我有一个由竖线分隔的字符串组成的平面数组:
Array
(
[0] => style1|000000
[1] => style2|ff6600
)
我像这样迭代数据:
foreach ($styles as $key => $value) {
$sort_values[] = explode('|', $value);
}
print_r($sort_values)
显示:
Array
(
[0] => Array
(
[0] => style1
[1] => 000000
)
[1] => Array
(
[0] => style2
[1] => ff6600
)
)
我实际上想要一个具有关联第一级键的转置结构:
Array
(
[styles] => Array
(
[0] => style1
[1] => style2
)
[links] => Array
(
[0] => 000000
[1] => ff6600
)
)
假设您的输入数组看起来像
array('style1|000000','style2|ff6600', 'style3|22ff22')
你的循环中需要更多的逻辑。
// Initialize output array with an empty styles subarray and a links subarray
$out = array('styles'=>array(), 'links'=>array());
foreach ($styles as $key=>$value) {
// Loop over and split on the |
list($style, $link) = explode("|", $value);
// And append the two resultant values to their respective subarrays via []
$out['styles'][] = $style;
$out['links'][] = $link;
// list() is a useful construct for producing readable results with small arrays,
// but I could also have used an array to receive the
// results of explode()
// $split = explode("|", $value);
// $out['styles'][] = $split[0];
// $out['links'][] = $split[1];
}
print_r($out);
// Prints:
Array
(
[styles] => Array
(
[0] => style1
[1] => style2
[2] => style3
)
[links] => Array
(
[0] => 000000
[1] => ff6600
[2] => 22ff22
)
)
