如果当前元素是一个数组,则递归调用searchArrayPointer()函数来搜索子数组中的值。如果找到了匹配的值,则返回当前键名与子数组中匹配值的指针的组合。 然后,我们创建了一个多维数组$multiDimensionalArray,并指定要搜索的值为'subsubvalue2'。接下来,我们调用searchArrayPointer()函数来查找该值在数组中的指针
Searching in Multidimensional Arrays For multidimensional arrays, combine array_search with array_column. multi_array_search.php <?php $users = [ ["id" => 1, "name" => "Alice"], ["id" => 2, "name" => "Bob"], ["id" => 3, "name" => "Charlie"] ]; $key = array_search(...
使用array_column 和in_array:如果你需要在一个多维数组中查找一个值,可以使用 array_column 函数从数组中提取一个特定列,然后使用 in_array 函数检查该列中的值是否存在。$multiDimensionalArray = array( array('id' => 1, 'name' => 'value1'), array('id' => 2, 'name' => 'value2'), array(...
== false) { return $result; } } else { if ($value == $searchValue) { return $key; } } } return false; } $multidimensionalArray = [ 'key1' => 'value1', 'key2' => [ 'key3' => 'value2', 'key4' => [ 'key5' => 'value3' ] ] ]; $searchValue = 'value3'; $re...
if ($key !== array_search($value, $array)) { $isOneDimensional = false; break; } } if ($isOneDimensional) { echo “是一维数组”; } else { echo “不是一维数组”; } “` 以上是三种常用的方法来检查一个变量是否是一维数组。可以根据具体的需求选择合适的方法来判断。
You might know how to find a value in an array or in a one dimensional array, but the same technique doesn’t work in a multidimensional array. So, you’re looking for the solution. Solution: Example: [php]<?php function multi_array_search($search_for, $search_in) { ...

based on worldclimb's arem(), here is a recursive array value removal tool that can work with multidimensional arrays.function remove_from_array($array,$value){ $clear = true; $holding=array(); foreach($array as $k => $v){ if (is_array($v)) { $holding [$k] = remove_from_arr...
