问题描述
新手问题 - 我试图删除与以'not__开始键的元素。
其内部laravel项目,所以我(可以)使用它的阵列功能。
我试图消除环路后的元素。这不删除任何东西,即它不工作:
函数fixinput($ arrinput)
{
$ keystoremove =阵列();
的foreach($ arrinput为$关键=> $值);
{
如果(STARTS_WITH($键,'not__'))
{
$ keystoremove = array_add($ keystoremove,'',$键);
}
}
$ arrinput = array_except($ arrinput,$ keystoremove);
返回$ arrinput;
}
请注意,这将不会对阵列的唯一任务。我想试试自己。 :)
谢谢!
解决方案
$ =过滤阵列();的foreach($数组$关键=> $值){
如果(strpos($键,'not__')!== 0){
$过滤[$关键] = $价值;
}
}
Newbie question - I'm trying to remove elements with keys that start with 'not__'. Its inside laravel project so I (can) use its array functions. I'm trying to remove elements after the loop. This doesn't remove anything, i.e. it doesn't work:
function fixinput($arrinput)
{
$keystoremove = array();
foreach ($arrinput as $key => $value);
{
if (starts_with($key, 'not__'))
{
$keystoremove = array_add($keystoremove, '', $key);
}
}
$arrinput = array_except($arrinput, $keystoremove);
return $arrinput;
}
Note that it won't be the only task on array. I'll try that myself. :)
Thanks!
解决方案
$filtered = array();
foreach ($array as $key => $value) {
if (strpos($key, 'not__') !== 0) {
$filtered[$key] = $value;
}
}
