我有以下数据结构:
$campaigns =
Array
(
[0] => Array
(
[subject] => cca-cpg
)
[1] => Array
(
[subject] => cleanup-cpg
)
[2] => Array
(
[subject] => gas-cpg
)
[3] => Array
(
[subject] => pollinators-cpg
)
)
我想结束的是:
$campaigns = ['cca-cpg','clean_up-cpg','gas-cpg','pollinators-cpg'];
this will work:
$newCampaigns=[];
for($i=0;$i<count($campaigns);$i++){
array_push($newCampaigns,$campaigns[$i]['subject'];
}
但我想知道是否有更好的方法来做到这一点。数据直接来自mysql数据库
