what's "int()" of ASP in PHP?

What's wrong with this? I tried to translate it from ASP to PHP.

    echo '<option ';
	if int(letter_id) = int($row['letter_id']){
	echo 'selected';
	}
	echo ' value="'.$row['letter_id'].'"> Spoke '.$row['letter_id'].'</option>'."\n";

PHP:

In ASP it would've been:

<option <%if int(letter_id) = int(RS("letter_id")) then response.write "selected" end if%> value="<%=RS("letter_id")%>">SPOKE <%=RS("letter_id")%></option>

Code (markup):

 

I convert to integers like this:

$Number = 12.345;
$newNumber = (int)$Number;
echo "before: ". $Number;
echo"<br>after: ". $newNumber;

this will display:

before: 12.345
after: 12

Let me know if that helps

 

That's not what intended. I have a database table where I'm retrieving the values into a dropdown. By then selecting from one of the dropdown selection it should write selected next to it.

 

This solved:

    echo '<option ';
	if (intval($letter_id) == intval($row['letter_id'])){
	echo 'selected';
	}

PHP:

 

first up, the php if statement has to wrapped in ( )'s
i.e if($number!='1'){ echo 'not a number 1'; }else{ echo 'this is a number 1'; }

$sel=1;
echo '<option ';
if($sel==1 && intval($sel)){
echo 'selected';
}
echo ' value="'.$sel.'" yadda yadda yadda';

have fun with that one

 

lol, you got it =)
