我有一个像这样的数组
array
0 =>
array
'title' => string 'Last Name' (length=9)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 1
1 =>
array
'title' => string 'Title 1' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
2 =>
array
'title' => string 'Title 10' (length=7)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
3 =>
array
'title' => string 'Title 11' (length=7)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
4 =>
array
'title' => string 'Title 12' (length=7)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
5 =>
array
'title' => string 'Title 2' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
6 =>
array
'title' => string 'Title 3' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
7 =>
array
'title' => string 'Title 4' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
8 =>
array
'title' => string 'Title 5' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
9 =>
array
'title' => string 'Title 6' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
10 =>
array
'title' => string 'Title 7' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
11 =>
array
'title' => string 'Title 8' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
12 =>
array
'title' => string 'Title 9' (length=6)
'price' => string '0.0000' (length=6)
'price_type' => string 'fixed' (length=5)
'is_required' => int 0
所以问题是在阵列中我有头衔。当我做foreach循环时,标题显示为
LAST NAME:
Title 1:
Title 10:
Title 11:
Title 12:
Title 2:
Title 3:
Title 4:
Title 5:
Title 6:
Title 7:
Title 8:
Title 9:
正如您可以注意到,标题10在1之后显示,而且它的数字顺序不正确。我怎么能在PHP中解决这个问题。 感谢
受审 $ titles = array(); foreach($ product-> custom_options as $ key => $ row) { $ titles [$ key] = $ row ['title']; } var_dump(array_multisort($ titles,SORT_DESC,$ product-> custom_options));

usort($array, function($lhs, $rhs){
return strnatcmp($lhs['title'], $rhs['title']);
});

您永远不会对数组进行排序,因为您以这种方式插入项目,所以它按顺序显示,您首先需要按照字母数字的方式排序数组。尝试使用具有整数值的其他字段。

问题很可能是生成数组而不是现在修复它。从我看到你有一个标题作为第一个元素,从那时起你有没有正确“排序”的元素。
在不知道确切要求的情况下,根据您发布的内容,“排序”的方法是:
// $data array is the existing array
$new_array = array();
foreach ($data as $item) {
if ($item['title'] == 'Last Name') {
$new_array[0] = $item;
}
else
{
$key = intval(trim(str_replace("Title ", "", $item['title'])));
$new_array[$key] = $item;
}
}
ksort($new_array);
结果数组的元素键为0,标题为“标题XX”,其中XX为数字(取自标题元素
HTH
