使用foreach从数组中删除元素

Question

this is my array output

Array ( [0] => Site=[121] [1] => #asasasas [2] => Devices=34343 [3] => DeviceID=[hjhghg])

Now I want to remove the value with key if it value contains # symbol... I have tried this, but does not seem to work....

foreach ($myarray as $key=>$value) {
    if (strpos($value,'#') !== false) {
        unset(($myarray[$key]);
    }
}

any ways to fix this??

Updated this is my actual array array_values($lines) i have already tried this...

if(strpos($value,'#') !== false) {
                           unset(array_values($lines)[$key]);
                       }

Answer 1

unset后，您的括号中的括号过多

Answer 2

This works fine for me

$arr = array (  0 => 'Site=[121]',
        1 => '#asasasas',
        2 => 'Devices=34343', 
        3 => 'DeviceID=[hjhghg]'
      );
foreach($arr as $key => $val){
  if(strpos($val,'#') !== false) {
       unset($arr[$key]);
   }
}
print_r($arr);
