Inspecting k=>v pairs for nils

[cranjled]

I have a variable that holds an array. What I need to do it check if all the variables equal a particular value. What's the easiest way to do this.

For example, in the namespace, I have this floating around,

$ThisVar = array('K1' => 'V1', 'K2' => 'V2', etc, etc);

Altogether, there are 10 k => v pairs in the array...and what I need to do is inspect each key to see if the value is set to ''...so for example, this block of code would produce the desired results:

if (($ThisVar['K1'] == '') &&
  ($ThisVar['K2'] == '') &&
  ($ThisVar['K3'] == '') &&
  ($ThisVar['K4'] == '') &&
  ($ThisVar['K5'] == '') &&
  ($ThisVar['K6'] == '') &&
  ($ThisVar['K7'] == '') &&
  ($ThisVar['K8'] == '') &&
  ($ThisVar['K9'] == '') &&
  ($ThisVar['K10'] == '')) {
...do this...
}
else {
...do that...
}

So...while the method checks the array as I need it to, it seems awfully verbose, don't you think? How would you do it?

Thanks,

John

foreach($ThisVar as $k => $v)
{
    if($v)
    {
        //do this
    }else
    {
        // do that
    }
}

Er...just reread your question. You probably want more like this:

$flag = 0;
foreach($ThisVar as $k => $v)
{
    if($v){$flag = 1;break;}
}

if($flag){ /*do this*/ }else{ /*do that*/ }

What I need it to do is check them all...but only do an "if" if all of the $v's equal ''. If even one $v != '' then I don't need the if to happen.

Well, you're in luck, cause that's what the second code should do. Try testing if(!$flag) or switch "do this" with "do that"...I'm not sure exactly what you need.
