在php中将字符串组合成一个数组

Question

I have a web service to identify people and their functions from an external database that returns me a set of data if the login is successful. The data (that interests me right now) is separated in different strings as follow:

$groups="group1, group2, group3"
$functions="member, member, admin"

The first element of the string $groups corresponds to the first element of the $functions string.

We can have empty spots in the strings:

$groups="group1,, group3";
$functions="member,, admin";

What is the best way to combine them to obtain:

$usertype(
    group1=>member, 
    group2=>member, 
    group3=>admin,
);

Then I plan to use array_search() to get the name of the group that corresponds to a function.

Answer 1

Have you tried a explode($delimiter , $string) and then filter the array? I think that would be a good way of doing it:

$groups="group1,, group3";
$functions="member,, admin";

$groups_array = array_map('trim',explode(',', $groups));
$functions_array = array_map('trim',explode(',', $functions));

$final = array();
for ($i = 0; $i <= count($groups_array); $i++) {
    $final[$groups_array[$i]] = $functions_array[$i];
}

$merged = array_combine($groups_array, $functions_array);
