PHP get index of last inserted item in array
You can use key($a) together with end($a)
$a=array();$a[]='aaa'; foo($a);$a[3]='bbb'; foo($a);$a['foo']='ccc'; foo($a);$a[]='ddd'; foo($a);function foo(array $a) { end($a); echo 'count: ', count($a), ' last key: ', key($a), "\n";}prints
count: 1 last key: 0count: 2 last key: 3count: 3 last key: foocount: 4 last key: 4
You can use the end() function to get the last element in an array, and array_keys() to return an array of the array-keys. Confusing. In practice, it works like this:
$key = end(array_keys($array));Credit goes to hollsk in the comments.
