[英]Sort multidimensional array PHP
從樣式數組:
Array
(
[0] => style1|000000
[1] => style2|ff6600
)
我做了這個循環
foreach($styles as $key=>$value){
$sort_values[] = explode('|',$value);
}
**和print_r($ sort_values)我得到:**
Array
(
[0] => Array
(
[0] => style1
[1] => 000000
)
[1] => Array
(
[0] => style2
[1] => ff6600
)
)
但我需要它是:
Array
(
[styles] => Array
(
[0] => style1
[1] => style2
)
[links] => Array
(
[0] => 000000
[1] => ff6600
)
)
任何幫助表示感謝,謝謝!
假設您的輸入數組看起來像
array('style1|000000','style2|ff6600', 'style3|22ff22')
您的循環中需要更多邏輯。
// 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
)
)
