Php alphabet

[Linjon]

Hello. How to make two variables to alphabet?

 

Example:

$variable1 = ace

$variable2 = bd

and script makes abcde

 

Hope you understand, sorry for my bad English

$arr = str_split($variable1 . $variable2);
sort($arr);
echo implode($arr);

 

str_split

sort

implode

Thanks Alex. I have question again. If there is "a" in $variable1 and also there is "a" in $variable2 then it will echo "aa". How to make it show "a" once ?

Use array_unique to get rid of duplicates:

 

$arr = str_split($variable1 . $variable2);
sort($arr);
echo implode(array_unique($arr));
