使用循环在PHP中添加关联数组

Question

$usepassArray = explode(",", $implodedstuff);

for ($i = 0; $i < sizeof($usepassArray) ; $i = $i + 2)
{
    $finalArray += array($usepassArray[$i] => $usepassArray[$i + 1]);
}

So my $usepassArray is an 8 string long array of usernames and passwords. So $usepassArray[0] is the username, and [1] is the password. Im trying to make a associate array to pair up these usernames and passwords. I cant figure out how to append this to the end of the array, for some reason += is returning an error and I have been searching the internet for hours and nothing is working. The closest I have gotten is an array whithin an array.

It's not clear what your desired final structure is. If it's an array of username/password pair arrays, then you can just change this line:

$finalArray += array($usepassArray[$i] => $usepassArray[$i + 1]);

to

$finalArray[] = array($usepassArray[$i] => $usepassArray[$i + 1]);

This will give you a structure that looks something like this:

[['user1' => 'pass1'],
 ['user2' => 'pass2'],
 ...
 ['usern' => 'passn']
]

If on the other hand you don't want that level of nesting, i.e. you want something that looks like this:

['user1' => 'pass1',
 'user2' => 'pass2',
 ...
 'usern' => 'passn'
]

Then change that line to this:

$finalArray[$usepassArray[$i]] = $usepassArray[$i + 1];
