[英]unique string from array of strings
I want to create a string that is unique from all the strings in an array. 我想创建一个与数组中所有字符串唯一的字符串。 I know that
unique_array
would create an array with unique values, but I want to create a new string that is unique from all the strings in the unique array. 我知道
unique_array
会创建一个具有唯一值的数组,但是我想创建一个新字符串,该字符串与唯一数组中的所有字符串都是唯一的。 I want this in PHP. 我想要在PHP中。
For example, if I have "1"
, "2"
strings in the unique array. 例如,如果我在唯一数组中有
"1"
, "2"
字符串。 I would like to create a "3"
string or "a"
string or any other string with a different name then "1"
, and "2"
. 我想创建一个
"3"
字符串或"a"
字符串或其他名称不同于"1"
和"2"
其他字符串。 Serialize a new string and add it into the array and check for unique_array
sounds like it should work, but is there a simpler way to do it? 序列化一个新字符串,并将其添加到数组中,并检查是否应该起作用,以检查
unique_array
声音,但是有没有更简单的方法呢?
How about 怎么样
sort($array);
$array[] = end($array) + 1;
