真的很简单 PHP strlen/if 问题

Question

I am trying to take 2 strings, see what length they are, and if one is larger than the other, set it as $phonenumber , and the other as $extension . See below:

if(strlen($temp_ext) > 4)
{
    $extension = $temp_cid;
    $phonenumber = $temp_ext;
}
else
{
    $extension = $temp_ext;
    $phonenumber = $temp_cid;
}

This doesn't look like it works, though. I am still getting 10 digit numbers in extension, and 4 digit numbers in the $phonenumber variable. What am I missing?

Answer 1

Try this

if(strlen($temp_ext) > strlen($temp_cid))
{
    $extension = $temp_cid;
    $phonenumber = $temp_ext;
}
else
{
    $extension = $temp_ext;
    $phonenumber = $temp_cid;
}

Hope this helps.
