Question

Array ( [0] => [null] [1] => [null] [2] => [null] [3] => [null] [4] => [null] [5] => [null] [6] => [null] [7] => [null] [8] => [null] [9] => [null] [10] => [{"SL":"2","S":"34","M":"4","L":"5","F":"5"}] [11] => [{"SL":"5","S":"3","M":"4","L":"5","F":"0"}] )

需要输出：

Array([0]=>[{"SL":"2","S":"34","M":"4","L":"5","F":"5"}] [1]=>[{"SL":"5","S":"3","M":"4","L":"5","F":"0"}])

Answer 1

您可以使用数组过滤器函数array_filter()来排除空值。

 array_filter($Array, function($val) { return $val !== null; })

Answer 2

$arr = array('abc',NULL,'rre',null,null,null,'dfg','fggh');

$emptyRemoved = remove_empty($arr);

function remove_empty($array) {
  return array_filter($array, '_remove_empty_internal');
}

function _remove_empty_internal($value) {
  return !empty($value) || $value === 0;
}

Answer 3

仅限过滤器＆＃34; null＆＃34;您可以在没有回调的情况下使用array_filter的值。要创建新键（0..n），请使用array_values（因为array_filter保留键）结果代码：

$result = array_values(array_filter($yourArray));

Answer 4

试试这个钩子：

array_filter($arr, function($var){return !is_null($var);} );

Answer 5

请试试这个：

_template

需要从数组中删除[null]
