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。$multiDimensionalArray = array( array('id' => 1, 'name' => 'value1'), array('id' => 2, 'name' => 'value2'), array(...
You might know how to find a value in an array or in a one dimensional array, but the same technique doesn’t work in a multidimensional array. So, you’re looking for the solution. Solution: Example: [php]<?php function multi_array_search($search_for, $search_in) { foreach ($sear...
首先使用 is_array() 函数来判断传入的变量是否为一个数组。然后使用 array_values() 函数将数组的值放入一个新的索引数组中。然后遍历新的索引数组,对每个值再次使用 is_array() 函数来判断其是否为一个数组,如果是,则说明传入的数组不是一维数组,返回 false。如果遍历完毕后都没有发现内部数组,说明传入的数组...
