In this tutorial, learn how to get the key of max value in an associative array in PHP. The short answer is: use the PHP max() to find the maximum value and array_search() to get the key of the max value. You can also use the PHP foreach loop or PHP for loop to find the ...
This code outputs all keys from the $user array. The result will be: Array ( [0] => name [1] => age [2] => email ). Searching for Specific ValuesFind all keys that have a specific value in an array. search_values.php
array_splice( array&$array, int$offset, ?int$length=null, mixed$replacement= [] ):array 把array数组中由offset和length指定的单元去掉,如果提供了replacement参数,则用其中的单元取代。 注意: array中的数字键名不被保留。 注意:如果replacement不是数组,会被类型转换成数组 (例如:(array) $replacement)。

array_multisort()可以用来一次对多个数组进行排序,或者根据某一维或多维对多维数组进行排序。 关联(string)键名保持不变,但数字键名会被重新索引。 注意: 如果两个成员完全相同,那么它们将保持原来的顺序。 在 PHP 8.0.0 之前,它们在排序数组中的相对顺序是未定义的。
array_pad(array $array, int $length, mixed $value): array array_pad() 返回array 的一个拷贝,并用 value 将其填补到 length 指定的长度。如果 length 为正,则填补到数组的右侧,如果为负则从左侧开始填补。如果 length 的绝对值小于或等于 array 数组的长度则没有任何填补。 参数...
