>$fotoSuggSize100->url);
}

原始数组是否为$fotoSuggSize100
?
$image_urlSugg100[] = array("urlx100"=>$fotoSuggSize100[2]->url);
答案 3 :(得分:1)
也许我错过了这一点,但是:
$image_urlSugg100[] = array("urlx100"=>$fotoSuggSizes[2]->url);
或者,如果由于某种原因您特别想使用foreach()
方法:
foreach ($fotoSuggSizes as $k => $v)
{
if ($k == 2)
{
$image_urlSugg100[] = array("urlx100"=>$v->url);
}
}
