Hi,

why is OutStr=0 after executing below code?
I just want to add all the Items in the Array into a String....the String
should look like this after:
[String]
<option>ElementA</option>
<option>ElementB</option>
<option>ElementC</option>
[/String]

CODE

$count=count($spamArray);
$outStr="";
for($j=0; $j<$count; $j++ )
{
$outStr+="<option>".$spamArray[$j]."</option>n";
}

why is $OutStr=0?
Thank you!

It's 0, because you are summing strings (which are evaluated 0, since they
are non-numeric) instead of concatenating. Use the concatenation operator .
instead.
Like this:
$outStr.="<option>".$spamArray[$j]."</option>n";

Thinking or reading the manual helps also.
