Split string by last character and save to array?

I have several strings that look like:

longname1, anotherlongname2, has1numbers2init3

I would like to use str_split to split off the last character of the strings. Eg:

Array ( [0] => longname [1] => 1 )
Array ( [0] => anotherlongname [1] => 2 )
Array ( [0] => has1numbers2init [1] => 3 )

I can get the number alone using substr($string, -1); but need to find an efficient way of retrieving the remainder of the string.

I have tried:

str_split($string,-1);

but of course this doesn't work.

Would anyone know what I could do?

Solution

  • You can subtract one from the strlen() of your $string inside of str_split():

    <?php

$string = 'longname1';
print_r(str_split($string, strlen($string) - 1));

    Output:

    Array
(
    [0] => longname
    [1] => 1
)

    This can be seen working here.
