[Notation in the documentation?]

Hi there

 

 

Please can someone point me in the right direction, where in the documentation can I read up on the following notation?...

 

I am trying to figure out what the purpose of the braces around the variable are? $this->{$spec}

if (is_string($spec)) {

$subForm = $this->{$spec};

}

[PDO newbie question?]

IS there an easier way to get a single result from a PDO query than having to run a foreach when I already know that there should only be a single record or value being returned?

I tried using $myresult = $dbh->exec($sql); ...but only returns a 1

 

 

$dbh = new PDO("$Driver1:host=$Server1;dbname=$db1", $User1, $Password1);

try {

 

$sql = "SELECT FileVersion FROM FileVersion WHERE GroupID = $GroupID ORDER BY FileVersion Desc";

foreach ($dbh->query($sql) as $myrow)

{

$FileVersion = $myrow['FileVersion'];

}

 

$dbh = null;

}

catch(PDOException $e)

{

echo $e->getMessage();

}

[Concatenating Class Variables?]

Variable Variables???

 

I am used to concatenating variables like this when doing procedural PHP like this ....

 

$i=5;

${"varnumber_$i"} = 'This variable should be called varnumber_5';

 

How do I make a variable variable in a PHP5 class ?

How do I achieve the following without resorting to Case Statements?

 

.... here is my event handler in my class :

 

public function handleAction( $i ){

$this->handleEvent_$i

}

 

public function handleEvent_1 () {

echo "Handling Event1";

}

 

public function handleEvent_2 () {

echo "Handling Event1";

}

public function handleEvent_3 () {

echo "Handling Event1";

}
