知道其名称从数组中删除元素

Question

我在PHP中有这个数组

array(5) {
  ["mai_id"] => string(1) "3"
  ["mai_logo"] => string(0) ""
  ["mai_title"] => string(16) "Vitrine Cultural"
  ["mai_description"] => NULL
  ["mai_description2"] => NULL
}

我想删除["mai_description"]并仅获取

array(5) {
  ["mai_id"] => string(1) "3"
  ["mai_logo"] => string(0) ""
  ["mai_title"] => string(16) "Vitrine Cultural"
  ["mai_description2"] => NULL
}

有什么办法吗？

Answer 1

是的，请使用unset()

unset( $array['mai_description'] );

Answer 2

unset($array['mai_description'])

但请使用文档。

Answer 3

unset($array["mai_description"]);

应该这样做。
