Yeah, I know. This is the client's hair-brained idea. I told him I'd
take a look. The problem all goes back to how they are handling their
data.
They are using LDAP for data storage. Each record has a 'key' value
which they want to be unique. The key is generated from a combination
of three user-input values, so it's not as easy as 'Browns.' In the
current system, there is no check in place to ensure that the key is
unique. In the new system, they want the script to generate the key
and ensure its uniqueness.
I took your original code and modified it extensively. It now uses
recursion to get a unique value and I add that value to the array. I
put echo statements at the end for debuging purposes. I also
hardcoded the "$newteam". Have a look and see if this solves your problem:
<?php
$teams=array(
'Reds',
'Browns',
'Bengals',
'Cavaliers',
'Blue Jackets',
'Indians'
);
$unique=false;
//$newTeam=$_POST['newTeam'];
$newTeam = 'Browns';
function checkDuplicate($value,$teams,$cnt=1){
$chk = in_array($value,$teams);
if (!$chk) {
$teams[] = $value;
return array(true,$teams);
}
$nt = substr($value,0,-1) . $cnt++;
list ($chk,$teams) = checkDuplicate($nt,$teams,$cnt);
while (!$chk) {
$nt = substr($value,0,-1) . $cnt++;
list ($chk,$teams) = checkDuplicate($nt,$teams,$cnt);
}
return(array($chk,$teams));
}
list($unique,$teams) = checkDuplicate($newTeam,$teams);
echo '<pre>' . var_export($unique,true) . "\n";
echo print_r($teams,true) . '</pre>';
list($unique,$teams) = checkDuplicate($newTeam,$teams);
echo '<pre>' . var_export($unique,true) . "\n";
echo print_r($teams,true) . '</pre>';
?>
