Is it possible to implode array's indexes? 是否有可能破坏数组的索引? A function is returning me an array and what I need are the indexes of that array so I want to implode only inexes with comma or any other character for my db work 一个函数正在返回一个数组,我需要的是该数组的索引,所以我想只用逗号或任何其他字符来破坏我的数据库工作
You mean something like this... 你的意思是这样的......
implode(',', array_keys($some_arr));
... right? ... 对? ) Here's documentation for array_keys
; 这是array_keys
的文档 ; in short, when called with a single argument (an array), this function just returns all its keys (as array). 简而言之,当使用单个参数(数组)调用时,此函数只返回其所有键(作为数组)。
