Comparison operators (I can't seem to match variable values exactly)

wheeler08

I have the following IF statement:

If (!$upfile === "propertypics/"){
	$upfile = 'propertypics/'.$userfile_name;
}else{
	$upfile = "";
}

If $upfile IS equal to "propertypics/", I want it to NOT write the path and make $upfile blank. Otherwise, store the correct path in the variable $upfile.

When $upfile contains the value "propertypics/pic1.jpg", the IF statement is reading the "propertypics/" and assuming that it is a match.

i.e WHEN $upfile="propertypics/pic1.jpg"
The if statement checks to see if $upfile="propertypics/" and returns a true value. For some reason, it is matching only part of the value, not all of it.

Obviously it is not a match because there is more text there. How can I make it match EXACTLY what is in the variable $upfile?

(I have tried = and ==)

ok first off... if you are putting an exclamation mark to the right of a variable's $ sign, you are checking to see if it is false in itself...

so..

if(!$whatever)

Is saying "Is the variable that is named "whatever" empty?" if it is... then the if statement is true...

try using:

if($upfile != "propertypics/"){ 
echo "whatever";
} else {
echo "do whatever else";
}

I know what the syntax is doing.

Please look at the logic of what I am saying, not the code.

The facts:

WHEN $upfile = "propertypics/pic1.jpg" the comparison operators ===, ==, = are all interpreting the value "propertypics/" as "propertypics/pic1.jpg" .

My point is that it is for some reason looking at it as a LIKE and not matching the text exactly.

P.S. For some reason it doesn't work when I use '!= ' together, I have to use '!$upfile =')

You need to put the comparison in brackets.
Assuming $upfile has exactly "propertypics/" in it.
Otherwise you will need to use strstr() to do a substring comparison.

If ( !($upfile == "propertypics/") ){ 
    $upfile = 'propertypics/'.$userfile_name; 
}else{ 
    $upfile = ""; 
}

Actually, why not use the !== operator?

Strings have a numeric value of 0.
!$str should mean !0, and !0 is not 0 (duh)

Thanks Halfabee, it was the extra brackets that were needed!
