Thoughts on small functions of php array_PHP tutorial

Recent projects have such a requirement for arrays. The contents of the array itself may keep changing. If you know a certain key name of the array, how to get the next key name?

At first I thought it would be difficult to write, so I kept looking for array-related functions in books and searching online, but found none.

So I started writing it myself, and I didn’t expect it to be so easy.

[html]

/*

* Find the next key name of the current key name in the array

* $array array

* $keys Current key name

* Return the next key name

*/

function next_array($array,$keys){

$n=0;

foreach($array as $key =>$value){

if($n==1)

return $key;

if($key == $keys)

$n++;

}

}

I found that many times, you still have to rely on yourself.
