How to remove an element from an array in php

1. Directly use the "unset()" function to pass in an element in the array "unset()";

$arr = [
  'username' => 'xiaoliang',
  'email' => '123456@qq.com'
];

unset($arr['username']);

2. Use the "array_splice()" function to remove an element from the array;

if(($key = array_search('day',$arr))){
    array_splice($arr, $key,1);
}

3. Use "foreach" to loop to a specific element to "unset" ()" is enough.

foreach($array as $k=>$v){
  if($v == 'day'){
    unset($array[$k]):
  }
}
