So I'm recreating link generation function from mysql to PDO and I have a problem.
$sth = $resDB->prepare("SELECT count(*) FROM downloads WHERE downloadkey = '{$strKey}' LIMIT 1");
$arrCheck = $sth->fetchAll();
if($arrCheck['count(*)']){
//key already in use
return createKey();
}else{
//key is OK
return $strKey;
}
Everything goes well until this line: if($arrCheck['count(*)'])
I get the error like this: Undefined index: count(*)
I just don't know how to change that line to PDO. Can you help me ?
Use an alias to refer to the column
SELECT count(*) as cnt FROM ...
$arrCheck["cnt"]
Try this using alias,
$sth = $resDB->prepare("SELECT count(*) as count FROM downloads WHERE downloadkey = '{$strKey}' LIMIT 1");
$arrCheck = $sth->fetchAll();
if($arrCheck['count']){
